发明名称 FRICTION FLOWMETER WITH IMPROVED SOFTWARE
摘要 A method in a pressure transmitter (144) and a pressure transmitter (144) for determining a mass flow rate of a fluid in a conduit (132) measure a differential pressure between two points (136, 138) in the fluid, where the conduit (132) 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.
