When a Mississippi automobile rental company needed reliable level measurement of their wash wastewater recovery tank, they turned to Flowline. The wash containment bay drains to a sump which pumps its contents through a filter to a holding tank that’s prior to batch treatment and recirculation to the wash bay. There the operator complained that previous pressure level sensors clogged, and float level sensors stuck, and they needed maintenance free level measurement. For this reason, Flowline suggested our non-contact ultrasonic sensors that are ideal for wastewater applications. The ultrasonic sensor provides reliable level data to the PLC which controls the sump and treatment process. Flowline is reliable level measurement.
