Greywater Storage Tank Ultrasonic Level Measurement

When a California sports park needed reliable level measurement of their greywater storage tank, they turned to Flowline. On busy weekends, the park supports hundreds of guests with one concession kitchen, four bathrooms and two outdoor showers. To conserve water, the sinks and showers drain to a reclamation system that collects, filters, treats and transfers the water to a hillside storage tank, that gravity feeds back to flush twenty-four toilets. The park supervisor complained that the past ultrasonic level sensor became erratic during the twice daily condensation cycles in the tank, which resulted in false alarms and system shutdowns. For this reason, Flowline suggested our proprietary reflective ultrasonic sensor that’s unaffected by condensation. The ultrasonic sensor provides reliable level data to the PLC, which monitors the storage tank and controls the transfer pump. Flowline is reliable level measurement.
