Open channel flowmeter calibration

The calibration of an open channel flowmeter is determined by the size and shape of the measurement structure. Our Engineers take multiple measurements at critical points throughout the approach channel, gauging structure (flume or weir), and downstream sections. From the measurements, we perform calculations to accurately determine the head to flow relationship of the structure and establish its true zero datum level.

Many of the open channel flow meter calibration calculation formulas are complex, and for high accuracy, need to be performed using dedicated computer software. We have developed our own open channel flow meter calibration software which fully replicates the computations detailed in the current British and ISO standards. Using our calibration software, in conjunction with the experience and specialist tools we have for setting up open channel flow meters, we can ensure that open channel flow meters are functioning to their best possible accuracy.

Following each survey we provide a detailed condition report and a certificate of calibration.
