Calibration Columns

A calibration column is a simple yet essential device used to verify and calibrate chemical dosing pumps. It consists of a graduated glass or transparent tube installed in the suction line. Operators fill the column with fluid and measure the volume drawn over a set time. This provides accurate flow rate data. Therefore, it ensures precise chemical injection. Additionally, it helps detect pump wear early. As a result, it prevents overdosing or underdosing. In short, calibration columns deliver reliable performance checks with minimal effort in water treatment, oil & gas, and process plants.
