When a California grower needed reliable level measurement of their fertigation chemical feed tanks, they turned to Flowline. The company grows and sells grapes to large wineries, and this season they replanted 3,000 acres with new seedlings. To establish and sustain rigorous growth, the farmer injects combinations of nitrogen based fertilizers into their irrigation pumping stations. The farmer complained that previous pressure level sensors were not chemically compatible with all fertilizers, and they were done with failures. For this reason, Flowline suggested our reliable, non-contact and corrosion resistant ultrasonic sensors. The ultrasonic sensors provide reliable level data to the telemetry unit, which alarms for chemical truck replenishment. Flowline is reliable level measurement.
