Products Description
Model AFLSS-23 Continuous Level Sensor with wireless Transmitter/Receiver set operates with a vertical mounted, stainless steel float sensor that is ideal for monitoring liquid height in many applications. The sensor and 2.4GHz wireless transmitter combination accomplishes remote tank level measurement by sending a wireless current or voltage output signal up to 6 miles away that corresponds to the position of the float as it travels up and down the sensor's shaft. You can connect the wireless receiver output to a process meter or PLC to control a pump, valve or alarm unit. These level sensors are rugged, reliable and available in a wide variety of lengths to 42".
