Who is it suitable for and how to use it?

This ultrasonic liquid level sensor is ideal for farmers, business owners, and homeowners who want to monitor the level of wastewater, fuel, water, or grain tanks remotely. The sensor is mounted in the middle of the tank, avoiding the area above the liquid inlet, to ensure accurate measurements. When used with a smart plug, it can automate the control of a water pump based on the tank level.

Buyer questions

Question: What is the maximum distance the sensor can measure?
The sensor detects the liquid level from 40 cm to 8 meters in height. This allows it to be used in both small and large tanks, including fuel tanks and grain bunkers.

Question: How does the sensor connect to the internet?
The sensor connects via the "Tuya Smart" or "Smart Life" app, using Bluetooth and a 2.4GHz WiFi network. The distance to the router without obstacles can be up to 30 meters.

Question: Can the sensor be mounted on a pipe?
Yes, but the pipe must be solid, without any connections, and clean inside. Impurities or connections may distort the ultrasonic liquid level sensor's measurement results.

The TLC2404 ultrasonic liquid level sensor is a reliable solution for remote monitoring of tanks without contact with the material. It is suitable for industry, farms, and households where a convenient and accurate level control method is important.
