turbine flow meter / for liquids / in-line

The SIKA Type VTH 15 Insertion turbines provide a reliable method for measuring flow, and water dosing for water based mixtures, making them well suited for various applications such as blocks and valves in machine and plant engineering or water treatment equipment. These units operate by splitting the flow of liquid into smaller jets, using guiding blades, that then impact the rotor evenly from several directions. The rotation of the rotors is measured via sensors using the magnetic Hall effect, and converted into an electric frequency. The STI version of the turbine is equipped with stainless steel pins in the rotor, and uses inductive proximity switch to detect rotation. Both methods produce a square-wave signal (or frequency signal proportional to the flow). As the inflow of liquid is uniformly distributed across the bearing, the impact forces are largely mutually canceled, reducing wear to the minimum.
