Description

VSE VHM Gear Flow Meter 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. Each tooth generates a pulse when it passes the contactless signal pick-up system in accordance with the carrier frequency principle.

VSE has developed a high-precision flow meter for a wide variety of liquids, especially liquids with high abrasiveness and poor lubricity. Applications include the chemical, petrochemical, pharmaceutical, and cosmetic industries, two-component mixers, paints, and aviation. VHM flow meters are dead space optimized for use in the paint industry and for paint spraying systems (easy flushing).

VSE VHM Gear Flow Meter 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, output with NPN- or PNP-switching mode. Signal pick-ups with -certification (EEx ia llC T6… T4) and signal pick-ups with a fiber optic output are applicable for hazardous locations.
