Excellent Radar level measurement factory
Radar level transmitter factory China: Radar level meter adopts non-contact measurement, and has the advantages of high measurement accuracy, not affected by process conditions, easy to install and easy to maintain, so it is widely used in offshore oil platforms in recent years. Today, we would like to take you through several actual cases in offshore oil platform to understand the reasons and solutions of the radar level meter’s measurement value jumping. The first case was an oil field where the radar level meter in the left crude tank jumped to full scale several times during production. A sealed metal cover was used to cover the main body of the sensor, and during the test, it was found by connecting the radar level transmitter that the closed metal cover would result in more false signals throughout the measurement range, and the overall noise line would rise.

Temperature Compensation- Precision in Any Environment Another advancement in guided radar level measurement technology is the incorporation of mechanisms that compensate for temperature variations. Temperature fluctuations in microwave module circuits can lead to inaccuracies in measuring levels. To tackle this challenge, radar level measurement systems have implemented creative solutions. A crucial aspect of these advancements involves allocating a portion of the radar transmission pulse as a reference pulse. This reference pulse serves as a benchmark for comparing measurements enabling temperature calibration. When temperature changes occur the radar sensor can adjust its measurements accordingly ensuring that environmental conditions have no impact on accuracy. This temperature compensation feature is particularly valuable in applications where significant temperature shifts are common. Industries dealing with temperatures or processes prone to variations, such as petrochemical or food manufacturing sectors, rely on precise measurements. Radar sensors equipped with temperature compensation mechanisms rise to the occasion by delivering reliable results despite changing conditions.
If the radar level meter is unreasonably selected, the interference echo cannot be handled well, and the reliability of the instrument will be reduced. Therefore, the following factors should be considered when selecting a radar level meter: Conductivity and dielectric constant of the measured medium. The measured medium is a conductive liquid or a liquid with a dielectric constant above 4. Generally, a common radar is selected. Liquids with small dielectric constants (dielectric constants below 2) and some conductive solids often use precision radars or guided wave radars due to the large amount of interference echoes.
With the continuous advancement of science and technology, radar water level meters have been used more and more. It has the advantages of low cost, high stability, flexibility, high reliability, low power consumption, convenient parameter setting, safe and simple maintenance, etc., and has important promotion value. Today, the editor will take you to a simple understanding of radar water level meter. Radar water level meter is a kind of measurement equipment introduced from abroad in recent years. The water level meter has mature technology, high measurement accuracy, easy installation, and is not restricted by environment and geography, so it has been widely used.
Any appreciable gain in boiler feedwater achieved through the process reduces the amount of energy (fuel) required at the boiler— in fact, every 10.8°F (6°C) rise in boiler feedwater amounts to a one percent savings in fuel cost. Inadequate level controls can inhibit the deaeration process (level too high) or reduce/shutdown feedwater flow to the boiler (level too low). The former affects hardware longevity and efficiency, while the latter risks production losses and possible damage to pumps.
In the process of cement production, material level detection and material level alarm control play an important role from mining and crushing to storage and packing of finished cement. But because of the complex working conditions of cement plant, radar level meter has no small difficulty in measuring. Today, I would like to talk with you about specific difficulties and solutions. First cement plant material for measurement in the dust under the condition of particularly large, especially some pneumatic feed bin, involves the kinds of materials, material particle size is differ, dielectric constant is different also, such as broken limestone, raw meal, clinker, fly ash, coal, cement, the level of the bunker, it is very difficult to accurately measure Especially fly ash bin with low dielectric constant.

The radar level gauge works by electromagnetic waves. Its working principle is to measure the specific liquid level by transmitting electromagnetic waves to the measured target. After the electromagnetic waves are emitted, they are reflected by the medium. For the radar level gauge, its key function is to ensure that it can transmit magnetrol guided wave radar signals smoothly. In our industrial production site, interference often occurs, so which interference sources will affect the measurement of the radar level gauge? let’s see.
When the distance between the liquid level of the measured medium and the electromagnetic wave transmitter is less than 4m, the guided wave radar is selected. If the distance between the liquid level of the measured medium and the electromagnetic wave transmitter is greater than 4m and less than 35m, select the guided wave radar with the guided wave cable. When the distance between the liquid level of the measuring medium and the electromagnetic wave transmitter is greater than 35m, or when the liquid level of the measuring medium is high temperature, high viscosity or solid liquid level, the air-shooting radar should be selected.
Product features: Large display range, wide range of use, suitable for low temperature, medium temperature, high pressure occasions. It can be matched with remote transmitter output 4-20MADC standard signal to realize remote display of liquid level guage. It can also be matched with liquid level switch to realize liquid level control. Generally speaking, the material level feedback is inaccurate and untimely, which is very prone to explosion events, and there is a greater safety risk. Therefore, the requirements for the radar level meter are very high, but the radar level meter often has abnormal material level jumps or falls, or even crashes, resulting in large errors in material level measurement, which brings trouble to production and sales.
