5.2 Transmitter Unit Installation
The transmitter unit is installed at the top of your water tank. Follow these guidelines for optimal performance:
- アンテナ： Ensure the antenna is positioned for clear signal transmission.
- Balance Bubble: Use the integrated balance bubble to ensure the transmitter is level for accurate readings.
- 取り付け: Secure the transmitter using screws through the designated bracket.
- センサーの配置: The ultrasonic sensor should have a clear path to the water surface. Ensure there is a minimum air gap of 0.5 meters (H1 height) between the sensor and the maximum water level.
- Tank Opening: The tank opening for the sensor should be at least 20cm in diameter (Ø > 20CM) to prevent interference from tank walls.
