dBMACH3
high accuracy open channel flow transducer.
Featuring unique sun and submergence shields, the dBMACH3 transducer is designed specifically for open channel flow applications. dBMACH3 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. One of the critical factors affecting ultrasonic accuracy is the measurement distance and air temperature, so by minimising this distance, accuracy is maximised. Operating at 125kHz frequency the transducer provides a resulting high resolution accuracy. Essential in open channel flow applications. This dBMACH3 is used with Ultra 3 or 5 and TWIN when in open channel flow mode.

FlowCERT
the most accurate ultrasonic open channel flow system available anywhere.
Pulsar's FlowCERT system gives you everything you need for the industry's highest accuracy non-contacting ultrasonic measurement of open channel flows. Designed for flumes and weirs, FlowCERT gives temperature-independent, reliable measurement and logging facilities. It includes five alarm/control relay plus 4-20mA output, data logging, digital input with the ability to accept a Speedy velocity sensor input for non PMD (area x velocity) applications. Programming is a simple menu driven process.
In recent MCERTS tests, FlowCERT with DUET was found to be the MOST ACCURATE open channel combination tested. Not only that, but Pulsar's option, FlowCERT Lite, featuring a dBMACH3 transducer, also passed the Class 1 test.
