When an Arizona county fire authority needed reliable level measurement of their remote diesel tank refueling stations, they turned to Flowline. As heavy equipment fire trucks and bull dozers are deployed deeper off grid, they must be refueled using helicopters. To do so, the county maintains remote fuel stations with helicopter landing pads and lift hoist bladder tanks through which they can fill, transport and deliver diesel from the air. There the county wanted a reliable, intrinsically safe, non-contact level sensor that would interface with their SCADA for remote inventory monitoring. For this reason, Flowline suggested our ultrasonic level sensors that are ideal for diesel fuel. The ultrasonic sensors provide reliable level data to the SCADA which alarms for refill. Flowline is reliable level measurement.
