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.
