Instructions for Use:

1. Installation:

   • Ensure the sensor is installed in a location where it will not be exposed to direct sunlight or excessive heat.
   • Install the sensor in a straight section of pipe to ensure accurate readings.

2. Connection:

   • Connect the red wire to the positive terminal of the power supply.
   • Connect the black wire to the ground.
   • Connect the yellow wire to the signal input of your microcontroller or data logger.

3. Calibration:

   • Calibration may be necessary depending on the specific application. Follow the calibration procedure provided by the manufacturer or use standard methods applicable to flow sensors.

4. Operation:

   • Apply power to the sensor and allow it to stabilize before taking measurements.
   • The frequency of the output signal corresponds to the flow rate; higher frequencies indicate higher flow rates.

5. Maintenance:

   • Regularly check connections for any signs of corrosion or damage.
   • Clean the sensor periodically to prevent debris from affecting performance.
