Abstract: installed correctly is the key to the successful operation of the mass flowmeter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. According to the theory of coriolis mass flowmeter is developed a new direct measurement of closed pipe flow of fluid mass flow meter. It has high measuring accuracy, good long-term stability and measuring accuracy is not affected by medium density change. Basically can suddenly. More flow meter manufacturers choose model price quote you are welcome to inquire, here is installed correctly is the key to the successful operation of the mass flowmeter scale article details. According to the theory of coriolis mass flowmeter is developed a new direct measurement of closed pipe flow of fluid mass flow meter. It has high measuring accuracy, good long-term stability and measuring accuracy is not affected by medium density change. Basically can ignore medium the influence of temperature and pressure changes on the measuring accuracy. Thus. In many fields of requires high accuracy of measurement is widely used. Mass flowmeter is also can be used as a high precision on-line densimeter, used to measure fluid density and temperature in real time. At the same time can also calculate the volume flow accordingly, media content, concentration and other parameters. Mass flowmeter main application fields: food industry: dairy products, wine, beverage, syrup, chocolate, edible oil and other mass flow measurement of oil chemical industry: olefins and light olefins ( Including gasoline and diesel) , aromatic hydrocarbon and liquefied petroleum gas mass flow measurement of various petrochemical products of fine chemical industry, salt chemical industry, resin chemical, chemical additives, etc of raw materials and the quality of the product flow metering pharmaceutical industry: medicine products of the production of raw materials and finished products quality flow metering storage and transportation industry: all kinds of chemical raw materials, such as oil storage, loading and shipment online mass flow measurement of mass flowmeter is mainly applied to the more important measurement occasions: all kinds of fluid materials of feed mixing and batch production of measurement fluid flow measurement and control in the process of rapid and changeable fluid density of online measuring product quality control and monitoring, monitoring of mass flowmeter although has many advantages, but experience has shown its installed correctly or not, to the success of mass flowmeter operation effect was considerable. In shandong province in a new project of 600000 tons of caustic soda, users choose the three brands of mass flowmeter for measuring instrument. Among them: four American Emerson brands (used for liquid chlorine metering, three Germany E + H DN80 used in the measurement, 50% caustic soda 4 DN100 for 32% of the brand in the domestic caustic soda measurement. But as a result of the user and supplier communication problems, it has not been 12 sets of mass flowmeter installation as required. As a result, all the 12 sets of mass flowmeter after the operation, with small loadometer weighing error zui was 1%, the liquid chlorine metering zui big eight. 5%. Not only by using the real case shows that domestic brands mass flowmeter is also the world famous brand products, its installed correctly or not have great influence on its successful operation. 一、安装前应了解以下几方面问题:1汽泡问题。 When used for liquid flow measurement, when the entrainment of the volume of a gas content more than 1% ~ 5% content, mass flowmeter will stop working. These bubbles attenuation to the vibration of the flow tube coriolis force, gas should be eliminated before the sensor. If difficult to achieve, as far as possible to reduce gas content, As far as possible, improve the pressure inside the sensor) To ensure that the bubble was evenly dispersed into smaller bubbles ( Maintaining high liquid velocity) 。 Increase in front of the case of liquid chlorine metering error is related to this. When the pressure below the vapor pressure of liquid, will produce bubbles. By the geometry of a flow tube and liquid flow sensor at the ends of the pressure drop caused by the effective pressure of the liquid to the steam pressure, gas to liquid in the pipe of sensor and entrainment bubbles of the same effect. Sensor size once established, can calculate the back pressure necessary to sustain the liquid state. Sensor to be installed to meet the required back pressure. 2 沉淀物与悬浮物。 Mass flowmeter can calculate two kinds of solution or the composition of the quality of the paste is a kind of component content. The density of accurate measurement is must be avoided: sediment attached on the measuring tube wall or solid particles precipitated from the suspension ( The low velocity) 。 3 安装方向。 Mass flowmeter in theory can be two-way measurement. But because the outflow coefficient of two flow is different, so should be installed according to the manufacturer to manufacturer at a given flow. Mass flow meter can be installed in horizontal or vertical line. Installation direction depends on the applications. Some of the geometry of the mass flowmeter ( Except for straight tube) Under the direction of some kind of installation would gather some solid or gas phase. If must be installed vertically and fluid flow from top to bottom, it is necessary to take measures to ensure that no gas inlet pipeline from sensor into the sensor. In addition to the special circumstances, is not recommended side ( A flow tube above the other) 。
The global market was valued at rosemount coriolis mass flow meter in low flow turbine flow meter and is expected to reach a market value of vortex flow meter manufacturer by u shape coriolis mass flow meter, with a CAGR of endress hauser coriolis mass flow meter during the forecast period.
Beijing Sincerity Automatic Equipment Co., Ltd intends to make enough profit to generate a fair return for our investors and to finance continued growth and development in mass flow meter.
With so many suggestions and tips on diferent solutions to digital fork density meter issues, it is truly important to know how to find the most appropriate mass flow meter at economical price.
