In vortex flowmeter for steam measurement need to pay attention to what?

Steam divided into saturated steam and superheated steam, in general, manufacturers will give saturated vortex flowmeter, superheated steam mass flow rate range table for user selection, in order to determine the diameter size.

For superheated steam to compensate the temperature and pressure, electromagnetic flowmeter for real saturated steam temperature or pressure compensation, according to temperature and pressure when measuring density check table to ensure the required quality traffic.

Due to the condition changes, when actual measurements of saturated steam and superheated steam may deviate from the original state of design, makes the usually by steam temperature and pressure to calculate its density change, the relationship between affect measurement accuracy.
1.

In superheated steam flow computing devices according to the density of superheated steam temperature and pressure look-up table to calculate the mass flow rate, but when the superheated steam after long distance transmission, or due to improper measures of pipeline insulation, often because of the temperature to reduce the heat loss from overheating state into the critical saturation state, and even some steam condense into droplets by a phase change, then become wet saturated steam (
Too full steam)
。

The output of the vortex flowmeter with only through the measuring tube is directly proportional to the fluid velocity, when moisture saturated steam, water droplets on the influence of vortex street flowmeter output negligible, so you can think of vortex street flowmeter output entirely by various steam dry wet full part (
Saturated part)

Caused, and the density of dry part according to pressure or temperature compensation pinpointed.

Steam metering part if the two sides agreed by steam when clearing fees, condensed water not to collect fees, the phase transition to measure the impact of small, can be ignored.

If also in accordance with the steam condensed water fee, the vortex street flowmeter measurement results on the low side.
2.

Wet saturated steam after the vortex flow meter installed in the pressure reducing valve, wet saturated steam suddenly significantly reduced pressure, fluid of adiabatic expansion, the droplets evaporate part, absorb heat of vaporization from the liquid and vapor phases at the same time, the lower the temperature of liquid, if the temperature is lower much or evaporates before humidity is higher, can make the temperature down to rapid and new pressure of the saturated temperature, establish a new equilibrium, steam is still the saturated steam at this moment, if the pressure to reduce a lot or evaporates before humidity is low, due to water evaporation and the lower the temperature is still higher than new pressure after the corresponding saturation temperature, the steam into superheated steam.

In fact this is not the electromagnetic flow.

More flow meter manufacturers choose model price quote you are welcome to inquire, here is stop work under electromagnetic flowmeter scale how hairdressing maintains article details.

We have to respond to the electromagnetic flowmeter is scientific and reasonable maintenance and maintenance method, downtime is when not in use, a lot of people found in the purchase of electromagnetic flow meter to use after a period of time, again using found inaccurate measurement data.

In fact this is not the quality problem of the electromagnetic flowmeter itself exists.

Because the user does not operate according to the instruction methods in maintenance and maintenance.

First, zero check and adjustment of the electromagnetic flowmeter maintenance electromagnetic flowmeter in operation before, after electrify must in the electromagnetic flow sensor with fluid under stationary state adjust the zero point.

After put into operation or to use condition periodically stop flow for zero check;

Especially on precipitation, easy pollution electrode, the cleaning liquid containing solid phase, at the beginning of the run should be checked, in order to obtain experience to determine the normal inspection cycle.

Ac excitation mode of electromagnetic flowmeter with rectangular wave excitation, are more likely to produce zero drift, so more attention should be paid to check and adjust.

Two sedimentary malfunction application example of the error.

One is drilling cementing engineering, the total flow perfusion slurry is an important process parameters, often with high-pressure electromagnetic flowmeter.

Instrument intermittent use, with finish to wash after sensor tube, the rest of the time are hollow tubes.

Due to inadequate cleaning, measuring residue slurry solidifying into a thin layer of tube wall, nearly two months accumulation form the insulating layer, covering the entire electrode surface, leading to run is not normal to zui eventually won't work.

Another is electrolytic cutting process on the test rig, saturated salt water flow is controlled by electromagnetic flowmeter, clearance after using a period found that traffic signal gradually weakened, 2 months after the signal is zero.

Reason is electrolytic iron deposition in the process of cutting tube wall, formation caused by short circuit.
Clear stratification is back to normal immediately.

Second, the regular inspection of electromagnetic flowmeter maintenance sensor performance first, roughly measure resistance between electrodes.

Disconnect between the converter and signal connection of sensor and sensor inside fluid-filled, to the two electrodes and grounding resistance value is measured with a multimeter, e. range is in the factory, and measured by two values the same.

Record the measured resistance value for the first time, after this value to judge the sensor failure reason (
If sediment is conducting or insulating)
Is useful.

Secondly, sensor emptying liquid, wipe the lining, after being completely dry megohm meter was used to measure the resistance between the two electrodes and earthing terminal.

Zui, check the excitation winding insulation resistance, sensor excitation coil, terminal and converter indirectly line by megohmmeter measuring insulation resistance of the coil.

Abstract: the electromagnetic flow meter scale measurement precision impact analysis information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.

Weinan and shunda manufacturer produces electromagnetic flowmeter is based on Faraday's law of electromagnetic induction and the design of a kind of flow measurement instrumentation.

More flow meter manufacturers choose model price quote you are welcome to inquire, here is a scale electromagnetic flowmeter measurement precision influence analysis for details.

Factory production of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction and the design of a kind of flow measurement instrument.

According to the principle of measurement of the electromagnetic flowmeter, the flow measurement is not affected by changes in the fluid density, such as temperature, pressure, and high measurement precision, pipe unimpeded flow components, minimal pressure loss.

