Rosemount 5900S Series
2-12
The Rosemount 5900S with LPG/LNG Antenna is
designed for level measurements in LPG and LNG
tanks. A 4 inch still-pipe is used as a wave guide for
the measurement and prevents a turbulent surface
from disturbing the measurement. Radar signals are
transmitted inside the pipe towards the surface.
The pressure sealing is a quarts window approved
for use in pressure vessels. As standard the gauge is
also equipped with a fire-proof block valve and a
vapor space pressure sensor.
The Rosemount 5900S with LPG/LNG Antenna is
available in two versions for 150 PSI and 300 PSI.
The Verification Pin allows you to verify
measurements without opening the tank by
comparing the measured distance with the actual
distance to the Verification Pin.
