Advantages: Not only the liquid level of the medium can be measured, but also the density, oil-water interface, average density and density distribution of the medium can be measured.
Disadvantages:
When the measuring medium has the characteristics of high viscosity, wall hanging and viscosity, the servo liquid level meter will produce large measurement error, which is not suitable for liquid level measurement of this kind of medium.
Supplement:
Radar level gauge:
Advantages:
Non-contact measurement can measure toxic media and viscous liquids.
Disadvantages:
When the volatility of the measuring medium is high, the radar level gauge will produce a large measurement error, which is not suitable for the liquid level measurement of this kind of medium. When the measuring medium is a product that needs heating or is prone to condensation, condensation may occur on the surface of radar antenna, which directly affects the measurement accuracy of radar level gauge. Necessary installation and treatment measures need to be considered; When the internal structure of the storage tank is complex, it is necessary to consider installing necessary conduits to reduce the measurement deviation; When the liquid level of the storage tank is low, there may be a blind spot for low liquid level measurement (or the measurement accuracy will be reduced);
