Introduction
The IoT intelligent instrument produced by our company can be quickly connected to the cloud, realizing synchronous monitoring on computer and mobile App.It is suitable for real-time monitoring of liquid volume, pressure, positioning and other data of on-board gas cylinders powered by LNG and hydrogen energy, real-time alarm reporting, and computer terminal view of vehicle movement track. It has LCD display of intelligent transmitter and remote calibration and configuration of intelligent liquid level meter. The driver's position in the car can be connected to display instrument or instrument panel, and the liquid volume in the vehicular cylinder can be managed visually. The new Model MTU of vehicular cylinder can also realize mobile phone NFC calibration instrument, cloud storage calibration data, cloud download backup data. It is convenient to replace the liquid level meter. It has effectively strengthened the monitoring of vehicular cylinder, reduced the input cost, improved the operation safety and convenience of  new energy vehicles, and improved the work efficiency of personnel.

2. Remote calibration of intelligent level gauges (without memory cable, no need for a communicator). As shown below:



3. The intelligent level gauge will wirelessly connect the vehicular LNG cylinder into the network through the TeleDate module. The computer and mobile phone can remotely monitor and manage synchronously, realizing real-time monitoring of liquid level, pressure and position. Functions like liquid addition statistics, movement track map display, maintenance records, etc are clear at a glance. As shown below：




liquid level + pressure, NFC calibration, data cloud storage
