Possible areas of application

SIKA VTY OEM turbines were specifically designed for potable water applications. Application areas include:

• In-house potable water supply
• Agriculture
• Food industry

Description

Measuring principle
The liquid flowing into the turbine flow sensor is split into individual jets by the guiding blade. These jets hit the rotor evenly from different directions, setting the rotor in motion. The rotation speed of the rotor is then converted to an electrical pulse signal (frequency): The rotors are fitted with magnets and a Hall effect sensor detects the rotation of the rotor. The VTI series has stainless steel pins in the rotor. An inductive proximity switch detects the rotor rotation. In both cases, 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 tungsten carbide - also guarantee an exceptionally long endurance.

• Sapphire-supported turbine for long durability, for OEM
• Turbine body made of brass or glass-fibre reinforced plastic, turbine internals made of glass-fibre reinforced plastic
• Wide measuring span (1:30)
• Flow proportional frequency output signal
• Various fitting positions
• Practically independent from flow straighteners
• Insensitive against water hammers
