This intelligent bottle stopper is a patented technical product specially developed for measuring the liquid level and temperature of liquid nitrogen tanks made of aluminum. It uses single chip computer technology from highly integrated liquid level sensors and platinum resistance temperature sensors to measure the liquid level height in the tank and the high point temperature in the mouth of the tank to display the data in real time.
The system adopts ultra-low power solutions. The built -in battery can keep the instrument running for 1-2 years. The system adopts a simple and efficient single button mode, which can switch pages and adjust parameters. When the parameters are set up, the data can be saved automatically for about 15 seconds.
