VTY 15 Turbine Flow Sensor

The SIKA VTY 15 turbine flow sensor gives you precise and robust products to measure flow rates or total flows, for water and water mixtures. The VTY 15 turbine flow sensor is specially developed for installation in electrical heat interface units (HIU). The sensors are particularly suitable for use in, e.g. dosing systems, heaters, coolers or temperature control units.

The liquid flowing into the turbine flow sensor is split into individual jets by the flow straightener. These jets hit the rotor evenly, setting the rotor in motion. The rotation speed of the rotor is then converted to an electrical pulse signal (frequency): The rotor is fitted with magnets, and a Hall effect sensor detects the rotation of the rotor.

A flow-proportional frequency signal (square-wave signal) is made available. Given the uniform inflow to the bearing, the forces largely cancel themselves out and wear reduced to a minimum. The sturdy bearing materials – sapphire and hard metal – also guarantee an exceptionally long endurance.
