Gear flow sensor VHM Series

The positive displacement gear flow meters of the VHM series are based on the meshing gear principle and are suitable for a wide variety of liquids, especially liquids with high abrasiveness and poor lubricity. Each tooth generates an impulse by recognition of the gear rotation by a non-contact detection system according to the carrier frequency principle. The VHM flow meters are available with single, double or quadruple resolution and signal-output with NPN- or PNP-switching mode. Additionally, the flow meters are dead spaced optimized for (easy flushing) use in the paint industry and for paint spraying systems.