These characteristics make electromagnetic flowmeter in statutory metrology and has been widely used in various types of production enterprises.

Technology small make up today for everyone to analyze the factors influencing the electromagnetic flowmeter measurement precision have?

Factors that affect the battery meter measurement analysis: 1.

The influence of the conductivity of the use of electromagnetic flowmeter premise is liquid to be tested must be electrically conductive and conductivity cannot be lower than the lower limit value.

Conductivity is lower than the lower limit value can produce measurement error cause can't use, universal threshold of electromagnetic flowmeter in (

S/cm between, depending on the model.

Electrical conductivity of the fluid to the converter should be the size of the input impedance.

Fluid conductivity is reduced, the output of the electrode impedance will increase, and caused by the converter input impedance load effect and produce error.
2.

The influence of the temperature of the liquid according to the principle of electromagnetic flowmeter, electromagnetic flowmeter is generally thought that measurement is not affected by temperature, but we found that in the process of the actual verification of electromagnetic flowmeter measurement is affected by a certain temperature.

Some hot water flow standard device, usually by electromagnetic flow meter as a standard table, the requirements of the temperature range for normal temperature to 85 ℃.

Found in the experiment verification, when the temperature is above 80 ℃, because the effects, such as lining of slight deformation measurement data with more than 1% of the change, the influence on high precision electromagnetic flowmeter is not to be ignored.
3.

Installation way the influence of electromagnetic flowmeter for fluid in a state of full package, and the velocity of uniform distribution.

If the flow velocity on central axis symmetry, induction electric potential is proportional to the average flow velocity.

If uneven flow velocity, flow each particle's position relative to the electrode geometry is different, have different size of the induced electromotive force on the electrode, the closer the electrodes, the bigger the induction electromotive force is generated by the speed of particles, easy to cause error.

Order to ensure the uniform velocity, need at least before the battery meter straight pipe is greater than or equal to 10 pipe diameters of straight pipe after 5 times greater than or equal to the length of the pipe diameter.

Electromagnetic flowmeter must be reliable grounding method at the same time, or vulnerable to fluctuations in value, etc.
4.

Running environment influence the induced voltage generated in the electromagnetic flowmeter is low, vulnerable to the outside world the influence of electromagnetic interference, so the installation should be as much as possible to avoid vibration source, magnetic source, and reliable grounding connection.

In general, requires grounding resistance less than 10 ohms.

And the installation of lightning protection requirements for explosion-proof products, grounding resistance should be less than 10 ohms.

At the same time should pay attention to the flowmeter can not be grounded in large electrical equipment, such as transformer, generator, grounding on the exterior of the variable frequency power supply.

Abstract: Information on the correct use and installation of orifice flowmeters is provided by excellent flowmeter and flowmeter manufacturers. Correct use and installation method of orifice flowmeter The integrated orifice flowmeter consists of three parts: sensing, transmission, and operation display. It is mainly suitable for saturated steam, superheated steam, compressed air, mixed non-flammable and explosive gases and hot water. of industrial metrology, to the above. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the correct use and installation method of orifice flowmeters. Correct use and installation method of orifice flowmeter The integrated orifice flowmeter consists of three parts: sensing, transmission, and operation display. It is mainly suitable for saturated steam, superheated steam, compressed air, mixed non-flammable and explosive gases and hot water. It can be used for the flow measurement, display, measurement and online automatic control of the production process of the above-mentioned fluids. The most important thing to pay attention to when putting into operation is that the pressure guiding pipe must be filled with water or injected with high temperature steam to cool before starting operation. The straight pipe section before and after the throttling part of the integrated orifice plate flowmeter must be straight. The straight pipe section used to install the throttling part should be smooth. If it is not smooth, the flow coefficient should be multiplied by the roughness to correct the sparseness. A sufficiently long straight pipe section is required before and after the throttling piece, and the upstream side of the throttling piece is an open space or diameter≥In the case of a 2D large container, the length of the straight pipe between the open space or the large container and the throttle shall not be less than 30D (15D). If there are other local resistance parts between the throttling part and the open space or the large container, in addition to the specified minimum straight pipe length 1 between the throttling part and the local resistance part, from the open space to the throttling part The total length of the straight pipe section between the flow parts shall not be less than 30D (15D). How to use the integrated orifice flowmeter correctly: 1. The pressure guiding pipe system is filled with cold water as the pressure guiding medium, and the measurement of high temperature steam is generally conducted through cold water. When the pipeline is not transporting steam, open the primary valve, pressure valve and balance valve, close the drain valve, and directly inject cold water from the water injection hole of the condensate tank until it is fully filled. Of course, the balance valve and pressure valve can also be closed, and the valve can be opened once to introduce high-temperature steam and slowly cool it into water. This method is generally not used because the steam temperature is too high and it is easy to damage the instrument. Special attention should be paid to the measurement of high temperature steam when the pressure guiding pipe is not filled with water or the temperature is very high and it is strictly prohibited to put it into operation. Measured compressed air and cold water directly use the medium pressure. 2. After the differential pressure transmitter is exhausted or drained, after the pressure guiding pipe is filled with water, sometimes a small amount of gas will accumulate in the pressure chamber of the differential pressure transmitter to affect the pressure guiding, which must be eliminated. Unscrew the bolts at the lower part of the positive and negative pressure chambers to drain the fluid. Generally, instruments newly put into operation do not need to be drained. Check that there is no leakage in the pressure guiding pipeline system, close all valves, and prepare to put into operation. The above is the whole content of this article.
