The stay rod type pump setting gauges are used to calibrate the flow rate of chemical metering pumps and chemical injection systems. They are also used to periodically monitor the performance and accuracy of a chemical injection system. It can also be used as the primary containment reservoir of a fluid that will be pumped into a chemical injection system.
To check the pumping rate of a chemical pump, isolate the chemical in the tank from the pump setting gauge. One of the stay rods supporting the gauge glass is calibrated in division marks that represent either gallons per hour, gallons per day, liters per hour, liters per day, gallons, or liters. Keep the isolating valve closed and observe the number of marks the fluid level passes in one minute. This will give you the actual chemical pump rate. If the rate is not the one desired, make an adjustment to the chemical pump feed rate and conduct as many one minute tests as is necessary to set the chemical pump rate to the rate desired.
