Pump Flow Calibration

In Florida, it is a state requirement that all commercial pumps and meters are checked and calibrated every 3 years. Today, we called upon Certified Meter Accuracy Tester, Delynn Salafrio. Delynn is the owner and operator of Agricultural Permitting Services L.L.C. She has over 20 years experience in the agricultural industry.

Both courses have pumps houses with (3) 50Hp VFD pumps and a Flowtronex control panel. The accuracy of the Flowtronex flow meter was checked using a state certified Panametric meter. The Panametric meter uses ultrasonic technology to give an accurate flow/GPM reading from inside the pipe. This Panametric reading can sometimes be different than the output the Flowtronex computer is logging. If a difference between the readings is found, the Flowtronex computer must be adjusted accordingly. The state allows for a 5% window of inaccuracy and with some minor adjustments both pump houses will meet state requirements for another 3 years.

Here is a picture of the Panametric Ultra Sonic Meter.
