When a US piping systems manufacturer needed reliable level measurement of their wastewater pH neutralization tanks, they turned to Flowline. The company produces HDPE products for stormwater applications. Pipes are water cooled as they pass extrusion, and the residual hot wastewater collects in mix tanks for neutralization with phosphoric acid. There the operators had problems with a different ultrasonic level sensor brand due to condensation, and the resulting acoustic signal attenuation. For this reason, Flowline suggested the use of our reflective ultrasonic sensors that are unaffected by condensation. The ultrasonic sensor provides continuous level data to the PLC, which in turn, monitors the tanks, and controls the neutralization. Flowline is reliable level measurement.
