The basic system in the VTR series comprises a rotor, the housing body and a measurement pick-up. Thanks to the specific internal diameter, the speed of the turbines is directly proportional to the flow. All flow meters in the VTR series are individually calibrated. A wide range of electronic evaluation and display units are also available to our customers.

Turbine flow meters are precise and reliable measuring instruments, designed for a wide range of applications. Even under the most difficult application conditions in the oil, petrochemical and chemical industries as well as in other industrial sectors, the sensors of the VTR series can be installed.

The range of nominal widths spans from 10 mm to 500 mm for the flange version as well as from 10 mm to 50 mm for the version with threaded connection. All VTR flow meters are individually calibrated. A wide range of electronic evaluation and display devices is available.
