Product description
The full channel width measurement and control integrated measurement system uses the flow-area method measurement principle as the basic measurement method. It is composed of a full channel width electromagnetic flow sensor, a liquid level sensor and an intelligent converter. Its working principle is to measure the full channel width electromagnetic flow sensor. The obtained average flow velocity of the section is combined with the real-time water level measured by the liquid level gauge to calculate the section area. The average flow velocity of the section is multiplied by the section area to obtain the channel flow. Liquid level gauges of different principles and forms can be used to measure the water level of the section. The liquid level gauges are generally ultrasonic level gauges, pressure level gauges, etc.
The measurement system can be combined with gates, solar control systems, wireless communication remote control, etc. to achieve precise flow control functions. It is the basis of gate linkage control and irrigation area information solutions.
Features
- 01The measurement system can measure real-time water level, average flow rate and cumulative flow;
- 02Reasonable mathematical model plus advanced process technology, multiple pairs of electrodes for automatic tracking measurement, can accurately measure the average flow velocity of different forms of section;
- 03Wide measuring range (0.01-10m/s);
- 04Two-way flow measurement;
- 05The measurement is not affected by floating objects in the water, sediment content, water level changes, and temperature;
- 06The flow rate sensor is easy to install and does not produce resistance to water flow. The standard section can be installed directly without modification, and the installation and construction are difficult and low cost;
- 07Meter display function: it can display water level, average flow velocity of section, instant flow of section, cumulative flow, etc. at the same time;
- 08The use of supporting gates can realize accurate measurement and control integration, and can measure the water level before and after the gate, and the opening degree of the gate;
- 09It has the function of permanent data storage, which can save the set parameters and flow value in the case of long-term power failure;
- 10The instrument has a standard modbus (RTU) output 485 interface and dual analog input interface for supporting use.

Notes for use 1. The installation location should be chosen as far as possible in a relatively straight section of the channel or river, and the instrument specification should be close to the channel width. 2. All connecting wires of the intelligent open channel flow measurement system should be as short as possible, avoid power cables as much as possible, and make the connection wires waterproof, moisture-proof, break-proof, and shielded to ensure that the wiring is correct. 3. Cooperate with gate control installation to choose flow meter with matching caliber.
