When a Northeast helicopter manufacturer needed reliable level measurement of their acid day tanks, they turned to Flowline. The firm machines, cleans and finishes metal parts to exacting specifications with acids and solvent. The process is supplied by eight, centrally located day tanks that automatically refill from chemical bulk storage. The maintenance team was dissatisfied with previous Teflon level switches that would inevitably corrode in the acids, and force process downtime. They wanted reliable level measurement and intrinsic safety due to the acid tanks proximity to the flammable solvent. For these reasons, Flowline suggested our intrinsically safe, non-contact ultrasonic sensors, connected through Zener barriers in the panel. The ultrasonic sensors provide reliable level data to the PLC, which monitors and refills the acid day tanks. Flowline is reliable level measurement.
