External Mounted Tank Level Sensors
External Tank Level Indicator refers to an externally mounted level sensor. It is used to install on the outside of the liquid storage tank to measure the liquid level of the tank. When measuring with External Tank Level Indicator, install the ultrasonic probe just below the outer wall (bottom) of the container under test. No need to cut holes, easy to install. Does not affect on-site production. It can realize accurate measurement of various toxic substances and various pure liquids in high temperature and high pressure airtight containers.

Difficulties Existing in Liquid Level Measurement in Industrial Storage Tank Industry
Most liquid fuels used in industry, such as liquefied petroleum gas, gasoline, diesel, lubricating oil and other refined oils, as well as liquid chemical gases. For example: liquid ammonia, liquid chlorine, are stored in a high-pressure airtight container. In the production process, in order to ensure the safety of production, it is necessary to regularly measure the liquid level of the remaining liquid in the closed container.
Because these liquids are flammable and explosive. Using the traditional liquid level measurement method will cause damage to the tightness of the container. Safety accidents such as liquid leakage are prone to occur. In particular, after the storage tank has been built and put into service. It is hoped that another principle that is different from the existing level gauge will be added, and a level gauge with a different principle will be used. It’s hard for businesses to choose.

No holes – No damage the tank – External Tank Level Indicator
In response to the above problems, we designed and produced a new type of non-intrusive ultrasonic liquid level measurement system – externally attached liquid level gauge. This enables a truly non-invasive, non-contact measurement method.
Simply mount the measuring probe on the outer wall of the tank or container bottom. The reflection and transmission properties of ultrasonic waves are utilized. Realize the measurement of the liquid level inside the storage tank. The calculated liquid level value is displayed locally and a remote signal is output.
The meter can output measurement results to the control system via 4-20 mA analog signal, HART, RS-485 and other interfaces. At the same time, the data can also be sent to the Internet through wireless transmission via WIFI, GPRS and NBIOT.

Externally Attached Ultrasonic Oil Level Sensor – Trucks
Ultrasonic oil level sensor is an external sensor used to measure the liquid level height in tanks and containers.
The sensor uses the ultrasonic detection principle to measure the oil level（liquid level）, and then converts the measured height value into the oil volume value through intelligent processing, and then transmits the fuel volume data to the background supervision system through GPS to achieve the purpose of real-time monitoring of vehicle fuel consumption.
At present, the products are mainly used in the field of the Internet of Vehicles to monitor the changes in the internal oil level of the tank in real time, so as to realize the detection of fuel volume. It can be used to prevent oil theft, optimize operating costs, optimize driver driving behavior, assist statistical decision-making, etc. At the same time, this product can also be used in fields such as chemical industry, water conservancy, storage tanks and other fields with liquid level detection needs.
