Scheme One: Monitor by wireless digital display liquid level meter
Wireless digital display liquid level meter for low temperature gas cylinders belongs to mass liquid level meter, which is a measuring instrument for low temperature medium researched and developed by our company. It can measure and display the mass of the low temperature medium in the gas cylinder directly, accurately in real time. (It can also display mass percent). The measuring result will not be influenced by different medium components and changing temperature. It has advantages of high measuring precision, convenient installation and no wiring. It has been widely promoted in the industry market.
The liquid level meter is composed of mass sensor, digital display indicator (mass percentage indicator) and other components. See diagram below.

Scheme Two: Liquid level gauge monitoring through IoT
DeleeTech focuses on R&D and manufacturing of measurement sensors, making IoT instruments applied in many industries, and providing solutions for industrial upgrading of intelligent equipment. IoT instruments can monitor assets through computer and mobile phone synchronously. Users can gather information such as liquid level, pressure, location and temperature of the tank container on real time and set alert value on their own to realize real-time alert. Thus, achieve effective monitoring of the tank container, cost reduction, safety improvement and productivity promotion.
Multiple wireless remote liquid level gauges can be connected wirelessly through a relay.
