1st. Overview
The intelligent non-contact small tube liquid level sensor (hereinafter referred to as the small tube sensor) adopts
advanced signal processing technology and high-speed signal processing chip, which is specially designed for the liquid
level detection needs of infusion tubes and industrial small tubes. The intelligent non-contact small tube liquid level
sensor can output high and low level signals at the same time, which can meet the needs of various occasions.
The intelligent non-contact small tube liquid level sensor uses the sensing capacitance of water to detect whether there is
liquid. When there is no liquid approaching the sensor, the sensor has a certain static capacitance to the ground due to the
existence of distributed capacitance. , when the liquid level slowly rises and approaches the sensor, the parasitic
capacitance of the liquid will be coupled to this static capacitance, making the capacitance value of the sensor larger, and
the changed capacitance signal is then input to the control IC for signal conversion, which will change the The
capacitance is converted into the change of a certain electrical signal, and then a certain algorithm is used to detect and
judge the degree of this change. When the change exceeds a certain threshold, it is considered that the liquid level reaches
the sensing point.
2nd. Scope of application
It is specialized in small tube application industries, such as medical equipment, medical infusion, biological liquid
detection, scientific research and teaching equipment, intelligent coffee machine, intelligent water dispenser, intelligent
electrical appliances, industrial small tube liquid level detection, etc.

High and low level output drive small relay (coil current ≤100mA) working principle:
When the liquid is sensed, the transistor will cut off and output a high level, and the relay will not pull in when it is
powered off;
When no liquid is sensed, the transistor is turned on and outputs a low level, and the relay is energized and pulled

7th. Installation method
Open installation holes on the panel where the sensor needs to be installed, and place the nuts in the upper and lower
fixing holes of the sensor or in the front and rear fixing holes to tighten to achieve up and down or front and rear fixing.
8th. Instructions method
When the sensor is working normally, put the liquid pipe into the pipe clamp wire groove. The instruction light is on
and the output is high, indicating that there is liquid passing through the current position of the tube. The indicator light is
off and the output is low, indicating that no liquid is passing through the current position of the tube .
9th. Sensitivity setting steps
The sensitivity of the product shall be calibrated in strict accordance with the standard before delivery; However, in the
actual use process, it may be necessary to fine tune the accuracy of sensitivity according to the on-site environment to achieve a
better experience effect.
1. Connect the sensor circuit as required.
2. Align the liquid level in the liquid pipe with the center of the sensor.
3. Turn on the power supply to power up the sensor.
4. After the mark line of the sensor (sensitivity calibration line) and the sensor gnd wire are shorted for about 1 second, the
mark line is converted from high level to low level, and the LED lamp of the sensor flashes to indicate that the sensor enters the
calibration state. After entering the calibration state, the mark line and the gnd wire are separated, and the calibration is
completed successfully when the LED lamp is always on.
Precautions: In normal use, the mark wire of the sensor(sensitivity calibration line) can only be suspended in the air and cannot
be connected to the positive or negative pole of the power supply.（It is recommended that the sensitivity calibration line be
connected to the negative pole (GND) through a switch. When setting the sensitivity, the switch should be closed, and it should
be disconnected in normal use.）
In the picture above, there is no liquid in the
water pipe at the detection level, and the
indicator light does not light up
In the picture above, there is liquid in the water
pipe at the detection level, and the indicator
light is on

13th.Precautions
1. The viscosity of the liquid medium to be measured
Normal measurement when dynamic viscosity <10mPaS. 10mPaS < dynamic viscosity < 30mPaS may affect the
detection. When the dynamic viscosity is more than 30mPaS, it cannot be measured because a large amount of liquid
adheres to the wall of the container.
2. Note: As the temperature increases, the viscosity decreases, and most high-viscosity liquids are more affected by
temperature, so pay attention to the effect of liquid temperature when measuring viscous liquids.
3. Pay attention to keep the level gauge clean, try to prevent corrosion and avoid violent collisions and blows from other
objects.
4. When installing outdoors, avoid direct sunlight on the main body of the level gauge, keep away from heat sources and
pay attention to ventilation. If the ambient temperature exceeds the rated temperature, corresponding cooling protection

measures should be taken.
5. When the ambient temperature is too low, the instrument protection box or other protective devices can be used for
antifreeze protection, and pay attention to keep the level gauge dry.
6. The sensor should be regularly inspected for maintenance. (The detection time interval is determined by the use unit
according to the specific situation).
