The KOBOLD TUR turbine flow meter serves applications involving the need to measure, control and regulate flowing, water-like liquids with a viscosity of 8 cSt or lower. The use of highly chemically resistant materials such as PVC or PVDF in the construction of TUR allows them to withstand acids, lyes and other aggressive media commonly found in the chemical industry. TUR flow meters may be installed in any desired orientation provided care is taken to keep the flow meter full of liquid. The motion of the media through the housing causes rotation of the turbine, which is detected by an external proximity sensor. Turbine rotation is linear with respect to flow over a range comprising approximately 90% of the upper range of this flow meter. An optional display and control module converts the impulse signal into a displayed number or control output (relay closure or current loop).
