产品介绍
霍尔微量计原理 / Principle of Hall Micro Flowmeter
通过检测叶轮转动，通过水流推动带有双极小磁铁的叶轮，由霍尔传感器在磁极为N级
或S级时，输出电压进行转换
By detecting the rotation of the impeller, the impeller, which is equipped
with bipolar tiny magnets, is driven by the water flow, and the Hall sensor
outputs a voltage for conversion when the magnetic poles are at the N or S poles.
应用场景 / Application Scenarios
此传感器适用于微小流量的检测，可以检测20ml/min的超小流量
This sensor is suitable for micro‑ flow detection and can measure ultra‑ low
flow rates as low as 20 mL/min.
1. 咖啡机/ Coffee Machine
在咖啡机的出水口安装霍尔流量计，配合咖啡机内置的配方，当用户在选择口味后，按
照配方进行出水量、出糖量、出奶量和出咖啡量进行控制。给用户更好的使用感受和口
味选择多样化。
Install a Hall flowmeter at the outlet of the coffee machine, combined with
the built-in formula of the coffee machine. When the user selects a flavor,
press Control the water output, sugar output, milk output, and coffee output
according to the formula. Provide users with a better user experience and
experience Diversified taste choices.
2. 果汁机/ Juicer
进行果汁出量的控制
Control the juice output
3. 热水器/ Heater
在用户进行出热水的操作时，检测到出水口有流量变化，此时可以做断电保护
When the user performs hot water operation and detects a change in flow rate
at the outlet, power-off protection can be implemented
4. 洗衣机/ Washing Machine
在洗衣机加洗衣液的地方安装，用户使用不同模式，出洗衣液的多少可以调节
Installed at the place where the washing machine is filled with laundry
detergent, the amount of laundry detergent can be adjusted by the user using
different modes
5. 饮水机/ Water Dispenser
用于控制出水量
Used to control the water output
6. 宠物喂食机/ Pet Feeding Machine
可以定量进行宠物补水的控制
Can quantitatively control pet hydration
7. ····需要计算流量或流速的产品
Products that require flow or velocity calculation
产品优点 / Advantage
1. 传感器可检测微小流量，其可以在20ml/分钟的流量下进行检测。
The sensor can detect small flow rates and is capable of measuring flow
at 20 ml/min.
2. 安装方便，可以直接替代传统流量传感器
Easy to install, can directly replace traditional flow sensors
3. 使用便捷，传感器的宽电压范围无需进行电压的转换
Easy to use, the wide voltage range of the sensor does not require voltage
conversion
4. 精度高
High precision
5. 可以监控不透明液体
Can monitor opaque liquids
