When an Arizona petrol distributor needed reliable level measurement of their portable diesel storage tanks, they turned to Flowline. The company provides construction, highway, mine and quarry customers with onsite deliveries of fuel, lube and DEF for trucks and heavy equipment. The tanks frequently have no power or connectivity and are normally in place for 1-12 months before being moved to a new site. Without field tank inventory data, customer fuel outages, urgent deliveries or trucks returning with partial loads is inevitable. Frustrated, the operators contracted with a telemetry provider, who selected Flowline ultrasonic level sensors for reliability. Once a day, the solar powered telemetry unit, turns on the ultrasonic sensor, and uploads level data to the operators web page for visibility. Flowline is reliable level measurement.
