Urea production plant in henan zhongyuan chemical group, adopted two electromagnetic flowmeter. One is used for measuring high pressure of the inlet flow pump; The other is hydrolysis liquid flow measurement. No matter in practical application on the response speed, and other various features are able to meet the needs of the process. But there have been some issues we unexpected. Since October 89 completed and put into operation, only high pressure of the inlet pump flow measurement of electromagnetic flowmeter it broke two, another one of hydrolytic waste liquid damage of electromagnetic flowmeter has happened many times. The emergence of these problems in terms of process operation or from the consumption on production cost is increased quite a burden to our factory, in this paper, combining with our application, makes a discussion on this question. Working principle and characteristics of electromagnetic flowmeter 1, the working principle of the electromagnetic flowmeter system made up of transmitter and transducer, between the two by two with double shield cable connections, transducer installed on the pipeline system, while the converter can be installed in the middle of the scene or room. Instrument of measuring principle is based on Faraday's law of electromagnetic induction: when a conductor in magnetic field for cutting lines of magnetic force movement, at opposite ends of a conductor will produce inductive electromotive force. This law is applied to the conductive fluid is also established. If the magnetic field strength for B, pipe diameter D, induction electric potential for E, you can prove that the volume of the pipe flow of Qv = D / 4 & times; （ E/B） The type B and D are set in the table, 'E' is for measuring pipe via the transmitter on a pair of electrodes to measure the actual electromagnetic flowmeter is based on the principle of work. Visible electromagnetic flowmeter is volume flow measurement instrument, it has to do with the fluid temperature, pressure, density, viscosity and conductivity and other physical properties. 2, the characteristics of the electromagnetic flowmeter, electromagnetic flowmeter has the following characteristics: ( 1) Sensors to measure the medium contact and can be used for corrosive conductive medium flow measurement; （ 2) Span a wide range, the same range of electromagnetic flowmeter ratio of 1:100; （ 3) No pressure loss; （ 4) No moving parts (testing part 5) Positive and reverse the flow of fluid can be determined; （ 6) Fast response speed. These are the advantages of electromagnetic flowmeter, but it also has some limitations and shortcomings. （ 1) Must be conductive: (measured medium 2) Due to limited by sounding pipe lining materials, general use temperature range of 0 ~ 200 ℃, and because of the electrode is mounted on the tube, the working pressure for electromagnetic flowmeter. （ 3) Electromagnetic flowmeter is complicated, the price is higher. 3, the application of electromagnetic flowmeter FT - our factory of the inlet pump flowmeter 09101 for the German FISCHER& POTER products company, since its launch in October 89, has replaced the two pieces, zui using DX1221 type at the beginning of the electromagnetic flowmeter shell with stainless steel, measure the tube wall with ptfe, converter closed within a rectangle metal shell, the internal circuit boards have a four-digit data set, can make measurements of indicator.

