Can the flow meter be involved in pressure test?
Under normal circumstances, design flow timing, we must consider the use of good products, the pressure is not (below the maximum use pressure) circumstances, the problem is not large.
Yes, but to distinguish the pressure is low, medium pressure, low, medium pressure can be, high pressure is best not to participate, because the pressure of the test pressure is high and the use of pressure, may cause the flow meter error increases.
It is better not to, because when you test the pressure, the flow meter will start metering, and the pressure is faster than the flowmeter flow range, may cause damage to your flowmeter, affect the accuracy of measurement.
After buying the correct flow meter, it is better to look at the instructions of the flowmeter first and see the important points of attention. If the correct installation does not affect the use of the meter, it will cause the measurement to be inaccurate. Pressure testing under the maximum operating pressure of the flowmeter does not, of course, cause damage to the instrument.
As the user must first tell the seller, use their own in what occasions, including what to measure the fluid medium, is water, steam (saturated steam or superheated steam), compressed air or other, what is the maximum pressure, temperature and flow, what is the use of pipe diameter? Also, if the user has any special use requirements, should also be told to suppliers, these parameters must be told to the supplier, otherwise there may be the purchase of things can not be used.
