The flow transmitters of the OMNIPLUS-VHZ series are suitable for liquid, viscous, lubricating media (e.g. lubricating oil). The measurement is carried out volumetrically by two interlocking gears, which rotate in opposite directions driven by the flowing medium. Due to the volumetric measuring method, the devices work almost viscosity-independent.
A sensor located outside the flow chamber detects the tooth flanks and generates a flow-proportional frequency signal. A pulse thus corresponds to a certain measuring volume. There are no magnets in the flow chamber. The devices can be operated bi-directionally. The flow direction is detected by the electronics and shown in the display (not at nominal diameter DN8!). The integrated totals counter works adding or subtracting depending on the flow direction.
The integrated electronics have an LCD display as well as an analog output and two switching outputs and are easily configurable by the user.
The bodies of the devices are made of aluminum or stainless steel.
