What is flow compensation?
The flow compensation equation requires the determination of the fluid density at actual conditions (a). If the fluid is an ideal gas, then the Ideal Gas Equation can be used to obtain the actual density: P * V = n * R * T (5) where: P = absolute pressure (psia)
How do you calculate temperature compensation?
This temperature compensation is calculated by applying an industry standard 2% to the conductivity value for every degree away from 25°C the temperature reads.
What is compensated steam flow?
The purpose of steam flow meter with temperature and pressure compensation is for when the volume deviate the actual flow compensation will correct the result well. Steam in gas status, the density varies with the changes of temperature and pressure itself. If don't have the compensation will cause a huge error.
What is a compensated flow meter?
Compensated flowmeters work with a variable orifice and fixed pressure. They read back pressure, and take into account resistance changes downstream from the needle valve. If pressure exceeds 50 psig downstream, flow ceases. The types can be distinguished by their response when gas starts to flow.
