Remote display vortex flow meter with compensation
Normally, vortex flow meter is used to measure steam.
It could have tempreature and pressure sensors for compensation.
And for integral type vortex flow meter, they are built-in sensors.
If it's remote type vortex flow meter, the temperature and pressure should be separated.
And output from flow meter, temperature sensor, pressure sensor will be sent to flow totalizer.
The totalizer could process the compensation calculation.
