1、 System composition of WDK mobile explosion-proof quantitative control system filling cart
1. WDK series explosion-proof flowmeter: This is the foundation of control and directly affects the effectiveness of control. Therefore, the basic requirements are high measurement accuracy, good repeatability and linearity of measurement, and signal output function. At the same time, there are many types of flow meters, and the selection should be based on parameters and requirements such as the measuring medium, the range of material injection, pipeline diameter, flow range, explosion-proof, anti-corrosion, and protection level, in order to choose the appropriate flow meter as much as possible. When selecting, please do not rely on the medium of the material, and refer to requirements such as corrosion resistance, explosion-proof type, feeding amount, and actual control requirements. We will make the specific selection.
2. WDK Explosion proof Quantitative Controller (Box/Cabinet): Contains WDK fully intelligent quantitative controller, internal control circuits and components, external control buttons and indicator lights, etc. The standard size of WDK Explosion proof Quantitative Controller is 220 * 320 * 420mm (height * width * thickness), with optional power supply of DC24V or AC220V. Flow meters or cut-off devices are directly powered by the controller internally. And it can output 4-20Ma, RS485 and other signals for communication to other control devices, and can also add printing function. With the development of requirements for self-control and comprehensive control, corresponding supporting production can also be made according to customer requirements. Comprehensive control and programming control can also be made based on touch screens and PLCs. When more detailed specific requirements are needed, corresponding solutions can be made. At the same time, the price includes the integration of hardware and software programming. Please contact us for specific requirements.
3. Explosion proof control valve equipment: It can be power equipment such as pumps and pressure differentials, as well as explosion-proof valve equipment such as explosion-proof solenoid valves, explosion-proof electric valves, explosion-proof pneumatic valves, etc. In actual operation, we recommend that flow dynamics generated by constant pressure are better because they are stable, safe, and easy to control, such as pressure generated by liquid level height (at least 2 meters or more), or pipeline pressure of tap water itself. In practice, we also need to consider the issue of flow rate. If the actual flow rate cannot be reached, a motor or pump is needed to boost the pressure. At this time, as long as the corresponding power is informed during selection, we will tailor a quantitative control matching solution for you and optimize, select, and provide customers with matching products that meet practical requirements and have high cost-effectiveness.

2、 Control Process of WDK Mobile Explosion proof Quantitative Control System Filling Car
Set the values to be controlled in the WDK explosion-proof quantitative controller as needed. After starting, the WDK explosion-proof quantitative controller outputs a signal to open the pump or control valve. The flowmeter starts measuring and outputs the corresponding instantaneous flow signal to the WDK quantitative controller. The WDK quantitative controller converts and accumulates the instantaneous flow signal based on the flowmeter; When the cumulative value reaches the set control value, the WDK quantitative controller outputs a switch signal to close the pump or control valve, thus completing the function of quantitative control operation.3、 Product Features of WDK Mobile Explosion proof Quantitative Control System Filling Car

6、 Ordering Instructions for WDK Mobile Explosion proof Quantitative Control System Trolley
1. Choose the appropriate flowmeter: inform us of the name of the measuring medium, the diameter of the measuring tube, the working pressure and temperature, the flow range, or other requirements, and we will select the appropriate one for you;
2. Explain the requirements for control, such as explosion-proof requirements, the size of each quantitative value, the frequency of daily control, whether the value controlled each time is the same, and other requirements;
3. Choose a cut-off device: If there is already a cut-off device, please inform us of its working power supply and power, and we will customize it accordingly; If needed, we can also provide a cut-off device. We suggest choosing solenoid valves or pneumatic valves (when delayed start or stop is required) for the cut-off equipment, and not controlling the pump. At the same time, when arranging the pipeline, the stagnant flow generated by the liquid level difference should be used as the power source, which is the most optimal. This will ensure safety and measurement accuracy during control.
