Radar level meter adopts the mode of transmitting – reflecting – receiving. The antenna of the radar level gauge emits electromagnetic waves, and the radar waves travel at the speed of light. After these waves are reflected by the surface of the measured object, they are received by the antenna. The time from transmission to reception of the electromagnetic wave is proportional to the distance to the liquid surface.

Ultrasonic level meter can be widely used in chemical industry, water treatment, water conservancy, food, grain and other industries level measurement. The product has the characteristics of safety, cleanliness, high precision, long life, stability and reliability, easy installation and maintenance, simple reading and so on. Ultrasonic level meter is a digital level meter controlled by microprocessor.

The ultrasonic level meter is mainly used to measure the liquid level of the liquid medium, but it can also be applied to the level measurement of some solid media. These liquid media can include water, oil, chemical liquids, solutions, etc. The working principle of the ultrasonic level meter is to determine the distance between the liquid surface and the sensor by transmitting the ultrasonic pulse and measuring the time of its echo, so as to calculate the liquid level.

Ultrasonic level meters are usually widely used in industrial fields, such as chemical, pharmaceutical, water treatment, food and beverage production. Their non-contact measurement characteristics make them suitable for use in environments where corrosive or hazardous liquid media may be present, as well as where remote monitoring is required. This level measuring device provides accurate measurements while avoiding direct contact with the medium, reducing the risk of contamination and maintenance.

Ultrasonic level meters offer a range of advantages across various industrial applications, providing reliable and accurate measurements for liquid and solid level monitoring. One significant advantage is their non-contact measurement capability. Unlike traditional level measurement methods that require direct contact with the substance being measured, ultrasonic level meters use sound waves to determine the distance between the sensor and the material’s surface. This non-intrusive nature eliminates the need for physical contact with corrosive or hazardous substances, ensuring a safer and more versatile solution for a wide range of industries.

Troubleshooting of ultrasonic liquid level meter:

1. Instrument specifications (determine power supply form and range)

2. Use temperature and pressure

3. Measured substance (liquid, solid, name)

4. Installation site (indoor and outdoor)

5. Container structure (closed container, pool, bunker, height, width, container material)

6. Installation method and position (flange, support, opening size, flange nozzle length, whether to add pipe)

7. Fault symptoms (correct level value, incorrect value displayed, installation height, etc.)

Ultrasonic level meter  is based on the Time-of-Flight principle.  A sensor emits ultrasonic pulses, the surface of the media reflects the signal and the sensor detects it again.  The Time-of-Flight of the reflected ultrasonic signal is directly proportional to the distance traveled.  With the known tank geometry the level can be calculated.

Ultrasonic level meter for continuous level measurement of liquids or bulk solids.  Typical applications are the measurement of liquids in storage tanks or open basins.  The sensor is also suitable for the detection of bulk solids in small vessels or open containers.  The non-contact measuring principle is independent of product features and allows a setup without medium.
