The flow rate measured by the differential pressure transmitter always fluctuates. I want to modify the damping time of the transmitter, but I dont know the damping time Adjusting the damping time does not actually solve the problem. Do you use a separate differential pressure transmitter to measure the flow rate? Jian Nian San Chang suggests that you use a flow meter to measure the flow rate. If the working conditions permit, you can use an orifice plate, so that your differential pressure transmitter can still be used. Note that the straight pipe section must be sufficient, otherwise the flow rate will still fluctuate. Is your differential pressure transmitter located closer to the pump or elbow? Changing the position may be better.

2. What does the damping coefficient of a gas flowmeter mean? How to calculate its traffic? The damping coefficient of the flowmeter for measuring Wu Xun gas refers to a set of corresponding relationships between damping time and flow rate, which plays a role in smoothing the display of flow rate. The function of damping coefficient: In flow meters, damping coefficient is mainly used to smoothly display flow values, avoid frequent changes in display values caused by measurement fluctuations, and thus improve the stability and readability of readings. Application example of damping coefficient: If the damping time is 5 seconds, the flow display value is the average of the flow measurement values in the past 5 seconds. This means that during these 5 seconds, regardless of how the flow fluctuates, the displayed value will remain at the average of these 5 seconds, providing a relatively stable reading. The method of calculating flow rate: Given the known damping coefficient, the calculation of flow rate is usually not directly completed through the damping coefficient, but first measured by a flow meter to obtain the instantaneous flow rate value. Then, based on the damping time, calculate the average of all instantaneous flow values over a certain period of time, which is the displayed flow value after damping. It should be noted that the specific calculation method may vary depending on the type and manufacturer of the Bi Jian flowmeter. Therefore, in practical applications, reference should be made to the flowmeters user manual or technical information provided by the manufacturer. In summary, the damping coefficient is mainly used in flow meters to smoothly display flow values and improve the stability of readings. The calculation of flow rate, on the other hand, is based on the instantaneous flow value measured by a flow meter and combined with damping time to calculate the average value.
