SPECIFICATIONS

1、Product Features

1. The hand-held liquid level detector is suitable for the outer wall of non-metallic containers without direct contact with the liquid. It will not be corroded by strong acids and alkalis and other corrosive liquids, and will not be affected by scale or other debris.
2. Intelligent liquid level reference adjustment and liquid level memory function.
3. The detection is accurate and stable, and the boiling water level can be detected.
4. Pure electronic circuit structure, non-mechanical working mode, stable performance and durability.
5. High stability, high sensitivity, strong anti-interference ability, free from external electromagnetic interference.
6. Strong compatibility, penetrating various non-metallic containers, such as plastic, glass, ceramic and other containers, the sensing distance (container wall thickness) can reach 40mm; liquid, powder, and particulate matter can be detected.
7. Powered by 2 AAA batteries, the battery is cheap and easy to buy, with a NPN output at the end, suitable for docking with various devices to improve product flexibility.

2、Scope of application

1. Wine vessel inventory detection
2. Grain warehouse inventory detection
3. Inventory testing of the pharmaceutical industry
4. Filling inspection
5. Convenient water pipe shortage detection
6. Applicable to various non-metallic containers to detect liquid level inventory

4、Application conditions

Medium viscosity
When the dynamic viscosity is less than 10mPaS, it is measured normally. 10mPaS

6、Function and usage

1. On/off button: If it is not turned on, press and hold the “On/Off button” to display the sensitivity value; if it is turned on, press and hold the “On/Off button” to shut down.
2. "+" "-" key: Press the sensitivity "+" or "-" to adjust the sensitivity to a suitable value. When there is no liquid at the position to be detected, the buzzer will sound. Press the "+" and "-" keys to adjust the sensitivity appropriately to achieve more precision.
3. Indicator light: the blue light is on when the liquid is detected, and the buzzer sounds. The blue light goes out after leaving the test target. When the battery is low, the red light flashes once every 2 seconds.
4. Output protection: When the OUT terminal of the output port is directly connected to a voltage of 5-24V, it will automatically be forced to shut down.
5. Digital tube display: sensitivity adjustment range 1-100. When the battery voltage is lower than half, the digital tube will automatically reduce the brightness to save power consumption.
6. Automatic shutdown: automatic shutdown after 5 minutes when unmanned operation "+" "-" or no induction, to avoid forgetting to shutdown after use and running out of power.
7. Liquid detection: move down from the top of the container for detection. When liquid is detected, the blue indicator light will be on and the buzzer will alarm。

9、Product precautions

1. Pay attention to keeping the level gauge clean, try to prevent corrosion and avoid violent collisions and blows from other objects.
2. When the red indicator light flashes, please replace the battery in time.
3. Please use AAA batteries produced by regular manufacturers.
4. When not in use for a long time, please take out the battery in time to prevent battery leakage from damaging the sensor.
5. When you press and hold the power button and do not turn on, please confirm whether the battery voltage is normal and whether the battery is installed correctly.
6. Please do not disassemble the product privately. If you have any comments or suggestions, please contact customer service.
8. Please use the unit (or individual) to make reasonable use of the product based on its actual situation! The company is only responsible for the safety performance of this product, and is not responsible for any accidents caused by the user's (or individual) combination with other products.
