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 colorless liquids, interface of immisible 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.
These gauges are constructed with a solid forged steel bar main chamber and cover plates recessed to have perfect alignment of gaskets and glass. Though rated for 2000 psig. these are light weight and hence do not need any combursome supports for medium lengths. With special main chamber construction these gauges can be supplied upto 3000 psig. Main Chambers are available in C.S, M.S, SS304, SS316, P.P., P.V.C., FRP and Rubber lined. Gaskets are of CAF, GRAFOIL, TEFLON, NON-ASVESTOS, etc.
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.
These are assembled with two numbers of totally transparent toughened glasses to give a through 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 boilers these gauges are recommended to be used with mica shields.
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.
Our range of liquid level indicators are designed to provide high clarity indication of liquid level. The float-containing magnet in the indicator rises and falls with the liquid. As the float moves, this information is transferred to the indication rail mounted on the outside of the tube. The white and red indication flaps represent air and liquid level respectively. Liquid level is also indicated by follower - Magnet type indicator.
These magnetic level indicators, liquid level indicators can be mounted in various orientations, such as onto the side of the vessel and top of the vessel or if required on the bottom. Our range of Magnetic level indicators are used for high pressure, high temperature, colored and corrosive liquids.
Our highly efficient remote water-level indicator, liquid level indicators detects the water-level fluctuations in the boiler drum. These liquid level indicators are very delicately designed to provide flawless indication's.Remote Level Indicators
Our highly accurate remote level indicators help to keep a track on the displacement of the water levels in the boiler. When the water levels in the boiler rises, the increasing water column presses the red indicating liquid (sealing liquid) from the first phase into second phase and then indicates in the Inspection glass of the indicator. The water displaced from Phase one flows from the condenser into Phase three and then into the boiler. If the water level in the drum falls, then the indicating liquid in phase three in the inspection glass, falls correspondingly. The water vapor formation in the condenser takes place when the water level in phase three is constantly filled up.

(Glass Tube Type for General Industrial Service) : These glass tube variable area rotameters are designed to provide visual indication of flow of wide range of transparent to semi-transparent liquids and gases. They are of robust construction with dowelled side plates, interchangeable glass metering tubes and floats and wide-view windows at front and rear. Flow range can be readily changed by detachable scales.
By-pass rotameters are suitable for economical measurement of flow in larger pipelines generally 2" NB to 14" NB. The construction is simple and reliable consisting of orifice plate with carrier ring and a shunt rotameter. The flow rate through the rotameter is proportional to the pressure drop across the orifice plate created by the main flow and is calibrated accordingly. During installation care should be taken to ensure laminar flow in the pipe section. Orifice plate dimensions are based on ISA/ ISO/BS standards.

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 thermowells 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.
The assembly consists of single or duplex thermocouple elements with cylindrical ceramic insulators encased in a spring loaded stainless tube. It is supplied with a screwed cover head and pipe nipple with 4 ¼' NPT mounting thread. In order to get 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.
