Pulsarís MCERTS Success: Still the Most Accurate OCM In the World

Posted: Friday 30th January 2015

Pulsar Process Measurementís FlowCERT non-contacting ultrasonic open channel flow measurement systems have each achieved the highest Class 1 level during re-certification to the latest update to the MCERTs certification process. FlowCERT with Pulsarís unique DUET transducer array has been again shown to be the worldís most accurate ultrasonic Open Channel Flow measurement system.

Pulsarís FlowCERT Lite and FlowCERT with DUET are dedicated open channel flow (OCM) monitors, both of which make use of Pulsarís world-leading DATEM echo processing software to achieve rock-solid measurement. FlowCERT Lite uses Pulsarís dB3 transducer, with its high-frequency crystal array for high resolution in the measurement, and an external temperature sensor. DUET, designed specifically to be used with FlowCERT, is Pulsarís unique twin-transducer array that integrates the signals from the two separate sources to render the system almost completely impervious to any variation in the speed of sound within the air column above within the channel.

The latest, more rigorous, version of the MCERTS tests include a simulation of varying solar radiation, which can have a significant effect on level measurement instrumentation of all types. Both FlowCERT and FlowCERT with DUET achieved Class 1 passes, the highest level of certification within the MCERTS standard. FlowCERT with DUET was measured with a ĎCombined Performance Characteristicí of 0.044% error, well within the Class 1 standard of 0.2% error and the highest accuracy of any manufacturerís instrument tested.
