FLOWT OPERATED LEVEL

'CRISTAL' Float-operated level Transmiter is used for
contInuous level Indication and Control of any liquid.
This consists of a level transducer and a signal converter.
This can be used for any liquid chemically compatible
with transducer material, unaffected by electrical conductivity.
temperaturc, pressure or viscosity.
The transducer consists of a float and guide tube assembly
in non-magnetic material to achievc undisturbed flux.
A chain of closely spaced glass encapsulated reed switches
and electric resistors are placed inside guide tube. According
to level rise and fall, the float moves and actuates the
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 a transmitter for converting
it to a signal of 0 - 20 m.-\ or -1 - 20 mA. The transmitter
can be incorporated with a dibrital display and or / adjustable
multirle alann rdays.
The transducer can be mounted internally or externally
through a chamber by flanged connection of y' 0:8 or 4"
!\iB. The tran<:ducer is pre-calibrated in the fa~:ory.
To operate the level tTansducer, it has to \\ork in conjunction
with a signal converter, which could have !lI1e or 100IJ
powered electronics. L!!'1f..' r'('\,.'errd transmitter
can be incorporating with a digital display. Loop powered
transmitter is used for rcn:otc signaling to a process
indicator/controller.
ll1e outstanding features of this transmitter arc, it
is pre-calibrated at factory, 4 - 20 rnA processed output
signal, 2 or 4 wire units, liquid level or liquid/liquid
interface detection: high accuracy and repeatability and
adjustable multiple alann relays.
The level transmitter can be supplied to any range up
to 4 Mts. With flanged connection. Material of construction
will be nonnally SS-316 & suitable for max. temp of
1500 C. and pressure 15 Kg//cm2.
Enclosure protection will be weather-proof or flame proof.
Spiral converter will have normal output 4-20mA
(OptioNED 0-20 o 0I - 0 - 5 VDC) max. load -100 ohms.
supply voltage of 24 V DC / 110 or 220 V AC. Digitai display
(optional) of 3 1/2 / 4 1/2 digits in 0% or in cms. Control
(optional) of multiple. stepless adjustable: OF relays
rated for 6A at 240 V AC.Mounting can be panel or wall
and enclosure protection of weather proof.
