What is the temperature and pressure compensation of a steam vortex flowmeter?
The measurement is different, according to the temperature parameters near the pipe flowmeter pressure, temperature meter and other parameters of the steam flowmeter, pressure to do comparison, find a fault, if the pressure and temperature are normal, we consider the problem of the scene can not determine the flowmeter, flow metering station do, to test, finally find the problem.
Steam is divided into saturated steam and superheated steam. Saturated steam is compensated by temperature or pressure, and superheated steam must be compensated simultaneously with temperature and pressure.In the steam metering system, the vortex flowmeter measures the volume of the steam flow, the temperature sensor and the pressure transmitter respectively measure the temperature and pressure, and the integrator accepts the signals of the three.
Steam flowmeters are generally divided into mass flow meters and heat flow meters. But either way, it must be compensated by temperature and pressure. Temperature and pressure compensation is the main steam density, volume flow meter measuring main steam, the two is obtained from multiplying the steam quality flow, the calculation process is generally implemented by integrating instrument or intelligent amplifier.
