Coriolis Flowmeters

The mass flowmeter uses the Coriolis principle of operation in order to measure the mass flow rate. Accordingly, density and temperature are simultaneously monitored, and the flow rate is calculated considering these parameters. As a result, the flow rate is made available either through a directly mounted specific transmitter, or through a dedicated remote transmission configuration.
The device can be used for measuring the flow rate in almost all sorts of liquid and gaseous fluids and has been especially designed to work with standard applications. It is used in diverse industrial fields. It is also used at accurate dosage operations, as well as during loading – unloading processes.
Approvals for custody transport service (tax assessment) are available.
