When an Ohio system integrator needed reliable level measurement of their customers wastewater and cooling tower sumps, they turned to Flowline. For different reasons, both were problematic. The wastewater was corrosive and foamed up during and after pump transfer, and the tower water was hard, scaling and agitated. In both applications, contact level sensors had limited-service life and were deemed unacceptable. For these reasons, Flowline suggested our non-contact ultrasonic sensors installed in standpipes to dampen the turbulence and isolate foam from the point of measurement. The ultrasonic sensors provide reliable level data to the PLC, which monitors the sumps and controls the pumps and valves. Flowline is reliable level measurement. |
