With the development of modern industry, the storage, transfer, and processing of various media require monitoring of temperature, pressure, level, flow, and other parameters, among which radar level meter, as a high precision and high-reliability level measuring instrument, is increasingly used in industry. This article will discuss the application and measurement difficulties of radar level meters in coolant storage tank measurement, and analyze them with actual cases.
Coolant is a medium for heat dissipation and cooling in certain mechanical equipment or industrial processes through the heat absorption effect on the flowing medium, which is widely used in automotive, steel, electronics, pharmaceutical, and other industrial fields with a wide range of applications and more specific uses.
In the measurement of the coolant storage tank, considering the lower temperature, high viscosity, and chemical reaction of the liquid, it is necessary to use the liquid level measurement means with high reliability and strong anti-interference ability to carry out accurate level measurement and control.
Radar level meter achieves accurate monitoring of liquid level measurement through changes in reflection, refraction, and attenuation of high-frequency electromagnetic waves.
Its advantages are anti-interference, strong reflection ability, and not being affected by the physical properties of the liquid, which provides an ideal solution for the level measurement of coolant storage tanks. In practical application, the radar level meter is especially outstanding for the measurement of coolant with high viscosity and complex medium. There are many challenges and difficulties in the level measurement of coolant storage tanks.
As follows: the temperature is too low when the sensor impact: for coolant and other lower temperature liquids, especially in extremely cold climate conditions, may lead to equipment failure; metal background caused by interference impact: many level meters will appear metal interference problems, because the coolant storage tank is usually made of metal material, this is particularly obvious for the radar level meter; level changes lead to interference: many coolants Many coolant storage tanks will have irregular level changes, which will easily cause interference with the radar level meter, and attention should be paid to standardized management and monitoring of level changes
In the level measurement of a large coolant storage tank in a steel plant, the level meter model selected was not applicable, resulting in low accuracy and frequent error disturbance. Steel production was directly affected.
To solve the problem, a high-precision radar level meter was replaced and debugged, and the mechanical failure and error problems were completely solved, ensuring the stability and accuracy of the coolant storage tank level measurement.
In addition, in the coolant storage tank in a power plant, there were frequent errors in the liquid level meter, which affected the accuracy of liquid level monitoring.
After several on-site field investigations, it was found that the level meter was obscured by some debris in the storage tank, resulting in problems with the signal reflection of the radar level meter, which led to the problem of decreasing the accuracy of the level meter. During the rectification, the engineers redesigned the internal structure of the tank so that the level inside the tank could be accurately sensed by the level meter. Since then, the level of measurement accuracy of the plant has been greatly improved.
Radar level meter provides an extremely ideal solution in the measurement of coolant storage tanks, but there are still some technical difficulties and application problems.
In practical applications, we need to consider a variety of factors such as liquid physical properties, tank conditions, and equipment quality in order to select the best and most reliable level measurement equipment.
At the same time, in the process of use, good maintenance is needed to ensure accuracy and long-term stability. Only in this way can the radar level meter get the best application effect in coolant storage tank measurement.
