When a Pacific Northwest marine aquarium and mammal rehabilitation center needed reliable level measurement of their saltwater reservoir, they turned to Flowline. Located on the coast, their exhibit and treatment pools are replenished from an underground reservoir that’s frequently refilled with bay water. During which, the high agitation generates surface foam that caused their previous ultrasonic liquid level sensors to go lost due to signal absorption. For this reason, Flowline suggested the use of our pulse radar liquid level sensors that are unaffected by foam or agitation. The pulse radar sensor provides reliable level data to the PLC, which in turn, monitors the reservoir level and controls the transfer pumps. Flowline is reliable level measurement.
