Product Introduction

Adopting imported incremental photoelectric encoder and combing advanced technologies as speed-changing sheave structure, pulse detection, digital display and microcomputer processing, YX-FWM Float-type Water Level Gauge obtain functions of automatic monitoring and early warning. With its high reliability and strong anti-interference, it can run under the hard environment and has been widely used in the real-time liquid level monitoring of rivers, lakes, reservoirs, petroleum and chemical plant.

Working Principle

The sensor installed on the test tube or above it, when the level changes, the float moves up and down and the testing rope lead line wheel to make an orbiting movement. The encoder connected with the coaxial line wheel output a digital signal corresponding to level and then transmit to main board so that the real-time measurement and display are realized.

Product Features

●Precision winding wheel system and pulse edge sense circuit which are researched and developed independently by Huali, to ensure that no missing pulse, effectively improve the accuracy of measurement;
●Adopting high precision absolute value encoder to ensure that the instrument can accurately measure the liquid level in the power recovery;
