Calibration Capabilities Enable Successful Measurement of Low Conductivity Water

In the spring and early summer, the source water for the newly upgraded Coquitlam Water Treatment Plant in metro Vancouver is mainly snow runoff, which is too low in conductivity for electromagnetic flowmeter (EFM) technology. Ultrasonic flowmeters, thus, became the measurement technology of choice for measuring flow through the ultraviolet (UV) treatment chambers. However, ultrasonic flowmeters needed roughly twice the amount of available upstream straight pipe to achieve the specified accuracies. In a new white paper, KROHNE describes how its ability to calibrate the meters in the designed piping configuration helped the facility overcome this challenge and move forward with ultrasonic metering in the UV process.
