Turbine Meters have a spinning rotor with propeller-like blades mounted on bearings in a housing. The rotor spins as water or other fluid passes over it. The flowrate is proportional to the rotational speed of the rotor. They are used to detect the rotor speed, including mechanical shafts and electronic sensors. They infer the volume by measuring the rotation speed of a turbine suspended in the flow stream. They differ according to the design of the spinning rotor. This can be used on both liquids and gases. They are sensitive to viscosity and low-viscosity fluids

Ultrasonic Flow meters are usually noninvasive and can be used on many flows that would damage other meters. They use an electronic transducer to send a beam of ultrasonic sound waves through the water to another transducer on the opposite side of the unit. These are available in two forms, which include Doppler and transit-time. With the Doppler meters, an ultrasonic pulse is beamed into the pipe and reflected by inclusions. This type of meter is frequently used as "clarop on″ device which can be fitted to existing pipelines. There are two types of ultrasonic transducers, first one usually uses pulse transmission and is for cleaning liquids and second is for continuous wave transmission and is for dirty liquids.

Vaporizing Pot Burner is an uncontrolled space heater. These burners are used as a room space heater, water heaters and central heating systems. A light distillate fuel oil intended for use in vaporizing pot burners. It vaporizes the oil before ignition. In a vaporizing pot burner only the heater vaporized fuel is combusted. In the air-atomizing burner the fuel is atomized and then burned, resulting is less residue of unburned material than the vaporized pot burner.

Vortex shedding flowmeters consist of three basic elements comprising of vortex generating element, sensor and an electronic module. They result in pressure and velocity changes around and downstream of the vortex generating element. The frequency of this shedding flow meter is directly proportional to the volumetric flow rate. These are available in pipe sizes ranging from 15mm to 300 mm. This has high accuracy and rangeability.

Wall deslagger soot blowers are suitable for wall cleaning application such as furnace walls, generating tube banks or divisional wall tubes of any coal fired boiler. The cleaning action is achieved by projecting the lance tube with nozzles through a short distance into the boiler and rotating the nozzles by a set of degree of rotation with the blowing medium flowing through it. It is available as manual and motorized soot blowers.

Waste heat boilers are versatile steam/hot water boilers. It is designed for operation in conjunction with a wide range of heat generating equipment, such as gas turbines, reciprocating engines, incinerators, gasefiers and other process heat plant. As well as unfired boilers, the waste heat range features composite boilers, which incorporate additional firing to give better flexibility and security of steam or water supply. A wide range of control and auxiliary plant solution are available to support the range.

Water Wall Tube is used to line the boiler along its other skin. Water wall tubes are steam producing tubes because of the radiant exposure to combustion.

Wet back fire tube boiler design has a water cooled turn around chamber, which is used to direct the flue gases from the furnace to the tube banks. It requires less refractory maintenance. However, internal pressure maintenance, such as, cleaning is more difficult. In addition, the wet back design is more prone to water side sludge buildup, because of the restricted flow areas near to the turn around chamber. This boiler is a cylindrical vessel, with the flame in the furnace and the combustion gases inside the tubes. The furnace and tubes are with in a vessel, which contains the water and steam. It ranges from 15 to 1500 horse power. These boilers are designed for 500 HP at maximum allowable working pressure of 150 psi.
