Basics and practice

Fieldbus & HART


Sensyflow FMT500-IG is a thermal mass flowmeter for gases. The measuring principle (hot-film  anemometer) allows the direct determination of mass flow and gas temperature. Taking the standard density of the gases into consideration, the standard volume flow rate can be displayed without additional pressure and temperature compensation.
The integral mount design of the Sensyflow FMT500-IG metering system comprises a transmitter, flowmeter sensor and a pipe component. In the remote mount design the flowmeter sensor and the transmitter are connected via cable.
The pipe component is available in various designs. It is also possible to install the flowmeter sensor directly in square ducts or pipes with any diameter via a weld-on adapter.
