Factors To Consider When Selecting A Level Measuring Instrument Suitable For The Main Oil Tank

The operation and development of a power plant is closely related to its equipment, including thermal power plants and thermal power plants. In thermal power plants, the main oil tank is one of the key equipment. When using a radar level gauge to measure the main oil tank level, the following aspects should be noted.

The liquid level of the main oil tank fluctuates greatly, and the start-up of the pump may cause significant changes in the liquid level and generate foam, which may interfere with the signal of the power plant radar level gauge and cause inaccurate measurement of the main oil tank level. Therefore, when selecting a radar level gauge, special attention should be paid to these interference factors.

In addition, the dielectric constant of the medium in the main oil tank is low (about 5 or less). Mediums with a small dielectric constant are suitable for guided wave radar level gauges, because the signal propagation path of the guided wave radar level gauge is single and the energy is concentrated, which is more suitable for the measurement of low dielectric constant liquids.

When installing a radar level gauge in a power plant, the following points should be noted: First, keep the level gauge away from the exhaust fan, return oil pipe, and oil pump to reduce interference. Secondly, after installation, other methods are needed to measure the original height of the tank and adjust the settings of the radar level gauge to ensure its accuracy.

Choosing the appropriate main tank level measuring instrument and installation method requires a combination of practical experience and expert advice to make a decision.
