Thermal Flow Measurement Technology
Rheotherm instruments use thermal mass flow measurement technology to directly measure mass flow independent of pressure and temperature changes. With no moving parts, these instruments deliver stable, repeatable measurements with low pressure drop and minimal maintenance.
Rheotherm and RheoVac instruments are available with integral or remote electronics and support a wide range of industrial output signals and communication protocols.
