User Manual for Immax 07543L Smart Ultrasonic Liquid Level Sensor

Quick guide from the manual

The Immax 07543L is a WiFi-enabled ultrasonic liquid level sensor designed for monitoring tank levels. To ensure accurate readings, the sensor must be installed perpendicular to the liquid surface and away from obstacles like water inlets or partitions. The device is configured and monitored via the Immax NEO PRO app.

Installation

Proper installation is critical for accurate ultrasonic detection:

• Drilling: Drill a 55 mm hole in the tank lid or top surface.
• Placement: Place the sensor over the hole. Ensure the ultrasonic sensor face is not obstructed.
• Sealing: Place the provided gasket between the sensor and the tank surface to ensure a proper seal.
• Securing: Fasten the sensor to the tank using screws.
• Positioning: The sensor must be held perpendicular to the liquid level. Avoid installing near water inlets or partitions, as these can cause false echoes.

App Pairing

1. Connect the sensor to the power supply.
2. Press and hold the button for at least 5 seconds to activate pairing mode (LED will flash).
3. Open the Immax NEO PRO app on your mobile device.
4. Ensure your mobile device is connected to the same 2.4GHz WiFi network you intend to use for the sensor.
