8071 Positive Displacement Low Flow Sensor

Brand: Burkert Fluid Control Systems
Does not ship to Virginia, United States

This positive displacement sensor is specially designed for measurement or batch control of highly viscous fluids like glue, honey or oil. It allows an easy connection to transmitters like type 8025 and 8619 for more functionality. 

The design of this low flow sensor is based on the oval rotor principle. This has proven to be a reliable and highly accurate volumetric method of measuring flow. Exceptional repeatability and high accuracy over a wide range of viscosities and flow rates are features of that design. 

The low pressure drop and high pressure rating make it suitable for both gravity and pump (in-line) applications. All sensors provide Open Collector NPN frequency output and frequency output on Reed contact via 1 meter 5-wire cable with open ends.
