Why have your flow-meter verified?
Your flow-meter was likely to have been setup and verified by a fully qualified Engineer. However, things can change; so how can you be sure that the flow system will continue to give accurate data? Flow regimes can be altered, maintenance can become lapse, meters can go out of calibration, sensors get moved, or start to fail. This can have a major impact on accuracy.
In order to limit the effect of such errors over a long period, the flow-meter verification service has been introduced. The service gives assurance that accurate flow data is being generated and recorded.
An early warning of flow measurement problems can enable remedial action to be taken quickly and further costs from inaccurate readings can be avoided.

What's involved in a Flow-meter verification?
Your flow-meter will be inspected by a fully qualified Engineer. The flow system will be measured-up and the flow meter-interrogated.
For closed pipe systems, an evaluation of the performance of the flow system will be undertaken using a clamp-on flow meter.
For closed and open channel systems, the primary measurement devise will be measured up and compared to Environmental Flow Ltd software. This will provide a flow comparison and an assessment of the conditions within the flow meter system, in order to ensure that they are suitable for flow-measurement. Any variations to the site data are logged and if the variations violate the appropriate BS or ISO Standards then recommendations are made to improve the accuracy of the flow-meter.
The flow installation is checked against the manufacturer's installation requirements and the appropriate BS or ISO standards. The flow-meter setup parameters are compared to the original set-up data and changes noted. If such changes affect the overall accuracy of the flow system this is reported back to the Client.
Clients will recieve a written report detailing the findings and making recommendations for improvements. In the event of any serious failures remedial measures will be recommended. Provided the interim survey is satisfactory, a satisfactory verification report will be issued. .
Did you know that when flow-measurements systems give inaccurate readings they nearly always over-read, which costs the Client money?
