When an Ohio metal finishing firm needed reliable level measurement of their wastewater tanks, they turned to Flowline. The company etches, anodizes, plates and polishes parts for aerospace, military and marine customers. Their liquids range from solvents to acids and their wastewater streams are corrosive, dirty, foaming and potentially explosive. The operator required a non-contact level sensor that would operate reliably under these conditions with a level indicator and repeater for the PLC. For these reasons, Flowline suggested our intrinsically safe ultrasonic sensor installed in a standpipe and connected through an IS barrier to our indicator with repeater and windowed NEMA enclosure. The ultrasonic sensor provides reliable level data to the indicator which displays level height in feet, and repeats the signal to the PLC. Flowline is reliable level measurement. |
