| When a US piping systems manufacturer needed reliable level measurement of their wastewater pH neutralization tanks, they turned to Flowline. The company produces HDPE piping for stormwater applications. The pipes are water cooled as they pass through the extruder, and residual hot wastewater is periodically pumped to mix tanks for neutralization with phosphoric acid. There plant engineers had ongoing problems with a different ultrasonic level sensor brand, due to condensation forming on the transducer, which attenuated the acoustic signal. For this reason, RHFS suggested the use of Flowline’s reflective ultrasonic sensors that are unaffected by condensation. See how. The ultrasonic sensors provide continuous level data to the PLC, which in turn, monitors the tanks and controls the neutralization process. Flowline is reliable level measurement.
