Full channel wide electromagnetic open channel flowmeter

L D M-5 1 intelligent open channel flow measuring system (full channel wide box type electromagnetic open channel flow meter) is the only intelligent measuring device that can directly measure the average flow speed of the overflow section. The whole channel wide box electromagnetic open channel flow meter adopts the flow speed-area method, consisting of the whole channel wide electromagnetic flow speed sensor, liquid level sensor and intelligent converter. The working principle is to calculate the section area measured by the area of the channel. The water level of the level meter with different principles, the liquid level meter is generally measured by ultrasonic level meter, pressure level meter, etc. The measurement system can realize precise flow control function by combining gate, solar control system and wireless communication remote control, which is the basis of gate linkage control and information solution in irrigation area.

Product Introduction

　　Functional features

　　The measurement system can measure the real-time water level, the average flow rate, and the cumulative flow rate;

　　Reasonable mathematical model and advanced technology technology multi-electrode automatic tracking measurement can accurately measure the average section flow velocity of different forms; the measurement range is wide (0.01-10m/s);

　　Two-way flow measurement;

　　Measurement is not affected by floating objects, sediment content, water level changes, sedimentation and temperature;

　　The flow speed sensor is convenient to install and has no resistance to the water flow. Standard section does not need to be directly installed, installation construction difficulty is small, low cost;

　　Instrument display function: can simultaneously display water level, section average flow speed, section instantaneous flow, accumulated flow, etc.

　　Supporting gate can achieve accurate measurement and control integration, measure before and rear gate water level and gate opening, etc.; with permanent data storage function, and set parameters and flow value can be saved in the case of long-term power outage;

　　The instrument has standard 485 interface with ModBus (RTU) output and dual analog input interface. Technical parameters
