<:
The series flow quantitative control system cooperates with various flow sensors and transmitters to realize quantitative filling and batching control. The main technical features are suitable for flow sensors with current pulse output
<:
point switch input, used for starting, recovery, and clearing the accumulated value to zero each time
<:
point Control output, used for hierarchical control of large and small valves and instantaneous flow lower limit alarm transmission output, which can output the instantaneous flow value in the form of standard current and voltage for use by other equipment.
: The flow quantitative control system mainly feeds back the pulse flow signal to the quantitative controller based on the flow meter. When the cumulative flow rate reaches the set value
: Quantitative value
)
:, The quantitative controller will give a switch signal to the solenoid valve or pump to control the start and shut down of the valve pump. Realize automatic and manual control of feeding.

: Currently, it is one of the items that many companies use or need to improve, especially some that still use manual canning operations
/
: cutting materials, and also Enterprises that want to improve work efficiency without investing too much cost are recommended to adopt this system. The system has high accuracy, is easy to operate and can be calibrated on site.
: Composition of a system

Flowmeter: This is the basis of control and directly affects the effect of control. Therefore, the basic requirement is that the higher the measurement accuracy, the better, and it has a signal output function. At the same time, there are many types of flow meters, and it is necessary to select the appropriate flow meter based on parameters such as the diameter and flow range of the measurement medium pipe.

Temperature sensor: can measure the temperature of the medium on site, and the quantitative controller automatically compensates for errors caused by temperature changes
: optional
)

Quantitative controller: quantitative control parameter setting, medium flow display, cumulative operation, etc.

Control box: internal control circuits and components, external control buttons and indicator lights, etc.
: Optional
)

Cut-off equipment: It can be the existing power equipment in the pipeline, such as a pump or a solenoid valve installed afterward.
: Second control process

: After receiving the flow signal from the flow meter, the quantitative controller completes the accumulation of flow internally, and at the same time sets the required quantitative value inside the controller. Control value, when the accumulated value displayed by the quantitative controller reaches the set quantitative control value, the quantitative controller outputs a switching signal. At this time, the switch signal is used to control the interrupting device installed on the pipeline by connecting a relay or contactor, thereby achieving quantitative control effects.
: Three product features

: The control circuits and components in the control box are customized according to the flow meters and equipment required by the customer. The signal line is simple to connect and is generally not required after arriving at the site. Adjustment

: The control box panel is equipped with

: Start
:

: Stop
: etc. buttons, and there are

: Status indicator light
: Display, so the display is intuitive, the operation is simple, convenient and easy to learn

: Each quantitative control value can be changed as needed, just The operation in the quantitative controller is completed

: The displayed parameters of the quantitative controller include the total cumulative instantaneous flow rate, time, flow meter input signal value, etc.

: Equipped with large and small valve controls, Control large flow and small flow respectively to achieve precise quantitative control

: Equipped with a material query function, which can query the total material times, each material time, each material quantity, etc.
