Product description
When the float goes up and down along the fixed support or shaft under the liquid buoyancy and swings up and down, the permanent magnet at the end of float fixed shaft swings accordingly under lever function, which consequnetly drives the micro switch in the junction box to move and output the on or off signal for alarming or remote control.
Installation method:
A. Keep the electrical interface of the junction box downward, please choose anti-corrosive type sl80/sl81 for acid and alkaline liquids
B. Please keep the float and the linkage rod away from the connection tube

Product Description
WFS10 Differential pressure flow switch
Overview:
The WFS10 differential pressure flow switch was designed for OEM customers to control flow accurately. It can be used in plumbing system when it is necessary to make sure the pressure difference between two points does not exceed or drop below a specific value. The setting value can not be changed, which can ensure the flow setting value can not be changed.
Features:
Easy to install
Good stability
Adjustable ranges
Accurately control flow
No resistance effect on water system
OEM capabilities include external adjustment knob with or without reference scale
Monitoring and application:
The pressure difference will increase with filtering, switch is on and output a signal when reached the pre-pressure value. If it automatically clean, the signal would be transmitted to controlling disk and then the controlling disk start to clean and open the waste valve. If worker to clean, the warning signal will be supplied.
Pump status and feed back to automatic controlling system:
The pressure difference is stable when the flow is constant, it would be changed when the system resistance is changed. The relation of pressure difference and flow, can refers to the pump performance data. So the differential pressure flow switch used for pump monitoring as well as the minimum flow control. When the actual pressure exceeds the set value, the switch output a dry contact signal for controlling system to indicate the pump has flow. The status light will indicates the pump status if it has.
Heat exchanger flow controlling
The differential pressure flow switch used for flow controlling is one of the most important application in HVAC system. It is the best substitutes of target type differential pressure flow switch. The reset flow is the minimum value used to check whether satisfy the requirement or not. The disconnect flow is protected instrument from decreasing flow. Following we take plate and extension-type heat exchanger and shell and tube type heat exchanger examples to introduce the characteristics of differential pressure flow switch.
Plate and extension-type heat exchanger
Plate heat exchanger with compact size and high heat transmission performance, has been widely used in cooling as evaporator and condenser. It is necessary to prevent plate heat exchanger from frost damage. A great deal of experimentation show that there is a possibility of freezing when the current flow less than the rated flow about 50%, so it is important to keep the current flow not less than 50% of rated flow. The pressure of 50% rated flow is the protection value of plate type heat exchanger, according to this value to choose differential pressure flow switch. We suggested to buy the fixed set point switch to ensure the value is right(the pressure difference can be tested by our professionals)
Shell and tube type heat exchanger
Shell and tube type heat exchanger used in cooling as evaporator and condenser. The
unstable flow directly influence the mainframe., so it is important to control the flow to ensure mainframe work normally. The 70% pressure of rated flow is the lower limit of protection value, we can obtain it according to the pressure and flow curve or measure in scene. You can consult the professionals of the ACOL for specific method. We suggest to buy double set points adjustable differential pressure flow switch, one of them can be used to indicate the heat exchanger cleaning status. Set the reasonable pressure difference and choose the status light, when the waste is overmuch the status light is on to remind the customer to clean heat exchanger. Avoid energy waste because of the heat transfer effect drops and influence main engine work.
