PEL Turbine Wheel Flowmeter

Brand: KOBOLD Instruments, Inc.

The sensor principle based on a Pelton water wheel is remarkable for its high reliability - proven over more than ten years of service.

This flowmeter is to be found in applications in a variety of plants, where they are mainly used for measuring of negligible volumetric flow rates of media such as fuels, distilled water, or hot greases.

The sensors satisfy almost all industrial requirements with temperature limits of 135° C and nominal pressures up to 345 bar (higher pressures upon request).

Only V4A Supra stainless steel (material no. 1.4571) is used for metallic parts. Swiss precision sapphire bearings ensure long service life and reliability.
