The customer wanted to perform a water flow survey on a 1.5 mile long mains water pipeline at 5 different locations to ensure that there was no water leakage and that the flowrate was as per the design to meet the local demand.

This turned out to be a successful non-invasive water flow test on a 51″ (1,300mm) GRP pipeline using our UF801 Portable Clamp-on Flow Meter without any pipe cutting or drilling.

We successfully performed this water flow survey using our clamp-on flow metering technology without any alterations to the pipe line or system shutdown. Customer needed an average accuracy of +/-5% but our equipment exceeded the expectations and delivered an average accuracy of +/-2%. Needless to say, it was possible to further enhance the accuracy of the readings up to +/- 0.5 – 1% on such large pipe diameter by utilizing two flow channels on our UF801 flowmeter. By doing so, it would be possible to average flow velocities along to different planes across the pipe’s cross-section to achieve a more stable and accurate flow reading.
