Hi all,
this questin is not realted with PLC. we are trying to measure flow rate. For that we are using orifice plate as sensor. I t will give us volumetric flow rate. But i want this flow in temrs of mass flow rate. For this it is necessary to multiply the volumetric flow rate that we are getting by density. Now as flow pressure and temperature varies, then its denisty varies. My question is that, how the compensation for the temp and pressure is achieved for the density? This formula i will going to use as algorithn for the controller.
If anybody knows the formula or reference please help me.
regards,
prashant
