Salient Features
Construction & WorkingIt consists of a float & guide tube assembly in
non-magnetic material, to achieve undisturbed
flux. A chain of closely spaced glass
encapsulated reed switches and resistors are
placed inside the guide tube fig.1. During rise
and fall of liquid level, the magnetic float moves
and actuates a reed switch and develops a
proportional voltage. The sensed voltage is fed
to the transmitter located in the enclosure for
conversion to a signal of 4-20 mA, to use with
PLC or DCS. Alternatively, the signal can be
transmitted to a display unit for remote indication
or to a display unit integral with transmitter for
local indication.
Magnetic Float Operated, Guided Level Transmitter
“FGT”It is a reliable technique for continuous level indication and control of liquid, chemically compatible with the transmitter MOC. The float is designed for variety of liquids and its unique self-cleaning construction is well suited for even sticky or dirty liquids with no float hang-ups.
DT = Top Dead Band, DB = Bottom Dead Band GTL= Guide Tube Length
DT & DB vary according to liquid SG

Internal Installation
External Installation
1. Internal Installation
Transmitter is top mounted on the tank. A stillwell with perforation is recommended for liquids under turbulence. For fitment of stillwell, ensure that NB of tank nozzle is greater than the diameter of stillwell.
2. External Installation
Transmitter is top mounted on a chamber, external to the tank. This installation is adopted on the tank, containing mechanical devices like stirrers, ladders & other internals or to overcome space limitation in the tank.
