Features of Magnetic Float Operated Guided Level Transmitter
It is used for continuous level indication and control for any liquid that is chemically
compatible with its wetted parts. It has an accuracy upto 0.5% FSD and can be used upto
90 deg C temp. & 20 kg/cm2 pressure. The maximum length that can be supplied is 3
meters. It is available in different material of construction like SS304, SS316, PVC and
PP & with different Float sizes. The enclosure is IP56/IP65/Ex-proof Gr IIA & IIB
approved to suit various service condition & application. It is factory calibrated and
requires no calibration at site. It is simple to install and is supplied with 3" NB ASA
150# Flange.Features.
Applications: Tanks of Oils, fuels, chemicals, Pure/Industrial water, ship/LPG tanks,
critical Inventory, Pharmaceutical plants etc.
Construction & Operations
It comprises of a level transducer and a transmitter. The transducer consists of a float
& guide tube assembly in non-magnetic material to achieve undisturbed flux. A chain of
closely spaced glass encapsulated reed switches & a resistor is placed inside the tube.
During rise and fall of liquid level, the float moves & actuates a reed switch in the
chain, through a magnet system within it and develops a proportional voltage. The
operation is similar to a sliding resistance potentiometer. The sensed voltage is fed to
the transmitter for conversion to a signal of 4-20 mA, which can be either processed
through a display unit to give a digital indication, with or without alarm set points or
employed for use with Process Indicator, PLC/DCS or Recorders.
