product details

1、 The composition of the quantitative control system for oxygen:
1. Flow meter/liquid level gauge/weighing sensor: This is the basis of control and directly affects the effectiveness of control. Therefore, the basic requirement is that the higher the measurement accuracy, the better, and it has signal output function. At the same time, there are many types of flow meters, and the selection of suitable flow rates should be based on parameters and requirements such as measuring medium, pipeline diameter, flow range, anti-corrosion, explosion-proof, and protection level: (turbine flow meter, elliptical gear flow meter, electromagnetic flow meter, mass flow meter, V-cone flow meter, rotor flow meter, vortex street flow meter, ultrasonic flow meter, waist wheel flow meter, orifice flow meter, etc.).
2. Quantitative control system: It includes an intelligent quantitative control instrument, internal control circuits and components, external control buttons and indicator lights, etc. The standard size of the box is 400 * 300 * 200mm (height * width * thickness), and the explosion-proof standard size is 460 * 360 * 250mm (height * width * thickness). The power supply is DC12V, DC24V, DC110V, AC220V or AC380V, and the flow meter or level gauge, valve, and pump are directly powered by the controller. And it can output signals such as 0-10mA, 4-20mA, RS485 to other monitoring and control devices, and can also add printing function.
3. Cut off equipment: Select the appropriate valve (such as solenoid valve, pneumatic ball valve, electric valve, etc.) based on the diameter, medium, pressure, and temperature. The power source can be self flowing generated by the liquid level difference, and the pump (voltage and power of the pump need to be provided). We tailor and provide supporting equipment.

2、 Product features of oxygen quantitative control system:
1. It only requires a flow meter/level gauge/weighing sensor, controller, and cutoff device, with a simple structure and low cost;
2. The control circuit and components inside the controller are customized according to the flow meters and equipment required by the customer. The signal line connection is simple and generally does not need to be adjusted after arriving at the site. The flow meters and cutoff devices are powered by the controller, and only AC220V/AC380V needs to be provided to the controller;
3. The controller panel is equipped with "start", "stop", and "reset" buttons, as well as a "status indicator light" display, making the display intuitive, the operation simple, convenient, and easy to learn;
4. The quantitative controller is equipped with a fully Chinese/English LCD display, and the quantitative control value can be changed as needed each time. It only needs to be operated within the quantitative controller;

5. Customizable and customizable automatic control function for cyclic batch, such as setting the number of material releases and the start time for intermediate intervals; By default, 8 advance quantities can be set (only a few can be used), and the material will be automatically issued in sequence. The interval time in between can be set, and the work will automatically stop after one cycle;

6. Customization of functions such as mixing before material distribution or mixing after material distribution, alarm, etc;

7. Multi configured output signal function: USB material recording data export function, instantaneous current output, current output of current accumulation and pre shipment quantity, RS485 \ RS232 communication;

8. Customizable infrared, external button control, remote control

9. Multi way solenoid valve switching controls which tank to feed into, and multi way pump switching controls the feeding of backup pumps or other storage tanks;

3、 Installation precautions and schematic diagram:

1. The installation of the flowmeter should refer to the installation and use manual of the purchased flowmeter

2. The installation of valves should be located as close as possible to the outlet position to ensure the accuracy of material distribution

3. Try to avoid installing the pump near the flow meter as much as possible to prevent interference
