Low series dispersion, fixed pulse rate
high measuring accuracy
low wear and extremely long service life due to high-quality bearings
compact dimensions, proven in numerous large series applications
Push-in flow sensors of type VTY20 have been specially developed for installation in fittings and are characterized by simple and space-saving system integration. Typical applications for these flow sensors are in the areas of:
• potable water tap detection
• water treatment
• leakage detection
The push-in flow sensor consists of two components: a turbine push-in module and a Hall effect sensor. This design is the key to space-saving installation. A high-quality sapphire bearing ensures a long service life of the measuring system and enables the measurement of small flow rates from one litre per minute due to low start-up speeds
• low series dispersion, fixed pulse rate
• high measuring accuracy
• low wear and extremely long service life due to high-quality bearings
• compact dimensions
• tested in numerous large series applications
The liquid flowing into the turbine flow sensor is divided into partial jets by the blading. These hit the rotor uniformly from different directions and cause it to rotate. The speed of the rotor is now converted into an electrical pulse signal (frequency): The rotor is equipped with magnets, a Hall effect sensor detects the rotational movement.
A flow proportional frequency signal (square wave signal) is available. Due to the uniform flow to the bearing, the forces largely cancel each other out and wear is reduced to a minimum.
