Electronic Flow sensor / Flow switch / Flow Meter
1. Thoeory:
Based on the thermal principle, the closed probe contains two resistors, one of which is heated as a detection resistor and the other unheated as a reference resistor, and when the medium flows, the heat is carried away from the heated resistor. The resistance value is changed and the difference between the two resistors is used as a basis for determining the flow rate.
2. Product feature:
2. Product feature:
No moving parts, maintenance-free, easy to install, a model for a variety of pipe diameter requirements, switching volume continuously adjustable, very low pressure loss, compact structure LED display flow trend and switching status.
3. Application
3. Application
Pneumatic-hydraulic dual-purpose type, can be used in pneumatic and hydraulic systems, can be used for circulating water, cutting fluid and lubricating oil flow monitoring, as well as pump idling protection.
Installation Instructions
For flow switches with outputs in the form of PNP, NPN and relays, the meaning of the LED indication is as follows:
Red on Flow rate below set point (transistor does not conduct/relay does not operate)
Flow rate is equal to or higher than set point (transistor energized/relay operates)
Yellow and green lamps are on The extent to which the flow rate exceeds the set point (green lamps 1, 2, 3 or 4 are on together with the yellow lamp)
1. Install the flow switch so that the medium flows at the flow rate that needs to be detected, adjust the potentiometer so that the first green LED lights up just right and the switch is released when the flow rate falls below the current value. If you want to make the switch point is smaller than the current flow rate, you can adjust the potentiometer so that the green LED more bright.
2. If you need to adjust the size of the flow rate, the specific adjustment steps are: unscrew the plastic screws, will be a screwdriver, inserted into the bottom of the product, clockwise adjustment knob, the more the green LED lights the flow rate of the larger, counterclockwise adjustment knob, the less the green LED lights the flow rate of the smaller!
