Possible areas of application
Push-in flow sensors of the type VTY10 were specially developed for the installation in fittings and feature an easy and space-saving system integration. Typical applications for these flow sensors are:
- Tap water detection
- Water treatment
- Leak detection
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 is reduced to a minimum. The extremely hard bearing materials - sapphire and hard metal - also guarantee an exceptionally long endurance.
In general, push-in flow sensors consist of three components: push-in turbine, Hall effect-sensor and adapter sleeve for Hall effect sensor. This three-part construction is the key for the space-saving installation in e.g. filter heads and allows the separate installation of hydraulic and electrical components. A high quality sapphire bearing guarantees a long durability of the measuring system and allows the measurement of low flow rates from one litre per minute due to low start-up velocities.
- Low deviation in mass production, fixed pulse rate
- High measuring accuracy
- Low wear and extremely long durability due to high quality bearing
- Compact dimensions
- Proven in numerous mass production applications
