ND101 Submersible Level Transmitter

Product Description

The ND-101 liquid level transmitter utilizes high-stability, high-reliability imported sensor chips and high-precision intelligent transmitter processing circuits. It adopts precision digital circuit technology and nonlinear correction technology, making it a high-precision liquid level measurement product. The waterproof and gas-conducting electric fence is connected to the surgical seal, with the vent tube inside the electric fence, allowing it to be used in liquid for long periods. The integrated structure and standardized output signal provide convenience for on-site use and automatic control. The product operates in a two-wire system, featuring a compact size, light weight, easy installation, and convenient use. It is suitable for liquid level measurement and control in the fields of petroleum, chemical industry, power plant, urban water supply, and hydrological exploration.
