Liquid level high and low control equipment

Overview of Liquid Level Control Equipment:

Liquid level height control equipmentProduct features: Control of liquid level quantitative control device (liquid level control device): The liquid level control instrument in the quantitative control box (control box) can manually set the liquid level value (note: the set liquid level value must be within the total range). When the liquid level value reaches the set liquid level value, it outputs a switch signal to control the opening and closing of the solenoid valve, thereby achieving the requirement of quantitative control of the liquid level height.

Detailed information on liquid level control equipment:

1、 Technical solution

1. Through the WDK type quantitative control cabinet of Shanghai Longkui Company/Liquid level high and low control equipmentThe liquid level control instrument inside the box receives signals from the liquid level gauge to control the opening and closing of the solenoid valve, thereby achieving the desired liquid level value

2. WDK type liquid level quantitative control device/Liquid level high and low control equipment(Liquid level control cabinet)/The box receives a current (4-20mA) signal to measure the liquid level value and outputs a switch signal to control the solenoid valve

3. The liquid level meter measures the liquid level value and transmits it to the quantitative control box through a 4-20mA analog signal

4Liquid level high and low control equipment/Liquid level quantitative control device/The quantitative control instrument in the liquid level control device/liquid level quantitative control box can achieve the requirement of quantitative control of liquid level height by manually setting the liquid level value (note: the set liquid level value must be within the total range). When the liquid level value reaches the set liquid level value, the liquid level meter outputs a switch signal to control the electromagnetic switch

2、 Operating instructions

1. WDK liquid level control box: contains digital tube display quantitative control instrument/liquid level controller/liquid level control display instrument, internal control circuit and other components, external control buttons and indicator lights, etc

2 WDKLiquid level high and low control equipmentLiquid level control device components: quantitative control box, liquid level gauge, cut-off equipment

3. WDK liquid level device cut-off device: It can be an existing power equipment in the pipeline, such as a pump, or a later installed solenoid valve, electric valve, flow valve, etc

4. Process control:Liquid level high and low control equipmentLiquid level quantitative controllerAfter receiving the signal from the liquid level gauge (4-20mA), the liquid level control instrument completes the conversion of the liquid level value inside, and sets the required quantitative control box inside the control instrument. When the liquid level value displayed by the quantitative control instrument reaches the set quantitative liquid level value, the quantitative control instrument outputs a switch signal. At this time, the switch signal is used to control the cut-off equipment installed on the pipeline through a relay or contactor, thereby achieving the effect of quantitative control

3、 Product Features

1. As long asLiquid level high and low control equipment/Liquid level control cabinet/liquid level control boxComposed of a flow device and a cutoff device, the structure is simple and the cost is low

2. The control circuits and components inside the control box are customized according to the flow meters and equipment required by the customer. The signal lines are easy to connect and generally do not need to be adjusted upon arrival at the site

3The high and low liquid level control equipmentThe control panel is equipped withThe "start", "stop", and "reset" buttons are displayed with a "status indicator light", making the display intuitive, easy to operate, and easy to learn

Start: One click start (note: After the customer sets the desired liquid level value, simply press the start button and the entire system will automatically start)

Stop: When the customer sets the value and presses the start button, the system is running. If the customer needs to temporarily stop, press the stop button to temporarily stop the entire system

4. The liquid level quantitative control instrument is a fully Chinese LCD display, and the quantitative control value can be changed as needed each time. It only needs to be operated inside the quantitative control instrument

4、 Indicate
