 First, an overview of open channel flow meter: 

 KLLDM-51 intelligent open channel flow measurement system the method generally consists of a flow indicator, a flow meter, a level gauge component; may also be a flow indicator, flow meter up to four units, a liquid meter consisting of multi-velocity open channel flow measurement system. 
 KLLDM-51 intelligent open channel flow meter system for reservoirs, rivers, water conservancy, urban water supply, wastewater treatment, irrigation, water administration and water resources, rectangular, trapezoidal open channel flow measurement and culverts. 

 Second, open channel flow meter works: 

 KLLDM-51 smart open channel flow meter to flow - water-based algorithm, and using advanced tracking speed of the servo system and the microprocessor level, to ensure speed and accuracy of operation of a new intelligent traffic systems, According to the channel width and the measurement accuracy requirements, the use of front-line point method or multi-line open channel flow measurement method that the mathematical model. 
 Open channel flow system intelligent microprocessor based water level indicator in the actual water level measured value, the output control signals to drive actuators to drive the servo tracking electromagnetic flow meter automatic tracking, the average vertical velocity points in water depths of 0.4 times the flow rate detection, and According to the measured water level, flow rate value and has been placed in the channel geometry, slope coefficient, channel precision, hydraulic ramp, a vertical plane velocity correction factor, according to a predetermined mathematical model to calculate the flow channel. 
 Third, open channel flow meter features: 

 Open channel flow measurement range, the surface flow measurement from tributary backwater effects. 
 Open channel flow measurements of sediment from the water floats, air bubbles and water level changes significantly affect the flow resistance of the sensor on the flow have a simple structure, small size and easy installation. Standard channels does not require the transformation can be directly installed, installation and construction costs low. Functional instrument display output can show the water level, flow, flow, total flow measurements, and has RS-485 communication interface. 
 Open channel flow with water, sludge level, flow rate limit alarm function. 
 Open channel flow meter with data storage capabilities, in the case of long-term power outages and traffic parameter values ??to save the settings.
