Ensuring Accuracy And Precision In Chemical Metering Systems


In water treatment, chemical metering is a key aspect of a wide range of processes, including disinfection and pH balancing. Accuracy and precision are critical for effective chemical treatment, where even slight variations may have significant consequences.

Over- or under-dosing chemicals can result in failing to meet treatment outcomes, regulatory non-compliance, damage to infrastructure, and more. Thankfully, most metering pumps and related equipment are easy to use, provided a few simple steps are taken during initial installation and throughout their usage lifetime. This includes calibration, regular inspection, and maintenance, ensuring material compatibility with the chemicals being dosed, and proper instrument selection.

By following the guidelines below, operators can ensure the reliability and consistency of their chemical dosing systems.
