Calibration Columns
 |
Calibrate the flow rate of metering pumps. A graduated scale with zero at the top lets you easily see how much fluid is lost over the course of a one-minute test. This will tell you your pump’s flow rate. Periodic testing helps alert you to issues in your system, such as worn or dirty valves. Checking the flow rate after performing maintenance ensures your pump is working properly.
Install the column between your reservoir and pump. They require shutoff access to your reservoir and an on/off valve (not included) at the point where they connect to your system. To start the test, open the on/off valve as the system is running to fill the column with fluid up to the zero mark. Shut off the valve and wait one minute before observing the liquid level in the column. After you've taken the reading, close the on/off valve to the column and reopen access to the reservoir.
Borosilicate Glass Body—Borosilicate glass calibration columns and their fittings stand up to sulfuric acid, hydrochloric acid, and other corrosive chemicals.
PVC Body—PVC calibration columns are a good choice when working with water.
