POA Correlation Wedge Sensor

• Ultrasonic Cross Correlation with digital pattern detection (flow velocity)
• Ultrasonic transit time (level measurement)
• Piezo-resistive pressure measurement (level measurement)

IP 68

max. 4 bar (combi sensor with pressure cell max. 1 bar)

10 / 15 / 20 / 30 / 50 / 100 m pre-configured, can be extended upon request;

a pressure compensation element is required if cables longer than 30 m are used with sensors featuring an integrated pressure measurement cell. The compensation element can be used also to connect the extension.

• Cable end pre-configured for connection to NivuFlow 750
• Cable end with plug for connection to NivuFlow Mobile 750
• Cable end with plug and pressure compensation element (sensors with pressure measurement cell only) for connection to NivuFlow Mobile 750

Polyurethane, stainless steel 1.4571, PPO GF30, PA
