1、 Overview
LJZ-2 intelligent flow monitor is an intelligent digital instrument that processes standard signals with a single chip microcomputer as the core. It forms a flow monitoring device with a three valve group, a differential pressure transmitter, etc., to form a flow monitoring system for the spiral case of a hydraulic turbine.


2、 Features
■ It is an intelligent digital instrument with a single chip processor as the processing system;
■ The transmitter range and instrument range are easy to set and modify;
■ It has breakpoint memory and parameter automatic protection functions;
■ Instantaneous flow and cumulative flow can be switched;
■ The alarm value can be set freely and adjusted conveniently;
■ Provide standard signal output corresponding to instantaneous flow;
■ Provide transmitter working power supply (+24V);
■ Touch buttons are used, which are beautiful and elegant.
