Outstanding Features
Introduction
Float operated liquid level transmitter, indicator and controller, comprises of a level transducer and a signal converter and is used for continuous level indication and control of any liquid, chemically compatible with the transducer material, unaffected by electrical conductivity, temperature, pressure or viscosity. The Floats are designed for variety of liquids and its unique self-cleaning construction is well suited for even sticky or dirty environments, reliability and accuracy-this is an ideal transmitter. Operating PrincipleThe Unit operates on the principle of buoyancy. During the rise and fall of liquid level, the Float moves and the magnetic field change and actuate the chain which develops a proportional voltage. The sensed voltage is fed to a transmitter for converting it to a signal of 0-5 V Dc or 4 � 20 mA. The transmitter can also be incorporated with a digital display or step less adjustable multiple alarm relays (featuring high level alarm, low level alarm, or both & low level pump (or solenoid valve) on & high level off and vice-versa. ConstructionThe transducer consists of a float and guide tube assembly in nonmagnetic material to achieve undisturbed flux. The float can be in nylon, PP or SS. No gasket or seals are used and there is only one moving part, the float assuring long trouble free life. Being entirely glandless, there is no possibility of fluid leakage into the transducer. Installation and Wiring : The transducer is mounted internally and externally through a chamber by means of a flange connection. External mounting is adopted to overcome limited space within the tank or where mechanical devices operate or where isolation tank is required for regular servicing. The Transducer is recalibrated in the factory and comes to you ready for installations. For operation of level transducer, it has to work in conjunction, with a signal converter which have line or loop powered electronics. Line powered transmitter can be incorporated with a digital display and / or adjustable multiple alarm relays. Loop powered transmitter is employed for remote signaling to a process indicator / controller.

Malhotra Bros & Co. is a well-known Magnetic Level Switch Manufacturer and Supplier in Delhi. The Magnetic Level Switch goes through several quality-checks, which ensure its top-notch quality. The Magnetic Level Switch is an economical, maintenance free and reliable device used for high, low or intermediate point level switching. The Magnetic Level Switch is for tanks with inaccessible tops or bottoms and where insertion depths of top mounted models are exceeded. Construction & OperationCompact and rugged construction, consisting of a free moving float assembly and a switch enclosure in non-magnetic material to achieve undisturbed magnetic flux. It employs dual magnets- one carried out by the float arm and the other by the contacts carriers, housed in the switch enclosure. A change in the liquid level brings the like poles of the dual magnets opposite to each other, and resulting repulsion force ensures a change-over of contacts, of the switch housing. These Magnetic Level Switches come in various non-magnetic materials and construction styles to suit board range of medias/applications. It is designed to provide high repeatability and to minimize effects of shock, vibration & pressure.

We are known as a trusted Magnetic Liquid Level Indicator Manufacturer and Supplier in Delhi, offering a well-tested range. The Magnetic Liquid Level Indicator is made from quality components, which make it more durable and reliable. The Magnetic Liquid Level Indicator is known for its smooth and accurate operation. Our Magnetic Liquid Level Indicator comes at competitive prices. IntroductionLevel Indicators are laterally to be flanged to the tank as a communicating pressure resistant vessel and serve for level measurement and supervision of liquids and liquefied gases in open and closed tanks. These can be used when instruments with high resistance to pressure and temperature are required or if sight glasses or similar indication parts for reasons of security cannot be used. This measuring system is preferred because there is a safe pressure and gastight separation between measuring and indication part. Therefore, the instruments are suitable for a wide range of applications for the chemicals and Pharmaceutical industries for the petrochemical industry, refineries, oil and fuel tanks, storage tanks, etc. In a communicating float cage which can be flanged to a tank is a cylindrical Float of stainless steel or plastic. A permanent magnet forms part of the float. Outside the liquid on the dry side a Magnetic Level Indication is fitted to the float cage.

We are among the leading Manufacturers and Suppliers of Tube Type Liquid Level Controller. The Tube Type Liquid Level Controller is made from quality components, ensuring the delivery of excellent performance for years and years. The Tube Type Liquid Level Controller comes at market leading price. IntroductionMagnetic float and tube type, level switch in conjunction with control unit is an established and reliable technique in industry for point liquid level sensing and control in open or pressurized vessels. It offers trouble free service in conductive/non-conductive liquids under widely varying temperatures, pressure, liquid viscosities and corrosive conditions. Besides, it provides high repeatability and effect of shocks/vibrations is minimal. Construction & OperationSimple and sturdy construction, consisting of a float and guide tube, made of nonmagnetic material to achieve an undisturbed magnetic flux. The float has a magnetic system within it and moves freely along the guide tube, which contains glass encapsulated hermetically sealed switches, located at preset positions. Reliability of float movement is achieved through suitable clearance between it and the tube. Float follows the liquid level and magnetically actuates the contacts to give an electrical signal, which in turn can operate remote alarm or a relay to control auxiliary devices like solenoid/motorized valve or pump motor starters. Single/multiple switching is possible through a single float, however to suit specific applications, multiple floats can be employed. The Tube Type Liquid Level Controller is available in various materials and construction styles to suit wide variety of medias/applications. InstallationsMounted internally or externally through a chamber. External mounting adopted to overcome limited space within the tank or where mechanical devices like stirrers operate or where isolation tank is required for regular servicing. It can be installed vertically from top to bottom. Side installation is also possible with slight modification. Control UnitContains electronics and comes separate as an accessory to the sensor. To allow low power switches to control high amperage or voltage devices. Or To convert non-latching switch outputs into latching alarm outputs. The relay provided in the Controller is of 5 Amp. Capacity. On no account must a switch be used for the direct starting of burners, heaters, motor pumps, alarm, it is essential that the contacts are wired in series with the relay coil (N/V coil) in a contactor starter.
