When a California food processor needed reliable level measurement of their wastewater storage tank, they turned to Flowline. The firm cleans roasts, packages and ships coffee beans and grinds to private label customers. A two-day wash and soak process separates the beans outer sticky pulp layer from the inner coffee seed. The resulting waste stream is pumped to a street side storage tank awaiting tanker truck haul away to an offsite treatment facility. There the operators complained that previous pressure level sensors frequently clogged and required ongoing maintenance. For this reason, Flowline suggested our non-contact ultrasonic sensors that are ideal for viscous, coating and scaling wastewater. The ultrasonic sensor provides reliable level data to the PLC, which transfers the waste and alarms for tanker truck pick up. Flowline is reliable level measurement.
