The quantitative water supply system is composed of an intelligent quantitative totalizer and a flow sensor. The flowmeter feeds back the pulse or current signal of the quantitative controller. When the cumulative flow reaches the set value (quantitative value), the quantitative controller will give the solenoid valve A switch signal of the water pump can control the valve or the water pump. Realize automatic and manual control of feeding. The system has high accuracy, simple operation, and can be calibrated on site. The system is simple to use and maintain, and is widely used in chemical, food, and feed industries for quantitative water addition.
电磁阀＋定量控制箱 1. System composition: flow sensor (flow meter) + pump + solenoid valve + quantitative control box
、流量计直接影响控制的效果，因此基本要求是测量精度越高越好，有信号输出功能；同时流量计种类较多，要选择合适的流量计。 1. The flowmeter directly affects the control effect, so the basic requirement is that the higher the measurement accuracy, the better, and the signal output function. At the same time, there are many types of flowmeters, so you must choose a suitable flowmeter.
、定量控制箱，控制箱内部器件根据客户需要定制安装。 2. Quantitative control box, the internal components of the control box are customized and installed according to customer needs.
、断流设备：可以单独或同时控制管线的泵和电磁阀、电动阀，输出有多路时可以进行多路转换；加电磁阀是因为起到即停即开的作用，有利于控制精度的提高。 3. Flow-cutting equipment: The pumps, solenoid valves, and electric valves of the pipeline can be controlled individually or simultaneously. Multiple outputs can be switched when there are multiple outputs; the addition of the solenoid valve is to stop and open, which is good for control accuracy. Of improvement.
、流量传感器：流量传感器主要是采集流量信号，反馈给定量控制仪。 1. Flow sensor: The flow sensor mainly collects the flow signal and feeds it back to the quantitative controller.
、定量控制箱：主要有定量控制仪表＋电箱组成。 2. Quantitative control box: It mainly consists of quantitative control instrument + electric box.
Function description of electric control box:
、定量控制仪：可任意设置所需要加入的水量（定量值） 1. Quantitative controller: the amount of water (quantitative value) to be added can be arbitrarily set
After receiving the signal from the measurement sensor, the quantitative controller completes the accumulation and display in the internal, and at the same time sets the
Set the required quantitative control value. When the cumulative value displayed by the quantitative controller reaches the set quantitative control value, the quantitative
The controller outputs switching signals. At this time, the switch signal is used to control the installation on the pipeline through a matching relay or contactor.
The cut-off equipment such as valves, etc., to achieve the effect of quantitative control. With instantaneous flow, cumulative flow, added quantity display
、恢复按键：既在突然断电或其他原因造成定量控制中途停止时，按恢复键可以继续加入 2. Resume button: When the quantitative control stops in the middle of sudden power failure or other reasons, press the resume button to continue adding
Unfinished quantitative value.
、停止按键：遇到紧急情况，可按此键停止阀门 3. Stop button: In case of emergency, you can press this button to stop the valve
、启动按键：每次操作完成后，按此键可以将定量值清零，重新开始下一批次操作。 4. Start button: After each operation is completed, press this button to clear the quantitative value and restart the next batch of operations.
Product features of quantitative water supply system
、只需要计量传感器、控制箱和断流设备组成，结构简单，成本低； 1. It only needs to be composed of measurement sensor, control box and cut-off equipment, with simple structure and low cost;
、控制箱内的控制线路及组件是根据客户所需要的计量传感器和设备量身定制的，信号线 2. The control lines and components in the control box are tailored according to the measurement sensors and equipment required by the customer, and the signal lines
Simple connection, generally only need to connect the sensor line and the control box line, and generally do not need to adjust after the scene, the flow meter and
即可； Power interruption equipment and other devices have power in the control box, only need to provide AC220V to the control box;
、控制箱面板设有“启动” 、 “停止”和“清零”等按纽，并有“状态指示灯”显示，因此 3. The control box panel is equipped with buttons such as " Start " , " Stop " and " Clear " , and has a " Status Indicator " display, so
Intuitive display, simple, convenient and easy to learn;
、定量控制仪为LED高亮数码管显示，适合较远的距离观察，液晶显示就无法远距离观察 4. Quantitative controller is LED high-brightness digital tube display, suitable for long-distance observation, the liquid crystal display cannot be observed from a long distance.
V. Precautions for purchasing quantitative watering system
、选择合适的流量计，流量计相关参数（测量介质、管道口径、工作压力和温度、流量范 1. Select a suitable flow meter and related parameters of the flow meter (measurement medium, pipe diameter, working pressure and temperature, flow range
、说明控制的要求，例如每次定量值的大小、控制的频率、以及其他要求等； 2. Explain the control requirements, such as the size of each quantitative value, the frequency of control, and other requirements;
、选择断流设备：如已有断流设备请告之其工作电源和功率，我们作量身订制；如需要我 3. Choosing a current-cutting device: If there is already a current-cutting device, please inform it of its working power source and power, and we will customize it; if necessary, I will
It is also possible for us to provide a cut-off device; we recommend that the cut-off device be a solenoid valve or an electric valve.
