Flow quantitative control system

Summary:

Quantitative control system is the use of flowmeter, cut-off device, and a kind of quantitative controller can realize liquids such as oil, grease and chemical products can be realized automatic quantitative filling ratio or quantitative measurement, tank level measurement device, and can realize production area and management office computer network at the same time, has extensive practicability.

System features:

1、Only need the composition of flow meter, quantitative control instrument and cut-off equipment, simple structure, low cost, and system control accuracy ±0.2%；

2、custom-made control box, quantitative control device, simple wiring, generally no adjustment to the site, Flowmeter and cut-off equipment have power supply in the control box, only need to provide AC220V to the control box;

3、The control box panel is provided with "start", "stop" and "reset" button, and the "status indicator light" is displayed, which can be performed on site. Therefore, the display is intuitive, easy to operate, convenient and easy to learn；

4、The quantitative control instrument can choose the digital tube display and Chinese liquid crystal display type to meet the on-site demand.

System composition:

1、Flow meter:

According to the parameters of measuring medium, pipe diameter, flow range, explosion-proof, anti-corrosion, protection grade and other parameters and field requirements, the proper flowmeter is selected. The accuracy of the flowmeter is very important, which determines the overall control accuracy.

2、Quantitative control instrument:

Quantitative control instrument is a kind of electromagnetic、orifice、vortex street、 turbine flow sensor glug signal through signal processing, such as operation, display and output contact fluid with electromagnetic valve combination of batch control instrument, through batch fill values and schedule, work mode with size valve or achieve precise quantitative control, simple pendulum, pump valve linkage, and hand/since the model flexible configuration, convenient for users to realize single filling and batch control, instrument injustice with prescribing, tired, rich functions such as alarm, also can realize the keys remove alarm, sensor disconnection alarm and other special function, and can output 4-20 ma,RS485 communications fully meet the needs of different users in different occasions.

3、Interrupting device:

Can be pump and other power equipment, or can be such as solenoid valve, electric valve, pneumatic valve and other equipment.
