When an Ohio truck and heavy equipment rental company needed reliable level measurement of their wash system tanks, they turned to Flowline. The firm rents dozers, excavators, loaders and backhoes to construction, oil & gas and mining contractors across the state. Upon return, the equipment is washed, inspected and serviced. Cleaning starts with a two man power wash and each washer is supplied by a recirculating warm water storage tank. There the staff had reliability problems with a different ultrasonic level sensor brand that often became intermittent, due to the attenuating effects of condensation on acoustic signals. For this reason, Flowline suggested the use of our reflective ultrasonic sensors that are unaffected by condensation. The ultrasonic sensors provide reliable level data to the PLC, which monitors the tanks, and controls the tank refill process. Flowline is reliable level measurement.
