SIKA OEM turbine flowmeter/flow sensor for drinking water applications

2019-11-08 17:14:19

During the development phase, we provide technical advice with knowledge about application and collaboration. Flexibly adapt to existing standards, design products to meet customers' needs and their applications, and cooperate closely in quality assurance and product improvement to ensure optimal results. Able to combine a variety of sensors or functions, the SIKA turbine flow sensor has an accurate and robust design that can be used to measure the flow rate or total flow rate of water and water mixtures

Possible areas of application:

Turbine flow sensors of the series VTY were specially developed for the use in potable water mass production applications.
Sensors of the series VTY are used among others for the measurement of tap water.


Measuring principle
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.


Low wear and extremely long durability due to high quality bearing

Practically no deviation in mass production due to fixed pulse rate

Wide measuring span (up to 1:60)

Insensitive against water hammers

Proven in numerous mass production applications

High measuring accuracy, mostly independent of fitting position due to integrated flow straightener
