## Description

The liquid level sensor measures the height of the liquid and converting it to the Modbus-RTU protocol. It works with a data logger or other devices that support the RS485 Modbus-RTU protocol. The liquid level sensor has a built-in high-performance and highly sensitive silicon piezoresistive core. The internal chip converts the sensor's millivolt signal into a standard protocol which can be connected to a computer, control instrument, or PLC.

It's small-size, lightweight, and easy to install. It has a stainless steel sealing structure that can work in a corrosive environment. The sensor has high anti-vibration and anti-impact performance. It can be widely used in process control, aviation, aerospace, automobile, medical equipment, HVAC, and other applications.
