8081 Flowmeter for Water Continuous Measurement
Brand: Burkert Fluid Control Systems
The Type 8081 ultrasonic flowmeter is intended for the measurement of water flows which may be slightly charged with contaminants.
It consists of an electronic module and a brass fitting with a built-in measuring tube. It enables a control loop to be established.
The electrical connection is made via an 5-pin M12 fixed connector.
Features- Ultrasonic flowmeter using transit time method
- Dynamic range ≥ 1:250
- Low pressure drop
- No flow-settling section necessary in the inlet and/or outlet
