Series level transmitters are the extension
and development of pressure transmitter
technology. According to the principle that
the liquid with different specific gravity are
in linear relation to the pressure generating
at different height to realize the accurate
measurement and transmission of volume,
level height and weight of water, oil and
paste-state matters. They are widely used
in the industries such as power, petroleum,
chemical engineering, metallurgy, water
utilization, running water and food, etc.
