Discuss the effect of quantitative pneumatic valve used in water equipment

quantitative pneumatic valve control system and all kinds of flow sensor, transmitter, quantitative filling and batching control. Then quantitative pneumatic valve in water equipment has what effect? We can look at the following introduction.
the main technical characteristics is suitable for the flow of electric current, pulse output sensor point switch input, used to launch and recovery, and each time the cumulative value of zero point control output, to control the large pneumatic valve, pneumatic valve and instantaneous flow rate lower limit alarm analog output instantaneous flow rate value can be output in the form of standard current, voltage, for the use of other equipment. Quantitative control water equipment

quantitative pneumatic valve control system is mainly based on quantitative control instrument meter feedback to signal pulse flow, when the flow accumulative flow to achieve the set value ( Quantitative values, the controller will give electromagnetic pneumatic valve or pump a switch signal, has reached the startup and shutdown control of pneumatic valves, pumps. Realize the automatic and manual control of the feed.
at present many enterprises can use one of or is in need of improvement projects, in particular, some still use manual operation canned/play, also don't want to put too much cost at the same time, want to improve the efficiency of enterprise was recommended in this system. The system of high precision, simple operation, can be field calibration. A

quantitative control, system composition and water equipment, flow meter, which is the basis of the control, directly affect the control effect, so accuracy of measurement are basic requirements, the higher the better, a signal output function. Flowmeter sort is more, also according to the measured medium, selection of parameters such as pipe diameter, flow range, choose the appropriate flow meter.
, temperature sensors, field measurement medium temperature, by quantitative control instrument according to the error due to temperature change and automatic compensation ( Optional
and quantitative control instrument: quantitative control parameters setting, medium flow display, integrating, running etc.
, control box: internal control circuits and components, external control button and the indicator light, etc. ( Optional
, cut-off device: can be a pipe of the existing power equipment, such as the pump; Also can be installed after the solenoid pneumatic valve etc.

2, the control process of quantitative traffic signal controller at the receiving of the flowmeter, completed in the internal flow of the total, at the same time inside the control instrument needed to set quantitative control values, when the quantitative control instrument display of the total value to set quantitative components, quantitative control instrument switch output signal. The use of the switch signal relay or contactor to control through cut-off equipment installed on the pipeline, so as to achieve the effect of quantitative control.
3, the characteristics of quantitative control
water equipment, control box, control circuit and components of the flowmeter is based on customer need and customized equipment, signal wire connection is simple, general need to adjust to the scene;
, control box panel is equipped with the 'start' and 'stop' button, and a 'light' show, so direct display, operation is simple, convenient, easy to learn;
quantitative control values, each time can according to need any changes, just within the quantitative control instrument operation is completed;
and quantitative control instrument display parameters include the cumulative, total cumulative values of the input signal, instantaneous flow, time, flowmeter, etc. ;
and is equipped with pneumatic valve size control, control flow and small flow, respectively, to achieve accurate quantitative control;
, has hit the query function, can inquire the total playing time, every time, every time playing shoes, etc
