When a North American metal finishing equipment manufacturer needed reliable level measurement of their plating baths, they turned to Flowline. This system has four vessels including the primary, two for plating and one for pump recirculation that each require level control. Tired of ongoing conductance level switch failures, the engineering team wanted non-contact measurement, but found that typical ultrasonic level sensors were equally unreliable due to the acoustic signal attenuating effects of condensation and foam. For this reason, Flowline suggested the use of our proprietary reflective ultrasonic level sensors that are unaffected by condensation, installed in a stand-pipe. The ultrasonic sensors provide continuous level data to the PLC, which in turn, monitors the baths and controls the process. Flowline is reliable level measurement. |
