Flexible Accurate Radar Level Meter For Various Liquid Conditions

Description

Radar level meters have many advantages over traditional level measurement methods, mainly including the following aspects:

High accuracy:

Radar level meters use high-frequency radio waves for measurement and can provide very accurate level data, usually with an accuracy of millimeters. This makes it particularly advantageous in industrial applications that require high-precision level control.

Strong adaptability:

Radar level meters can adapt to various complex environments and liquid conditions. Regardless of the nature of the liquid (such as corrosive liquids, viscous liquids), changes in liquid density, temperature changes or pressure changes, radar technology can measure stably and is not affected by these factors.

Good stability:

Radar level meters are not affected by external environmental factors (such as temperature changes, atmospheric pressure changes, vibrations, etc.) and can operate stably for a long time. This makes it particularly suitable for industrial sites such as chemical plants, oil fields, food processing and other harsh environments.

High safety:

Since radar level meters are a non-contact measurement technology, there is no need for direct contact with the liquid during the measurement process. This not only avoids contamination of the liquid, but also reduces the safety risks of operators, especially for the measurement of hazardous chemicals.
Long life and low maintenance cost:

Radar level meters usually have a long life and are not susceptible to mechanical wear or chemical corrosion. Compared with traditional measurement methods, their maintenance cost is low, reducing downtime and maintenance costs.
Versatility:

Modern radar level meters usually have multiple functions, such as automatic calibration, remote monitoring, data logging and alarm functions. These functions make it more practical and reliable in industrial applications with a high degree of automation.
In summary, radar level meters have become one of the preferred technologies for level measurement in many industrial fields with their many advantages such as accuracy, stability, adaptability and safety.
 

A radar level meter is a device used to measure the precise position of a liquid or solid in a container. It uses radar technology to send and receive radio waves to determine the distance between the liquid or solid surface and the sensor. Here are some key features and working principles of radar level meters:

Working principle: The radar level meter sends high-frequency radio waves (usually microwaves or light waves) to the surface of a liquid or solid, and then receives the signal reflected back from the surface. By measuring the time difference between the sent and received signals, the height of the liquid level or the height of the solid can be calculated.

The GRD60 series sensor is a radar-type level measuring instrument with an upper limit of measuring distance of 30 meters. It can be used for level measurement in storage tanks, intermediate buffer tanks or process vessels, and outputs 4~20mA analog signals. Very short microwave pulses of very low energy are transmitted and received via an antenna system. Radar waves travel at the speed of light. The operating time can be converted into a level signal via electronics. A special time extension method ensures stable and accurate measurements over extremely short periods of time. Even if the working conditions are relatively complex and there are false echoes, microprocessing technology and debugging software can be used to accurately analyze the echo of the material level.

Ultrasonic level meters have a wide range of applicability in level measurement, and are particularly suitable for the following working conditions:

Non-contact measurement requirements:

Ultrasonic level meters are a non-contact measurement technology that avoids direct contact with liquids. This makes them particularly suitable for applications where the liquid needs to be kept clean, contamination is prevented, or the liquid has special properties (such as corrosive liquids).

Scenarios with large level changes:

Ultrasonic level meters can measure the liquid level stably and accurately, and can maintain good measurement accuracy even if the liquid level changes greatly. Therefore, it is suitable for storage tanks or containers with large level fluctuations, such as reactors, tanks, etc.

No medium limit:

Ultrasonic technology is insensitive to the type of liquid (water, chemicals, oil, etc.), density, and temperature changes, so it has a wide range of applications, including various liquid measurement needs in industry and the environment.

Long-distance measurement:

Ultrasonic level meters can measure liquid levels over long distances, and are suitable for scenarios where depth measurement is required, such as tall containers or deep wells.
Adapt to harsh environmental conditions:

Ultrasonic level meters usually have good anti-interference ability and can cope with harsh conditions such as vibration, temperature changes, high humidity, etc. in industrial environments to ensure stable measurement results.

Requirement for remote monitoring and automatic control:

Modern ultrasonic level meters usually support remote monitoring and automatic control functions, can be connected to data acquisition systems or intelligent devices such as PLCs, realize real-time data transmission and remote control, and are suitable for industrial applications with a high degree of automation.

In general, ultrasonic level meters are suitable for a variety of industrial and environmental level measurement needs due to their non-contact, high precision, strong adaptability and good environmental adaptability.

working principle

The antenna receives the reflected microwave pulse and transmits it to the electronic circuit. The microprocessor processes the signal and identifies the echo generated by the micro-pulse on the surface of the material. Correct echo signal identification is completed by pulse software, and the accuracy can reach millimeter level. The distance D from the material surface is proportional to the pulse time T:
D=C×T/2 where C is the speed of light. Since the distance E of the empty tank is known, the level L is: L=E-D
Set by inputting the empty tank height E (= zero point), the full tank height F (= full scale) and some application parameters. The application parameters will automatically adapt the instrument to the measurement environment. Corresponds to 4~20mA output.
