4. Function:

• It is suitable for non-metallic pipeline/container. There is no need to place inside the pipeline/container. Directly attached to the surface of the pipeline/container.
• It supports adjustable sensitivity. Turn the potentiometer to adjust the sensitivity. Counterclockwise rotation increases sensitivity.
• It is no need to contact with liquid directly.
• It will not be damaged by corrosive liquid such as strong acid and alkali.
• It is not affected by impurities such as scale.
• It can check boiling water.
• It is a purely electronic circuit but not mechanical.
• It can penetrate a variety of non-metallic containers such plastic, glass, ceramics, acrylic, rubber and so on.
• It supports the detection of liquids, powders, granular substances.

5. Pin definition:

• Brown: It is VCC. Connect to positive pole at 5V.
• Blue: It is GND. Connect to negative pole at 5V.
• Yellow: It is signal output terminal.
• Black: It is used to select output type. Connect to VCC is used to set PNP output type that the Yellow output can connect to relay. Connect to GND is used to set NPN output type that the Yellow output can connect to Lamp.

6. Using Steps:

• Connect work power supply DC 5V.
• Attach the sensor probe to the surface of the pipeline/container.
• Change the liquid in the pipeline/container or move the sensor and then wait for the indicator to light.
• It is right if indicator turn ON.
• Remove power supply and connect controlled device at output.
• Re-connect work power supply.

7. Note:

• It can't be in direct contact with liquid and it can't be placed inside liquid.
• It can only indicate the result of the test by LED. Buzzer alarm is not supported.
• It can't test metal pipeline.
• Avoid installation at the water inlet and outlet.
• Please read use manual and description before use.

8. Application:

• Water tower
• Sewage treatment
• Drone irrigation
• Medical equipment
• Aquarium
• Smart Appliances

9. Frequently asked questions:

Why is there no indicator no matter how to adjust sensitivity after power ON?

• The power supply is not connected correctly. Please check the power supply wire or replace new wire.
• Make sure connect DC 5V.
• Make sure positive and negative pole of power supply is right.
• Maker sure your power supply is work.
• Increase sensitivity.

Why does the LED indicator keep saying ON?

• Sensitivity is too high, please reduce sensitivity.
• Impurities inside the pipeline form deposits or near metal parts. Please clean up impurities and keep away from metal accessories.
