When a Midwest manufacturer of metal shopping carts needed reliable level measurement of their wastewater holding tanks, they turned to Flowline. Hot and ambient waste streams are reclaimed into outdoor tanks awaiting treatment and reuse. There the operators noticed that when hot waste entered the tanks on cold days, their previous ultrasonic level sensors would become unstable. Further inspection revealed that the condensing liquid vapor was forming acoustic signal attenuating water droplets on the sensor transducers. For this reason, Flowline suggested the use of our award winning reflective ultrasonic level sensors that are unaffected by condensation. The ultrasonic sensors provide continuous level data to the PLC which pumps the waste streams and manages the treatment process. Flowline is reliable level measurement.
