High Accuracy Open Channel Flow Sensor

The Pulsar Measurement dBMACH3 is a highly accurate ultrasonic level transducer, which has been designed specifically for open channel flow applications. It is the first ultrasonic transducer with zero effective blanking distance beyond the nose cone, allowing it to be sited as little as a few mm from the high-flow level, which ensures a high level of accuracy. Operating at 125kHz frequency the transducer also provides a high resolution, which is essential in open channel flow and flume applications. The dBMACH3 is used with the Ultra 4, Ultra 5, or TWIN controllers, when in open channel flow mode. Or can be paired with FlowCERT all of which provide a typical accuracy of ± 1 mm (0.04 in).
