Capacitance Level Transmitter is used in sensing level of liquids. Capacitance Level Transmitter can be used for
conductive as well as nonconductive liquids. It is offered with PTFE sleeve for better insulation & to withstand high
temperature in conductive tanks the insulated probe acts as one electrode & the tank wall as another electrode, any
change in liquid level the dielectric value will change thereby changing the capacitance value proportional to the
liquid level. In case of nonconductive tanks, a reference probe is provided as ground electrode.
The output is 4-20mA, 4 wire connections for isolated supply & 3 wires for non isolated supply.
2 wire loop powered output is also available. The tank empty (4mA) & Full (20mA) calibration is
through easy field calibration button in case of 4 wire & 3 wire. For 2 wires it is through multi
turn trimpot. Rigid probe is offered for tank depth upto 3 mtr & Flexible probe upto 15mtr.

FILPRO make Magnetic Level Indicator provides clear, high clarity indication of liquid level. Typically, Magnetic Level Indicator consists
of three major components: Float Chamber, Float and Indicator System. Magnetic Level Indicator is principally designed as an alternative
to glass level gauges. We offer Magnetic Level Indicator having top-bottom, top and side mounted construction with two types of
indicatorsystemi.e.CapsuleandBi-colourRollers.Magneticlevelindicatorsaretailormadetovarioustypesofconstructionandsizes.
WorkingOfMagneticLevelIndicator
Magnetic Level Indicator operates on the principle of magnetic field coupling to provide fluid level information. Float chamber is
typically constructed with non-magnetic pipe having process connections that matches to the vessel connections. Float size and weight is
determined by the process fluid, pressure, temperature and the specific gravity of the
processfluid.Floatcontainsmagnetstoprovide360omagneticfluxfield.
Features
Roller Design : Indicator system consists of bi-colour rollers equipped with magnets
mounted on a rail inside the housing. As the level starts rising or falling, magnetic
float also travels with liquid level in non-magnetic chamber. The magnetic
interaction between magnets in float and bi-colour rollers causes each roller to
rotate 180°. For applications where High and Low Level electrical signals are
required,weofferadjustablelimitswitches.
Capsule Design : Indicator system consists of bi-colour capsule, which moves in
glass tube inside the housing. As the level Starts, rising or falling magnetic float also
travels with liquid level in non magnetic chamber. The magnetic interaction
between magnets in float and capsule causes capsule to travel along with magnetic
float. For applications where High and Low Level electrical signals are required, we
offeradjustablelimitswitchassemblies.
Performance
Reliable for aggressive, combustible, toxic, high pressure and high temperature (up
to150°C)liquidstoragetanks.
Side mounted magnetic level indicator most reliable and safe for hazardous
application like LPG, Oleume, Chlorosulphuric Acid, HNO2, and Solvents like
benzene,Toluenealcohols.

Webring forthefficientMagneticLevelSwitchforourvaluedclients.TheMagneticLevelSwitchconsists
of non-abrasive float carrying permanent magnet and non-ferrous stem carrying one. Two or multiple
reed switches. The float glides along the stem and when the float nears the vicinity of reed switch the
magnetic field of permanent magnet forces the contact to close, thereby completing the external
electricalcircuit.WeofferMagneticLevelSwitchatreasonableprice.

Horizontal Float Switch used to control liquid level in vessels containing corrosive or non corrosive liquids. It is used to control
pump,provideAlarm,forvalvecontrolorlevelindication.
Principle
The float lever carries a permanent magnet which is repelled by similar magnet mounted in the switch housing. The magnet
having the same pole directed towards each other are separated by a non magnetic diaphragm. The gland less construction offer

We offer Liquid Level Controller (Smart On) to automatically start & stop the pump with tank
level input from Magnetic Float Switch or Cable Float Switch. Liquid Level Controller (Smart On)
provides LED Indication for Power ON, Relay ON (Motor ON), Tank High & Tank Low. The
controller has provision to select pump mode as Pump UP or Pump Down. In Pump UP mode, the
pump starts at Low Level & Stops at High Level. Pump UP mode is used to fill the tank. In Pump
DOWN mode, the pump starts at High Level & Stops at Low Level. Pump DOWN mode is used to
emptythetank.
