Worthington Enterprises SureSense propane level sensing technology is designed to increase the reliability of tank level readings. SureSense is first available in Worthington 420 pounds heating and system reservoirs. The technology eliminates moving parts inside the tank and provides a more reliable reading of the propane level remaining in the tank. Using a low-energy Bluetooth signal, SureSense provides accurate readings directly to a monitor without using cables that are easily damaged in the field, according to the company. SureSense also helps propane marketers eliminate the results of inaccurate readings: costly customer leaks and operational inefficiencies, Worthington adds.
