When a Missouri truck stop needed reliable level measurement of their DEF bulk storage tank, they turned to Flowline. The full-service station provides everything the trucking community needs including diesel exhaust fluid at the pump. A corrosive mix of urea and water, DEF is harsh to many metals and elastomeric seals. The operator said that the past pressure level sensor was replaced twice in a year due to leakage. They wanted a reliable, corrosion resistance level sensor that can be safely installed in a hazardous area. For these reasons, Flowline suggested our non-contact and intrinsically safe ultrasonic sensor. The ultrasonic sensor provides reliable level data to the operators in-store display, which indicates the DEF level. Flowline is reliable level measurement.
