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.
VSE have developed a high precision flow meter for a wide variety of liquids, especially liquids with high abrasiveness and poor lubricity. Applications include: chemical, petrochemical, pharmaceutical and cosmetic industry, two-component mixers, paints, aviation. VHM flow meters are dead space optimised for use in the paint industry and for paint spraying systems (easy flushing).
Gear Flow Meter VHM Series
They are positive displacement units based on the meshing gear principle. Each tooth generates an impulse by recognition of the gear rotation by a non-contact detection system according to the carrier frequency principle. VHM flow meters are available with single, double or quadruple resolution, signal-output with NPN- or PNP- switching mode. Signal pick-ups with -certification (EEx ia llC T6… T4) and signal pick-ups with a fibre optic output are applicable for hazardous locations.
