Page 3: About This Document
PVDF material and designed to withstand IP68 conditions, the RLI-80 withstands the harshest conditions. The 1.5” NPT or G1.5 mounting provides adaptability to be used in tanks as large as 49.2 ft (15 m). The RLI-80 is unaffected by changes in physical properties of the application such as pressure, temperature, or vapors. -

To find the liquid level, the sensor subtracts the height of the air (non-liquid space) from the total depth of the tank. This subtraction yields the precise liquid level 3.5 Sensor Configuration RLI-80 comes standard with integrated Bluetooth® connectivity that allows for the application parameters (Sensor Height, Fill Height) to be adjusted via standard smartphone/tablets. 4.
