Ordinary glass tube level meter connects to  with up and down valves ,and can easily read the height of medium level in the container.Bi-colored glass tube level meter uses natural lights to show the level height.Steel ball in the up and down valves to stop medium flowing under the work pressure≥0.3Mpa.Widely used in industry to show level height .

Technical parameter:

Survey scope: 500、800、1000、1100、1200、1400、1700mm

Pressure: ≤1.6Mpa

Temperature: ≤200℃

steam pressure: ≤0.6Mpa

steam connect: M12×1(outside)

principle:

           Flanges are arranged on up down valves to connect with the measured container.steel balls are used in up and down valves to stop liquid flowing quickly.in ordet to close automatically ,the pressure inside and outside of the container should not be under 0.3Mpa.
