Product Overview

    HW-1088 leak positioning monitoring module can be monitoring the BTR for 1500 meters Leach sensing line，once detect liquid, It will positioning leak position which displayed by LED and produce the sound-sight alarm. Also the position will be sent to the monitoring system by RS485 interface. HW-1088 adopts MODBUS RTU MODBUS RTU protocol to communicate with the monitoring system, so users can integrate the HW-1088 into different system conveniently.
