What kind of liquid level gauge is generally used in oil tanks? What are the characteristics of various liquid instruments?
Floats, radars, and differential level gauges can be used. The characteristics of the instruments are all listed in the instrument book. It would be too laborious to type too many.
It’s best to use a radar level gauge. You can try the E+H one, it’s very useful.
It cannot be generalized, it must be based on the nature of the liquid in the tank and the location of the upper temperature limit, etc. For example, if the temperature exceeds 400 degrees (but the storage tank generally does not exceed 400 degrees), magnetic flaps must not be used. Currently, many domestic manufacturers claim that their products can withstand 420 degrees, but the magnetism will disappear over time. If the storage tank is to be installed on a ship, special considerations must be made. In short, specific analysis of the specific situation
Oil tank level gauges generally include magnetostrictive, pressure, differential pressure, radar, ultrasonic, optical fiber and other level gauges. It depends on the medium in the oil tank. If there are multiple media, it is best to choose a magnetostrictive liquid level meter, which can measure the liquid level, interface and temperature of multiple media at the same time. It has high precision and good stability. Small oil tanks (tank height less than 6 meters) generally use stainless steel hard rod products, while large oil tanks (tank height more than 6 meters) use stainless steel flexible hose products. In addition, the corrosiveness of the medium must also be considered. The output signal is generally a digital signal and the transmission distance is relatively long. The measurement accuracy of pressure, differential pressure, radar, and ultrasonic is not high and unstable. The key is that it cannot be transmitted over long distances. There is a certain error between the value measured by the primary instrument and the value displayed by the secondary instrument. Especially in winter, problems caused by the influence of ambient temperature will be encountered during debugging. Fiber optic measurement has high accuracy, but if it is a variety of media, it cannot be measured accurately.
