Friction flowmeter with improved software |
摘要 |
A method in a pressure transmitter and a pressure transmitter for determining a mass flow rate of a fluid in a conduit measure a differential pressure between two points in the fluid, where the conduit has a substantially constant cross-sectional area between the two points. In one aspect, the mass flow rate is calculated by multiplying the square-root of the differential pressure by a mass flow constant.
