KENCO Drum Gauges are an important part of a chemical injection skid. Drum Gauges are used to visually monitor the liquid level inventory in horizontal 55 gallon chemical storage tanks. In addition, several models come complete with a test valve to set the injection rate of a chemical metering pump.

The One Minute Test:

To check the pumping rate of a chemical pump, depress the valve handle (or close the ball valve on Model K599).This will isolate the Drum Gauge from the storage tank. Hold the valve closed for one minute and observe the change in level on the scale cast inside the gauge frame. The scale on the left hand side of the gauge glass is calibrated in quarts per 24 hours and the scale on the right is calibrated in liters per 24 hours. The rate observed is 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.
