Description
The One Minute Test
The injection rate is checked by closing a valve between the gauge and chemical storage tank and observing the change in fluid height in one minute. Using the rate scale on the front of the polycarbonate shield, count the number of marks the fluid level passed in the one minute test period. 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. If a higher pump rate is required, the test period can be shortened to 30 seconds or 15 seconds.
