In the first article of this 2-part series, we showed you how a Differential Pressure Transmitter is used to measure the flow rate. This second part of our series will take you through the process of calibration and checking the output accuracy of a differential pressure flow transmitter. If...
DP flowmeters, however, are different because of the complexity of the measurement. DP flowmeters require some type of constriction in the flowstream, created by a primary element. They require a DP transmitter to provide a reading of the difference in line pressure upstream and downstream from ...
This dp flow transmitter output calculator uses the following formula to calculate the output over a SqRt 4-20mA range: Linear mA out = 4 + (16 x ((Rdg – Low Limit) / (High Limit – Low Limit))) Parameters Unit Enter the unit used for measuring differential pressure, e.g. mbar, ...
