The established vane technology has proven itself a million times worldwide for measuring and monitoring the flow of different mediums in pipelines. Flowmeters/monitors work with this  proven principle and offer many benefits. The heart of the new vane is an embedded ring magnet; it is hermetically sealed from the flow medium. It transfers, in a non-contacting manner, the  rotary motion of the vane to a Hall sensor attached to the case (in order to save space).

This converts the rotary motion to a frequency signal that is proportional to the flow rate. The downstream evaluating electronics can output this signal to a display, convert it to (0(4)-20 mA, 0-10 V) analogue signal, or count it. It may also be used to switch with up to two limit contacts. The ready and control states of the limit value relay are indicated by LEDs. The modular design of flow monitors and measuring instruments is a system that can be universally applied; it is reasonably priced; and requires minimum space when in service.

Very precise measurement results can be achieved, under tough operating conditions along with the electronics. The system is assembled with the electronics and delivered ready for service. The electronics are adjusted and tuned for use with the sensor. When retrofitted for other measuring ranges, the system  may be re-adjusted with a similar device at any time.
