Mottech Submersible Water Level Sensor
Overview
Mottech Submersible Water Level Sensor is with stainless steel isolation diaphragm diffusion silicon pressure core body,
the pressure core body adopts the process of laser trimming resistor for a wide temperature range of zero and sensitivity temperature compensation.
Special cable for air-venting conduit and waterproof technology ensures water tightness, and ventilation between inside and outside, so as to acquire accurate and stable measuring data.
The Mottech Submersible Water Level Sensor can be connected directly to any controller in Mottech’s system via Analog input or Mottech Smart Card.

Dimensions
Unit: mm
The default diameter is 27 mm.
19 mm or 13 mm external diameter is customizable.
Mounting
- As shown in picture 1, when the sensor is installed in static water such as in pools, water towers, probe is immersed into the bottom and should be as far as possible away from the pump or valves.
The terminal box should keep above water surface and prevent water penetrating into cables.
Please make sure the airway not be blocked. - As shown in picture 2, when the sensor is installed in dynamic water such as dams or rivers, probe should be inserted into a steel pipe (inner diameter is around 45mm), burrowing several holes at different height on the pipe side wall which is opposite to the water flow direction. The terminal box should keep above water surface and prevent water penetrating into cables. Please make sure the airway not be blocked.
