About
Prowirl
All vortex
flowmeters measure the volumetric flow of liquids, gases and steam, but are
often particularly favored for steam measurement. When measuring steam mass
or energy content, a vortex flowmeter is paired with a pressure or
temperature sensor, and a flow computer. Endress+Hauser's
Prowirl family of products include vortex flowmeters, transmitters, and
sensors. Flowmeter and transmitter models available are 72F, 72W, 73F, and
73W. The F versions are flanged and the W versions are for water. The 72's
are for universal volumetric measurement of flowing gases, steam and
liquids. The 73's include temperature measurement for calculating mass
flow, and, combined with a steam computer, the 73 gives the user
direct BTU readings. Prowirls
are available in standard or explosion-proof models, and in compact or
remote versions. Transmitters of both model groups output volume and mass
flow. Additionally, the Prowirl 73's integrated flow computer
calculates pressure and temperature-compensated mass flow of
gases or superheated steam. Endress+Hauser
offers sensors in the Prowirl F and the Prowirl W models. Both can
withstand process temperatures from -200...+400 °C (-330...+750 °F). The
Prowirl W can withstand pressure ratings up to PN 40 (Cl 300), and the
Prowirl F can withstand pressure ratings up to PN 160 (Cl 600), or to PN
250 (Cl 1500), optionally.
