The HS-2000 External Ultrasonic Tank Level Sensor is a Non-invasive/non-contact device that accurately measures liquid levels in sealed tanks. To measure the liquid level in the tank by sticking an external sensor to the bottom of the tank. Its advanced technology and easy installation make it ideal for various liquids, including toxic or acidic ones.
Sino-Inst offers a variety of Ultrasonic Tank Level Sensors for industrial tank level measurement. If you have any questions, please contact our sales engineers.
External ultrasonic tank level sensor
HS-2000 External Mounted Ultrasonic Tank Level Sensor- (referred to as “external level gauge”). It adopts advanced signal processing technology and a high-speed signal processing chip. It breaks through the influence of container wall thickness. Realizes the height of the liquid level in the closed container True non-contact measurement.
The ultrasonic liquid level sensor (probe) is installed directly under the outer wall (bottom) of the container under test. Calibrate the outer wall of the probe. There is no need to open holes for the container to be tested, easy to install, and does not affect production.
It can accurately measure the level of various toxic substances, strong acids, strong alkalis, and various pure liquids in high-pressure airtight containers.
The HS-2000 External Mounted Ultrasonic Tank Level Sensor has no special requirements for the material of the liquid medium and the container. The explosion-proof design is adopted to meet the explosion-proof requirements.
Features of HS-2000 Ultrasonic Tank Level Sensor
- Non-contact measurement function ——– Ultrasonic sensor probe is external. No need to open a hole in the container to be tested.
- Auto-calibration function——–With self-calibration function. It overcomes the problem of reduced accuracy after the long-term use of traditional liquid level gauges.
- Infrared online debugging function——–Applicable to occasions where it is not suitable to open the cover for testing in dangerous situations. At the same time, it reduces the difficulty of debugging.
- Self-diagnosis function——–It has its own working status diagnosis function. It also has a hardware diagnosis function. It enhances the reliability and stability of the level gauge.
- One-key recovery function——–When the external measuring level gauge works abnormally, it can be restored to the normal state with one key through the debugger.
- Local display and remote transmission function——–The level gauge can not only display the level value on the spot in time. But also remotely transmit it to the control room through the signal line.

External Ultrasonic Tank Level Sensor Working Principle
The External Ultrasonic Tank Level Sensor adopts the sonar echo ranging principle. It overcomes the influence of the tank wall on the transmission of ultrasonic signals. It adopts advanced digital signal processing technology. It can truly realize non-contact, high-precision measurement of the liquid level in the tank.
The External Ultrasonic Tank Level Sensor can output 4-20mA standard signals or output the measurement results to the upper computer (or secondary meter) through the RS-485 interface. It can meet the automatic control of the system.

1.Medium’s Purity Degree
Liquids should not contain dense foam
There should be minimal suspended objects in the liquid, such as crystallized particles, etc.
There should be minimal precipitation in the tank, such as mud, sand, etc.
2.Tank Material：Carbon steel, stainless steel. Various hard metals. Glass fiber-reinforced plastics. Epikote, rigid plastics, ceramics. Glass, ebonite. Other composite materials.
3.Tank Shape：Spherical, horizontal and vertical tanks are permitted.
If you need to measure river water level, open channel level, etc. The Ultrasonic Liquid Level Sensor can be used for non-contact continuous level monitoring.

How to Choose an Ultrasonic Tank Level Sensor?
To choose a suitable Ultrasonic Tank Level Sensor, users need to understand their measurement conditions and needs.
- Are you measuring a liquid or bulk material?
- What is the size of the tank? What level measurement range do you need?
- Is the location classified as a Hazardous Location or Explosive Atmosphere?
- Point level or continuous measurement?
- Will the material coat or buildup on surfaces?
- Does turbulence, foam, or vapor occur at the surface of the liquid?
- What kind of output will you need?
- Installation location and installation size?
