Description

 

Electronic Intelligent Water Flow Meter 1/2” External Thread Digital Display Flow Sensor with M8 Temperature Probe

Specification:
- Pin connection:
  Red: IN, for positive
  Yellow: OUT, for signal output cable
  Black: GND, for negative
- Model: YF-B7
- Water pressure resistance: <1.75MPa
- Precision: ±3 ~ 5%
- Flow pulse characteristic: F = (11 x Q)±3%; Q=L/Min
- Flow range: 1 ~ 25LMIN

Note:
- It can not be used for steam, corrosive or viscous liquids.
- Please do not disassemble the product when any quality abnormalities are found.
- When using air to dry the residual water inside the sensor, pay attention to the output signal being less than 150HZ, and the impeller cannot rotate at high speed without water.

Display Instruction:
- Temperature: the temperature display range is -99°-999°. Unit C is Celsius and F is Fahrenheit. Temperature unit can be switched by pressing the "+" key.

- Use of time / flow rate display:
  When there is water flow, it will automatically jump to the flow rate display, and when there is no water flow, the total time will be displayed (it only display time for water pressure mode). Total time unit DAY indicates days, HRS indicates hours, and time units can be switched by long pressing the "+" key.

  The flow rate unit LPM represents "liters per minute", GPM represents "gallons per minute", and can be switched by briefly pressing the "-" key.

  Display the current interface number in other interfaces: 00 represents the K value setting interface (K SETING).

- Battery indication: The battery reminder icon will display and flash when the battery level is low, prompting the user to replace the battery. It will not display when the battery is sufficient.

- Faucet animation: When water is detected passing through, the faucet animation will start displaying water droplets.

- Display of total water consumption and flow rate: The total water consumption is expressed in liters in units of L and gallons in units of gal. When the total water consumption is less than 10000L (or GAL), it will be accurate to two decimal places. When the total water consumption is greater than 9999.99 L (or GAL), the value after the decimal point will be hidden. The maximum measurement is 999999L (note: based on liters, if the unit is set to GAL, it will be cleared to 0 after reaching 999999L, that is, cleared to 0 after reaching 219969GAL). If it exceeds the limit, it will be remeasured from 0.

- K setting: The K setting character will be displayed when entering the K setting interface. K value is used for error adjustment. Different flow meters have different K values.

- Total flow characters: When the system is operating in flow meter mode, the total flow character will be displayed on the main interface.

Settings and interface instructions:
- Main interface and settings under the main interface:
  The main interface will display characters such as TOTAL, total water consumption, temperature, and total usage time.

  Long press and hold the "SET" button on the main interface to set the total usage time. After long pressing the "SET" button, the first digit of the total usage time will flash, while short pressing the "+" button will add 1 to the flashing digit; Short press "-" to reduce the number flashing by 1; Short press the "SET" key to switch to the next digit. After setting, long press the "SET" button to save the settings.

  Note: When setting the total usage time, it is set in hours by default. The total usage time in the flow meter mode and the total usage time in the water pressure gauge mode are independent.

- Settings in the K value setting interface and K value setting interface:
  When the system is working in flow meter mode, short press the "SET" button once on the main interface to jump to the K value setting interface.

  The character "K SETTING", interface number 00, and K value will be displayed in the K value setting interface.

  Long press and hold the "SET" button in the K value setting interface to set the K value. After long pressing the "SET" button, the first digit of the K value will flash, while short pressing the "+" button will add 1 to the flashing digit; Short press "-" to reduce the number flashing by 1; Short press the "SET" key to switch to the next digit. After setting, long press the "SET" button to save the settings.

Others:
- System sleep mechanism: When using the battery interface for power supply, in order to save energy and improve battery life, this system will enter a sleep state when unmanned and without water flowing. After entering the sleep state, the display screen will automatically jump to the main interface and maintain the display function. Automatically wake up and enter the metering state when there is water flow.

- Reset the total water consumption (reset the total amount): In the interface Total, long press the SET key, the number flashes. Press the up or down (+, -) key, adjust the number to 0, press SET to switch to the next digit and adjust to 0, and long press SET to save. (integer is cleared to zero, and the number after the decimal point of the total amount is not cleared to zero)

Package Included:
- 1 x Flow Meter

Note:
- Battery is not included.
