Our range of magnetic level indicators is designed and developed to offer high clarity indication of liquid level. The indicator has a float-containing magnet that rise and fall with the liquid. As it moves, the information is transferred to the indication rail mounted outside the tube. The white and red indication flaps symbolize air and liquid level respectively. The liquid level is also indicated by follower - Magnet type indicator.

These magnetic level indicators can be mounted in various orientations, such as by the side of the vessel and top of the vessel or if necessary at the bottom. These magnetic level indicators are used for high pressure, high temperature, coloured and corrosive liquids.

Our gamut of highly accurate remote level indicators helps to keep an eye on the dislocation of the water levels in the boiler. When the water level in the boiler increases, the rising water column presses the red indicating liquid (sealing liquid) from the first phase to the second phase and then it gives an indication in the Inspection glass of the indicator. When the water level in the drum falls, the indicating liquid in phase three in the inspection glass also falls. When the water level in phase three is continually filled up, the water vapour formation in the condenser takes place.

Product Description:Reflex Gauges: 
These are assembled with flat glasses with inner surfaces of reflecting prisms. Due to total internal reflection liquid level shows black in contrast to a mirror-like surface above, The gauges are used for services where observation is required at a distance and on low-pressure boilers. 
Transparent Gauges: These are assembled with two numbers of totally transparent toughened glasses to give a through the vision of liquid levels. These gauges are recommended for interface levels, coloured fluids where colour is of interest to the process behaviour and services where excessive foaming may exist. In high pressure, boilersthese gauges are recommended to be used with mica shields. 
Glass: Teleflo engineers continuous research, development and experimental studies on glass toughening and composition has made the tempered glasses used in these gauges most dependable providing a high strength resistant to both thermal and mechanical shocks and with the highest degree of visibility.

We have designed level gauges and valves with utmost care for getting the maximum economy. Your level gauge should have the same strength as your vessel to withstand the high pressures to which it is subjected and the corrosive characteristics of the fluid. Also, your valuable process fluid should never leak out through the glass fitting.

In industries, you may have to measure the levels of colourless liquids, an interface of immiscible fluids, liquids with sub-zero temperatures and liquids with too much foaming. All these requirements can be met with by our latest types of flat glass level gauges.

The heavy duty tubular level gauges we offer comes with heavy wall glass tubes with 3 mm thick machine made channel protector. These are designed to tolerate extreme conditions and offer very high durability. These are also offered in side mounted heavy duty indicators and top mounted level indicators. The side mounted heavy duty indicators are developed keeping in mind the extreme conditions it could face.

These are fabricated using strong materials and provide extreme durability. These indicators come with built-in glands and can be provided with valves if required. The top mounted level indicators provide high levels of safety to the storage tanks.

As they are mounted at the top of the tank, it cuts down the risk of hazardous fluids getting splattered through any leakage. There is a float that is streamlined by a perforated pipe and a sealed glass tube. Float steam tip has an inbuilt pointer used to indicate the level correctly.

Our array of Rota meters is available in panel mounted types and pipe line mounted types. The pipeline mounted instruments are designed to ensure pipeline installation stress, strain and vibrations. The unique gland arrangement offers zero leakage and long life to the metering tube.


We offer Rota meters in various types such as:

Our range of manometers is extensively used in various industrial applications for pressure and vacuum measurements. These are also used for flow measurement techniques. The manometers we offer are available in wall-mounting or pedestal type and 'U' tube or single limb type. They can either be of an inclined type or can be provided with a vernier scale for obtaining greater accuracy. The normal accurateness of the manometer is 1 mm but with an inclined tube of 0.1 mm, better accuracy can be obtained. A changeable vernier can provide a readability of 0.1 mm.

Types of manometers:

Single Limb Manometers-These single limb manometers are provided with a well which has a much larger area to that of the manometer tube and the level variation in the well is negligible to the rise in level in the Manometer tube. The scales of these manometers are also equipped in such a way as to compensate the level change in the well. Multi tube manometers with individual wells find application for multiple reading of pressure and also appropriate for tank level gauging with purge tube.

'U' Tube Manometer-The standard 'U' tube type manometers we offer consist of two straight glass tubes with a 'U' bend at the bottom end. Our range of manometers is provided with top and bottom blocks that are fitted with accessories such as external zero adjuster valve, safety cover, filling and drain plugs, catch pots, zero leak ball check valves, zero adjustable scales, vernier scale, levelling screws, swivelling body and others.
Connection: 1/8" / ¼" / ½"; BSP, NPT, Ferrule or hose connector. 
To prevent the fluid from leaving the manometer check valves are used if the instrument is operated beyond the range. Return wells are also used to prevent loss of the representative fluid by collecting the over flow fluid and returning it to the manometer.

Sensitron Thermocouples and wells are designed for making available to the industry a complete range of thermocouples for measuring temperatures from 150°C to 1600°C and, are highly accurate and sensitive. These thermocouples are offered with a very wide range of thermowell's of different materials to suit the application. Basically, a thermocouple is composed of two dissimilar metal wires butt welded together in a circuit.

The circuit develops a small EMF, in accordance with See back effect, between the measuring and reference junctions. This EMF can be measured by means of any pyrometer in terms of temperature. Sensitron Thermocouples are fabricated by gas or arc welding or resistance welding in accordance with ISA recommendations.

Special Thermocouple- The assembly consists of single or duplex thermocouple elements with cylindrical ceramic insulators encased in a spring loaded the stainless tube.

It is supplied with a screwed cover head and pipe nipple with 4 ¼' NPT mounting thread. In order to get the highest speed of response to a temperature change, the last inch of the bore in the well is reduced in diameter to provide a tight fit around the sensitive tip of the thermocouple. The spring loaded feature ensures positive metal to metal contact between the thermocouple and well allowing the highest possible rate of heat transfer to the measuring junction. Spring pading also allows movements of the thermal element due to expansion and contraction without damage to the element or connecting head and terminal block.

Our side mounted indicators are designed keeping in mind the extreme conditions they would have to face. They are manufactured using very strong materials and hence also provide prolonged durability. These indicators have built-in glands and we can also provide valves if required.
