The KENCO Accu-Rate Pump Setting Gauges® utilize precision scientific glass to provide the most accurate reading possible for calibrating the flow rate of a chemical metering pump. They are also used to periodically monitor the performance and accuracy of a chemical injection system. Additionally, the Accu-Rate Pump Setting Gauge® can be used as the primary containment reservoir of a fluid that will be pumped into a chemical injection system.

The One Minute Test

To check the flow rate of a chemical pump, isolate the chemical in the storage tank from the Accu-Rate Pump Setting Gauge®. The decal on the gauge glass has (2) individual rate scales. The scale on the left side is a volume scale in milliliters. In a one-minute test, the scale will read the pump rate in milliliters per minute. The scale on the right will depend on what type type of flow rate is required; i.e. U.S. Gallons by Volume, Gallons per Hour, Gallons per Day, Liters per Day or Liters per Hour. Keep the isolating valve closed and observe the number of marks the liquid level passes in one minute. This will give you the actual chemical pump flow rate. If the rate is not the one desired, make an adjustment to the chemical pump flow rate and conduct as many one-minute tests as is necessary to set the chemical pump rate to the rate desired
