When an Illinois groundwater remediation firm needed reliable level measurement of their bulk tanks, they turned to Flowline. Their customer, a commercial real estate developer purchased land that’s adjacent to a former heavy equipment yard with diesel fuel contamination. Shallow wells were dug, and the contractor pumped the top oily layer of groundwater into two manifolded storage tanks for offsite treatment and disposal via tanker trucks. There the operator needed a reliable, non-contact level sensor that would measure the tanks fill and actuate a high-level alarm for his crew to shut off the pump. For these reasons, Flowline suggested our ultrasonic sensors with embedded relays and configurable logic via WebCal software. The ultrasonic sensor provides reliable level measurement and alarm actuation. Flowline is reliable level measurement.
