Product Description
A radar level meter is a device used to measure the level of liquids or solids in a container. It operates based on the
principle of radar technology, offering high accuracy and reliability in level measurement. Here is a detailed introduction.
Working Principle
The radar level meter emits high - frequency electromagnetic waves towards the surface of the medium in the container. These waves
travel at the speed of light. When the waves encounter the surface of the medium, they are reflected back to the radar level meter.
The meter measures the time it takes for the electromagnetic waves to travel from the transmitter to the medium surface and back.
Since the speed of light is known, the distance between the radar level meter and the medium surface can be calculated based on
the time - of - flight principle. By subtracting this distance from the known height of the installation position of the meter, the level of the
medium in the container can be obtained.
Advantages
High accuracy: It can achieve high - precision level measurement, with an accuracy of usually within ±1 mm. This is very important for
some processes that require precise control of the medium level, such as in the chemical and pharmaceutical industries.
Wide measurement range:It can measure the level of media in containers of different sizes and shapes, with a measurement range
that can reach tens of meters.
Strong anti - interference ability:The radar level meter is not affected by the physical and chemical properties of the medium, such as
temperature, pressure, density, and viscosity. It is also less affected by the external environment, such as dust, steam, and noise,
ensuring reliable measurement results.
Easy installation and maintenance: It does not require complex installation and calibration procedures, and can be installed and
commissioned quickly. In addition, the maintenance workload is small, which can reduce the cost of use and maintenance.
Applications
Petroleum and chemical industry: It is used to measure the level of various liquid raw materials, intermediates, and products in
storage tanks and reactors, such as crude oil, gasoline, diesel, and chemical reagents.
Food and beverage industry: It is used to measure the level of liquids such as water, juice, and beer in storage tanks and production
equipment to ensure the normal operation of the production process and the quality of products.
Power industry: It is used to measure the level of water in boilers, cooling towers, and water storage tanks to ensure the safe and
stable operation of power generation equipment.
Mining and metallurgy industry: It is used to measure the level of ore pulp, tailings, and other media in mining and metallurgical
production to optimize the production process and improve production efficiency.
