Comparison of Vortex Flowmeter and Differential Pressure Flowmeter for Steam Measurement

Flow meter /

In industrial settings, steam flow measurement is crucial for maintaining process efficiency, energy conservation, and system safety. Two widely used methods for measuring steam flow are the vortex flowmeter and the differential pressure (DP) flowmeter. Each method has its advantages and disadvantages, making them suitable for different scenarios. Below is a detailed comparison of both […]

How to Determine if a Differential Pressure Transmitter is Operating Normally in the Field

Pressure Transmitter /

Answer: Since the common faults in differential pressure transmitters are zero-point drift and blockage of the pressure guide tube, calibration of the scale point by point is rarely performed in the field. Instead, the zero-point and trend of changes are checked, as follows: Zero-point check: Close the positive and negative pressure shut-off valves. Open the
