Ultrasonic dual-probe ranging sensor

The ultrasonic dual-probe distance measurement sensor must be perpendicular to the water surface being measured, so that the signal is strongest during measurement. If the offset angle is ＞5°, it may not receive the signal reflected from the water surface. Standard RS485 output (Modbus-RTU protocol), supports 0～10V analog output, convenient for data acquisition and remote monitoring, improving management efficiency. It measures water level through air, so there is no wear on the sensor itself and it is not afraid of adhesion. Reduces maintenance workload and improves safety.
