What are the causes of the electromagnetic flowmeter error?
（
1)
Liquid not full.

When the pipe is a small amount of gas, can make the results of measurement are usually deviated from the actual value, cause small error;

When there is a lot of gas, the measured value is not stable, will appear.

More flow meter manufacturers choose model price quote you are welcome to inquire, the following was the cause of electromagnetic flow meter scale error factors what article details.

What are the causes of the electromagnetic flowmeter error?
（
1)
Liquid not full.

When the pipe is a small amount of gas, can make the results of measurement are usually deviated from the actual value, cause small error;

When there is a lot of gas, then there will be a measured value is not stable, output and the measured value is not as a correct result.
（
2)
Measured in the liquid containing solids.

It leads to be defiled, covered electrode or electrode surface lining, reduce the circulation area, flow value decreases.

If the sediments with conductive material, traffic signals are likely to be short circuit, make the instrument malfunction.
（
3)
Incorrect ring electrode or ground.

Contact electrode and the flow medium, the medium of the electrochemical reaction will produce polarization voltage.

Traffic signal electrodes can reliable detection, the performance of the flow meter is very important.

Grounding rings have the electrical connection with the media, through the grounding line and zero potential through.

When connected to the sensor of the process piping for plastic or with insulation coating line, must install grounding loop, otherwise it will cause the instrument can't work normally.

There are many kinds of, the material of electrode and ground ring when the choice must pay attention.

The flow measurement of electromagnetic flowmeter is a widely used instrument, used in the measurement of sewage wastewater, cost-effective.

But due to improper selection, installation or use will make the error of the measured results, even damage the instrument.

Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

Abstract: The information on the processing method of no signal output of the steam flow meter is provided by the excellent manufacturers of flow meters and flow meters. Steam flowmeter without signal output processing method 1. Confirm that there is flow 2. Monitor the power supply, the voltage between the positive and negative terminals must be between 10.5-50VDC A. If the voltage is zero, check the power supply fuse B. If the voltage is very low but not Zero, the flowmeter can be loaded. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on the processing method of no signal output of steam flowmeters. Steam flowmeter without signal output processing method 1. Confirm that there is flow 2. Monitor the power supply, the voltage between the positive and negative terminals must be between 10.5-50VDC A. If the voltage is zero, check the power supply fuse B. If the voltage is very low but not Zero, the flowmeter may be loaded with power. Open the field terminal cover, disconnect the positive and negative poles, measure the supply voltage, if the voltage is normal, the power supply circuit at this point is normal, reconnect the positive and negative poles to C, open the electronic module isolation cover, and connect the red , The yellow and green wires are disconnected, measure the voltage between the red wire and the green wire, if the voltage is normal, the electronic module is damaged, replace the electronic module D. If the voltage is still low, the shell/terminal is damaged, replace the shell or return the meter Go to Foxboro for repair 3. Check the 4-20mA output circuit A. The 4-20mA circuit can be detected by the test socket on the field output terminal board, which generates a voltage signal of 0.1-0.5 corresponding to a current signal of 4-20mA. Make sure switch J is off as the test socket is not available in pulse output mode B. Increase the flow to confirm that the meter is not operating below the low flow blocking range.

Abstract: The information on the matters needing attention when measuring the v-cone flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. V-cone flowmeter, also known as inner cone flowmeter, V-cone, and cone flowmeter, is a new type of differential pressure flowmeter with technology. It has the same basic principle as other types of differential pressure flowmeters and is based on sealed pipes. The principle of energy conservation in the SK series V-cone flowmeter. More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the article details of the precautions when measuring with v-cone flowmeter. V-cone flowmeter, also known as inner cone flowmeter, V-cone, and cone flowmeter, is a new type of differential pressure flowmeter with technology. It has the same basic principle as other types of differential pressure flowmeters and is based on sealed pipes. Based on the principle of energy conservation in the SK series, the unique design of the SK series V-cone flowmeter expands the flow measurement range and avoids some of the limitations of traditional differential pressure flowmeters, resulting in better performance. SK series V-cone flowmeter is to hang a conical cut-off piece in the center of the pipeline. The conical piece obstructs the flow of the medium and reshapes the flow rate curve. The measuring medium includes water, steam, air, natural gas, nitrogen, coke oven gas and organic gas. Media conditions can range from cryogenic to supercritical. The maximum working temperature is 450℃, and the maximum pressure is 25Mpa. Cone flowmeters have a wide range of applications, but in many fields, the application of gas is the most common. In gas measurement, pay attention to several situations, which will affect the measurement results. 1. Pay attention to the influence of impurities contained in the gas We all know that the composition of gas is very complex. Under long-term use, the diameter of the cone will directly affect the measurement accuracy due to the adhesion of impurities. Therefore, the user should pay more attention to the use of the instrument, and clean and maintain it in time. 2. Pay attention to the error caused by the secondary instrument, the error of the differential pressure transmitter, pressure transmitter, flow totalizer and other secondary instruments, as well as the leakage of the connection between them, joint conversion, etc., and also affect the V-cone flow rate. The accuracy of the meter has the most direct impact and should be given great attention. 3. Pay attention to the influence of gas density changes. It can be seen from the flow formula that density and differential pressure are in the same important position. Therefore, if the density measurement is not accurate, even if the differential pressure measurement is very accurate, then the entire measurement system has to be to high precision. During normal calculation, the density value is usually fixed. This has little impact on a single gas source, but if it is mixed with some water, liquefied petroleum gas and other gas sources, the v-cone flowmeter will measure The error will be quite large. To use the V-cone flowmeter to measure gas, it is not necessary to install it to see the flow rate. During use, pay attention to observe and record the flow change and check the operation of the instrument. If there is a problem with the instrument data, the instrument should be overhauled according to the specific problem. The above is the whole content of this article.
