VHM gear flow meter

Our VHM series was developed in particular for the high precision measurement of abrasive and poorly lubricating media. The gear flow meters work in accordance with the displacement principle and are suitable for a variety of fluids.

Each tooth generates a pulse when it passes the contactless signal pick-up system in accordance with the carrier frequency principle. The VHM flow meters are available with single, double and quad resolution and signal output with NPN or PNP modes.

The flow meters are also dead space-optimised for (flush-friendly) usage in the painting industry.