Abstract: The selection and installation information of flow meters are provided by excellent flow meter and flow meter manufacturers. Flow measurement of gas-liquid two-phase flow The phenomenon that liquid and its vapor or gas and liquid with different components flow together is called gas-liquid two-phase flow. The former is called single-component gas-liquid two-phase flow, and the latter is called multi-component gas-liquid two-phase inflow gas-liquid two-phase flow in power, chemical industry, and stone. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the selection and installation of flowmeters. Flow measurement of gas-liquid two-phase flow The phenomenon that liquid and its vapor or gas and liquid with different components flow together is called gas-liquid two-phase flow. The former is called single-component gas-liquid two-phase flow, and the latter is called multi-component gas-liquid two-phase flow. Gas-liquid two-phase flow is common in industrial equipment such as power, chemical industry, petroleum and metallurgy. There is a flow velocity difference between the liquid phases, and this relative velocity should be taken into account when measuring flow. Manufacturers usually claim that liquids containing a few percent by volume of free gas have little effect on the flow indication, but there is no specific data on its influence. However, the information provided by the relevant literature indicates that the free gas in the liquid has an effect on the flow indication. , Different designs of instruments are very different, and the pressure, flow rate, viscosity of the fluid and the distribution state of the gas in the liquid are different, and the effects are also different. Therefore, it is best to install an air eliminator upstream of the flow meter. When the liquid contains a small amount of gas, the distribution of the gas in the liquid is in the form of tiny bubbles, which can be measured by an electromagnetic flowmeter, but the measured volume flow of the bubble mixture. When the amount of gas contained in the liquid increases, the geometric size of the bubble gradually increases, and then transitions to a slug-like structure. When the size of the bubble is equal to or larger than the size of the end face of the electrode of the flowmeter and passes over the electrode, the electrode may be covered by the gas, causing the circuit to be disconnected instantaneously and the output shaking phenomenon. Flow measurement of liquids with high saturated vapor pressure The following takes liquid ammonia as an example to discuss the flow measurement of liquids that are easy to evaporate, such as ethylene, propylene, and vinyl chloride. There are two major differences between liquid ammonia flow measurement and water flow measurement and oil flow measurement: ① The saturated vapor pressure of liquid ammonia is high, and its boiling point is -33.41 under standard atmospheric pressure conditions, so it must be transported and stored under pressure conditions. ; ② In the flow measurement of this kind of fluid, it is easy to generate cavitation and accompanying cavitation at the outlet of the flowmeter due to the pressure loss of the instrument, causing the flowmeter to indicate a high value and the flow primary device to be damaged. The same situation is encountered in the flow measurement of liquid ethylene, propylene, etc. The problems encountered in the liquid ammonia flow measurement and their treatment methods analyzed here also have reference value for the flow measurement of other liquids with high saturated vapor pressure. 1. Characteristics of liquid ammonia flow measurement 1) The gas-liquid interface of liquid ammonia stored in the storage tank is generally in a gas-liquid equilibrium state. Figure 4-46 shows a typical flow measurement of liquid ammonia flow in an ammonia plant: the synthesis gas, gaseous ammonia and liquid ammonia mixture from the ammonia condenser are separated in the ammonia separator, and the liquid ammonia is adjusted by the flow meter and the liquid level. The valve is sent to the low pressure ammonia intermediate tank. Obviously, at the gas-liquid interface between the ammonia separator and the intermediate tank in the figure, the gas-liquid two phases are in equilibrium. Two-phase flow should be avoided as much as possible in the flow measurement of liquid ammonia. However, liquid ammonia that is close to the gas-liquid equilibrium state, when flowing through the flow meter, if the pressure loss is large, it is easy to cause partial gasification, which affects the measurement accuracy. 2) The temperature coefficient of fluid density is large. From the p=/(i) function table of liquid ammonia, it can be seen that under normal temperature conditions, the density of liquid ammonia changes by more than 0.2% for every 1 °C change in the temperature of liquid ammonia. Therefore, the measurement of liquid ammonia must be temperature compensated 3) High accuracy is required. According to the relevant documents of the former Ministry of Chemical Industry, the measurement of liquid ammonia should reach level 1 accuracy. If effective measures are not taken, it is difficult to achieve this requirement 04) Fluid is flammable and explosive. Explosion-proof instruments should be selected when selecting instruments, and explosion-proof regulations should be followed during instrument installation, use and maintenance. 5) The measured medium is corrosive. Ammonia has a strong corrosive effect on copper and other materials, so’The part of the instrument that is in direct contact with the measured substance should be able to withstand the corrosion of ammonia, and the electronic circuit part of the instrument should have a protection capability of 1P67 or above to prevent the corrosion of the electronic part by corrosive gases in the surrounding environment. 2. Cavitation and cavitation and preventing fluid vaporization problems, in the pipeline where liquid flows, if the pressure in a certain area drops below the saturated vapor pressure of the liquid’Then the liquid in this area will generate air bubbles, and these air bubbles will accumulate near the low pressure area, and air pockets will be formed. Lai Wei is in charge of the ship—A gas appeared in the area where the bowl remained unchanged. In the water flow pipeline, the bubbles mainly contain water vapor, but because a certain amount of gas is dissolved in the water, a small amount of gas precipitated from the water is also entrained in the bubbles. When the bubbles follow the water flow to an area of ​​high pressure’The vapor in the bubble will re-condensate into a liquid. At this time, the bubble will deform and rupture. The surrounding liquid flows to the center of the bubble, and a violent impact occurs. The g force increases sharply, and its value can reach hundreds of atmospheres. The material on the wall of the runner is continuously impacted, which causes the material to be eroded. If a flow meter is installed in the pipeline, the cavitation phenomenon will cause the measurement error to increase’and can damage—secondary device.

Mass flowmeter is an instrument with accurate medium flow detection and low installation requirements in existing industrial production. Because it can directly detect the quality, density and temperature of the medium flowing through the internal measuring tube of the instrument, there is no strict laminar flow for the flow state of the medium. Requirements, like a regulating valve, it can be installed arbitrarily, which greatly facilitates the construction and installation on site. The main scope of use of the mass flowmeter: It is mainly used to measure the mass flow, total amount and density of the medium. The concentration of the two liquids, the ratio of raw materials in the process, etc. As for it is mainly applicable to the petroleum industry, such as crude oil production measurement, water content, single well production measurement, crude oil transportation measurement, chemical industry, food industry, pharmaceutical manufacturing industry, such as liquid drug production measurement, paper industry, such as pulp measurement, textile Printing and dyeing industry, energy transmission measurement, such as liquefied gas measurement, environmental protection industry, such as sewage treatment; desulfurization process to measure the density of slurry. This kind of flowmeter can play a very effective role in batching and batch measurement of various incoming materials, measurement and control of material flow in the process, rapid and variable density measurement, and product quality monitoring. , The measurement principle of the mass flowmeter: ①The mass flowmeter adopts thermal measurement, and the flow rate is measured by the molecular mass taken away by the split molecules. changes that affect the measurement results. At the same time, it is also a relatively accurate, fast, reliable, efficient, stable and flexible flow measuring instrument, which will be more widely used in petroleum processing, chemical industry and other fields, and it is believed that it will show great potential in promoting flow measurement. ②The mass flowmeter can also measure the density of the medium and indirectly measure the temperature of the medium. Since the transmitter is an intelligent instrument with a single-chip microcomputer as the core, it can derive more than a dozen parameters for users to use based on the above three basic quantities. Because of its flexible configuration, powerful functions, and high performance-price ratio, this flowmeter is a new generation of flowmeter. ③ With the improvement of automation level, many production processes have put forward new requirements for flow measurement. The chemical reaction process is controlled by the quality of the raw materials. The heating and cooling effects of steam and air flow are also proportional to the mass flow rate.

