How to determine whether a orifice plate flow meter is functioning properly
Thread Content
There are two orifice flow meters used to measure steam, and the flow rates calculated by them differ somewhat. How can one determine which meter provides an accurate reading?
It’s hard to say for sure, but an external inspection can be carried out first. Check whether there are any leaks or blockages in the pressure guiding pipes, then zero the three-valve group transmitter, verify that the parameters of the integrator are set correctly, and check if the connection wires are loose； If the difference remains large, the only option is to remove the flow meter for calibration...
In addition to what was mentioned above, it is also necessary to check the liquid level in the condensate tank, as well as the installation locations of the two flow meters, the distance over which they transmit data, and whether temperature and pressure compensation is available
