Does the vortex flowmeter need temperature and pressure compensation when measuring steam?

 Does the vortex flowmeter need PTC when measuring steam?

Vortex flow meter generally only need to compensate for one of pressure or temperature when measuring saturated steam. Because the density of saturated steam corresponds to the pressure and temperature of saturated steam, vortex flow meter measure steam Just measure a pressure or temperature.

There are generally two options for temperature and pressure compensation vortex flow meter. One is an intelligent vortex flow meter with integrated display of temperature and pressure compensation. One is a split vortex flow meter, which is a simple vortex sensor, temperature sensor, pressure transmitter, and flow totalizer.

But if it is to measure superheated steam, it is necessary to install a temperature and pressure compensation vortex flowmeter. Because the density of superheated steam is related to temperature and pressure. In order to measure accurately, the vortex flowmeter should choose temperature and pressure compensation vortex flowmeter.

The intelligent vortex flowmeter has its own temperature and pressure compensation. The converter of the vortex flowmeter processes and converts the volume temperature, flow, and pressure signals measured by the vortex sensor, and displays them on site. The split structure is a simple vortex sensor, temperature sensor, pressure transmitter, flow totalizer, and four combined flowmeters, so as to achieve the purpose of measurement.

Sometimes the manufacturer will set a coefficient for the vortex flowmeter to measure steam according to the actual requirements of the user, but the measurement accuracy of the corresponding vortex flowmeter will not be too high.
