To have complete control of the utilities in the plant, it is very important to measure & monitor their consumptions. Steam being the one of the costly utilities in the process plant a proper measuring system must be in place. Unless & until we monitor, we cannot optimize its usage. We offer Vortex type flow meters for the steam measurement, Electromagnetic flow meters for the flow measurement of water, milk etc. Steam is energy medium, so measuring steam flow is actually measuring a flow of energy. In the same way that other energy flows are metered (e.g. gas, oil and electricity), measuring the steam flow to an entire factory allows trends in energy use to be established, making it easier to identify opportunities for cost and carbon savings Identifying areas where energy could be saved will enable companies to focus their efforts to reduce operating costs by using energy more efficiently. It helps to determine the direct efficiency of boiler. Vortex Flow Meter function on the Karman Vortex Shedding principle, which involves the generation of vortices in flow of fluids after impact on a bluff body placed in the flow path. The frequency of generation of these vortices is directly and linearly proportional to the velocity of flow Features of Vortex Flow Meter: Steam density changes with its pressure. The steam flow meters are provided with the density compensation to measure the steam flow accurately even at the fluctuating steam pressures. Very reliable PT1000 sensors are used to measure the temperature of the steam, from which the pressure & density is derived. Steam meters are constructed in complete SS body which ensures long life. Steam meters work with high turn down. Sensor used in the meter is capacitive type which is robust & highly reliable. It has no moving parts. Little resistance to flow.

A shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, etc. Volfram offers Shell and Tube Heat Exchangers with Smooth Tubes and Corrugated Tube through its fixed sized ranges and customized ranges of heat exchangers for applications such as pre -heaters, hot water generators, and condensers, re -boilers.

The immediate condensate discharge out of steam systems is absolutely necessary to retain the maximum possible capacity of the heat exchanger and to minimize the danger of corrosion, water-hammering & temperature fluctuations in the process. It is the task of Float controlled steam traps to discharge condensate out of steam consuming equipments but to keep the steam inside. Rotating Plug Steam Traps Working Principle VOLFRAM float controlled steam traps operate based on the rotary slide valve principle. These float controlled steam traps sense the density difference between vapor and condensate. As the incoming condensate reaches the trap body the condensate level rises so does the float. Due to the movement of the float the rotary valve is able to turn and open the outlet port and the condensate is discharged. Now as the level of condensate falls so does the float and the rotary valve turns and closes the outlet port. With this type of operation the condensate is discharged continuously. VOLFRAM float controlled steam traps operate effectively even at small differential pressures. Their operation is not affected by pressure fluctuations. These traps are provided with features such as air vent and a steam / gas barrier in the form of immersion tube. The thermostatic air vent offers the added benefit of significantly increasing condensate capacity on cold start-up. Features of Steam Trap: Only one moving point Proportional control action Exact, impact free & silent condensate discharge Independent of pressure & temperature Extremely long working life Little wear with extremely low maintenance Simple mechanism Applications: Float traps are recommended to be installed at process equipments.
