The DUET is a unique product to Pulsar Measurement and features a patented approach when it comes to addressing the issue of accuracy for flow measurement. Both transducers fire together, by continuously monitoring the phase difference of the echoes, and because the distance between the transducer faces is known and constant, the speed of sound is continuously updated in real-time for the process. As a result, the accuracy and stability of measurement readings are exceptional. The DUET Transducer System must be combined with the FlowCERT controller and benefits from MCERT Certification. This means that Pulsar Measurement meets the framework of standards set out by the Environment Agency to ensure that everyone involved in the monitoring of liquid flow is working towards the same standards and providing accurate flow data.
