When a Southern California aerospace company needed reliable level measurement of their wastewater bulk storage tanks, they turned to Flowline. As the wastewater is pumped to the treatment system, the agitation generates foam, and the operators had experienced problems with their ultrasonic sensors due to acoustic signal absorption. For this reason, Flowline suggested the use of our pulse radar liquid level sensors that are unaffected by surface foam. The pulse radar sensor provides reliable level data to the PLC, which in turn, monitors the bulk storage tanks, and transfers the wastewater into treatment. Flowline is reliable level measurement.
