Whether it is necessary to have temperature and pressure compensation when measuring steam with vortex flowmeter
2021-05-25
Vortex flowmeter generally only needs to compensate one of the pressure or temperature when measuring saturated steam, vortex flowmeter because the density of saturated steam and the pressure and temperature of saturated steam are corresponding, vortex flowmeter measurement of steam only needs to measure a pressure or temperature.
There are generally two kinds of temperature and pressure compensated vortex flowmeters. One is the intelligent vortex flowmeter with integrated display of temperature and pressure compensation. One is a split vortex flowmeter, which is a simple vortex sensor, temperature sensor, pressure transmitter, flow integrator
However, if it is to measure superheated steam, it is necessary to install a temperature-pressure compensated vortex flowmeter. Because the density of superheated steam is related to temperature and pressure. In order to measure accurately, the vortex flowmeter should choose the temperature and pressure compensation vortex flowmeter.
Intelligent vortex flowmeter, with temperature and pressure compensation, the converter of vortex flowmeter will process and convert the volume temperature, flow rate and pressure signal measured by the vortex sensor, and display it in one place. The split structure is a simple vortex sensor, temperature sensor, pressure transmitter, flow integrator, four combined flowmeters, so as to achieve the purpose of measurement.
Aister manufacturers will also set a coefficient to measure steam according to the actual requirements of users, but the measurement accuracy of the corresponding vortex flowmeter will not be too high.
