When a US energy company needed reliable level measurement of their oil field chemical feed tanks, they turned to Flowline. To improve well production and equipment longevity, anti-scaling chemicals are injected into each well, so as to minimize the salt content of downhole fluids. With hundreds of wells to supply, level measurement is critical, and the operators had problems with pressure sensors due to corrosion, and another brand of ultrasonic sensors due to condensation on the transducer. For this reason, Flowline suggested the use of our non-contact, reflective ultrasonic sensors that work in condensation. The ultrasonic sensors provide continuous level data to the SCADA system, which in turn, monitors the tanks, and alarms for replenishment. Flowline is reliable level measurement.
