Product Usage
Step-by-Step Installation Process:
- Choose Installation Site:
Select a location with stable water flow, minimal interference, and ensure the sensor is fully submerged.
- Mount the Sensor:
Secure the sensor using mounting brackets and position it correctly for accurate measurements.
- Connect Power and Data:
Attach the power source (3.3–5V or 5–24V) and configure the output signal (RS485, 4-20mA, or voltage signal).
- Calibrate and Test:
Calibrate the sensor, connect it to the monitoring software, and test its functionality to ensure accurate data transmission.
Choosing the Installation Site:
Easy Access: Select a location that allows convenient access for maintenance, calibration, and inspections.
Stable Water Flow: Place the sensor in areas with consistent water flow, avoiding turbulent or stagnant zones.
Interference-Free: Ensure the site is away from electrical noise, debris, or physical obstructions that could affect performance.
Proper Submersion: Install the sensor fully submerged in water, avoiding areas with fluctuating water levels or extreme conditions.