Introduction

Are you interested in measuring the flow rate of liquid or gas in a system? Building a flow meter can be a cost-effective and rewarding project, allowing you to create a device that meets your specific requirements. Whether you are a hobbyist or a professional looking to build a flow meter for industrial use, this article will guide you through the process. In this article, we will cover the key components, steps, and considerations for building a flow meter from scratch.

Choosing the Right Flow Measurement Technology

Before diving into the construction of a flow meter, it's crucial to choose the right flow measurement technology for your specific application. There are various flow measurement technologies available, each with its own advantages and limitations. Some of the most common technologies include differential pressure, positive displacement, turbine, electromagnetic, ultrasonic, and thermal flow meters.

Differential pressure flow meters, for example, operate based on the pressure drop across a constriction in the flow path. Positive displacement flow meters, on the other hand, measure the volume of fluid passing through the flow meter by counting the number of times a piston or a rotor repeatedly fills and empties the measuring chamber. Electromagnetic flow meters, as the name suggests, utilize the principles of electromagnetic induction to measure the flow of conductive liquids. When choosing the right flow measurement technology, consider factors such as the type of fluid, flow rate range, accuracy requirements, and environmental conditions.

In this section, we will delve into the various flow measurement technologies, their principles of operation, advantages, and limitations. By understanding the different technologies, you can make an informed decision on the most suitable approach for your flow meter project.

Key Components for Building a Flow Meter

Building a flow meter involves incorporating various components that are essential for accurate and reliable flow measurement. These components include the primary element, transmitter, sensor, signal processing unit, and display. The primary element, which is in direct contact with the fluid flow, creates a measurable signal based on the velocity or mass flow rate.

The transmitter processes the raw signal from the primary element and converts it into a standardized output signal, such as a 4-20mA current loop or a digital communication protocol. The sensor, whether it's a pressure sensor, temperature sensor, or flow sensor, plays a crucial role in detecting, measuring, and transmitting the relevant parameters to the transmitter. The signal processing unit, often integrated into the transmitter, performs calculations and compensations to ensure accurate flow measurement. Finally, the display provides the user with real-time flow rate readings and relevant information about the fluid being measured.

In this section, we will discuss each of these key components in detail, explaining their functions, types, and considerations for selection. By understanding the core components of a flow meter, you can effectively plan and assemble the necessary parts for your DIY flow meter project.

Building the Physical Structure of the Flow Meter

Once you have selected the appropriate flow measurement technology and acquired the necessary components, it's time to build the physical structure of the flow meter. The construction of the flow meter involves designing and assembling the primary element, housing for the components, electrical connections, and mounting provisions.

The primary element, whether it's an orifice plate, a turbine rotor, an electromagnetic coil, or an ultrasonic transducer, needs to be securely installed in the flow path to ensure accurate measurements. The housing for the components should provide protection against environmental factors, such as moisture, dust, and temperature variations. Additionally, the electrical connections must be properly routed and insulated to prevent any interference with the flow measurement signals.

In this section, we will provide step-by-step instructions for building the physical structure of a flow meter, including the assembly of the primary element, enclosure for the components, wiring of electrical connections, and installation of the mounting provisions. By following these guidelines, you can create a robust and reliable flow meter that meets your specific requirements.

Calibration and Testing of the Flow Meter

After constructing the physical structure of the flow meter, the next crucial step is calibration and testing. Calibration involves adjusting the flow meter to ensure its measurements are accurate and consistent with the actual flow rates. Testing, on the other hand, involves verifying the performance of the flow meter under various flow conditions, such as different flow rates, fluid viscosities, and temperature ranges.

During the calibration process, you will need to compare the output of the flow meter with a reference standard, such as a certified flow measurement device or a known flow rate. This allows you to make adjustments to the flow meter's settings, such as scaling factors, zero offsets, and linearization, to achieve accurate flow measurements. Testing the flow meter involves subjecting it to different operating conditions to assess its response, linearity, repeatability, and stability.

In this section, we will provide detailed guidelines for calibrating and testing a flow meter, including the equipment required, calibration procedures, testing methodologies, and data analysis techniques. By following these guidelines, you can ensure that your DIY flow meter delivers reliable and accurate measurements in real-world applications.

Summary

Building a flow meter from scratch can be a challenging yet rewarding endeavor, allowing you to tailor a flow measurement device to your specific needs and applications. By choosing the right flow measurement technology, incorporating key components, constructing the physical structure, and calibrating/testing the flow meter, you can create a custom-built device that meets the accuracy, reliability, and performance requirements of your flow measurement system. Whether it's for personal experimentation, academic learning, or professional use, building a flow meter provides valuable insights into the principles of flow measurement and instrumentation.
