To determine the intensity of the fluids, our Ultrasonic Flow Meters are an ideal solution. They are in huge demand in the market owing to their excellent performance. It works with clamp on transducers that provide accurate measurement of flowing liquid within an enclosed pipe. The Ultrasonic Transit-time Flowmeters work on the principle of measuring the time of flight difference between an ultrasonic pulse sent in the flow direction and an ultrasound pulse sent opposite the flow direction. This time difference is a measure for the average velocity of the fluid along the path of the ultrasound beam. By using the absolute transit time and the distance between the ultrasound transducers, the current speed of flow can be easily found. The Transit-Time based Flowmeters are tolerant of liquids with small amount of air bubbles or suspended solids.

U-Tube Manometers are versatile, economical instruments for the measurement of pressure, vacuums or differential pressures. Pressure measurements are accomplished by balancing a vertical head of indicating fluid with the pressure to be measured. As there are no cams, gears or levers to operate in the manometer, the readings obtained are always accurate.

The SS Turbine Flow Meter is widely demanded in the market due to the unmatched quality and unsurpassable performance.

Thermal Mass Flowmeters are suitable for all industrial and test rig applications that demand quick and precise gas measurement. It directly indicate the mass flow or normalized volume flow of gases without any additional pressure and temperature compensation. The flowmeters have an impressively high accuracy, short response time and a very wide flow range with virtually no loss of accuracy even at the lowest flow rates Thermal sensor consists of two sensing elements - a velocity sensor and a temperature sensor that automatically corrects for changes in gas Thermal Mass Flowmeters temperature(figure1). The transducer electronics heats the velocity sensor to a constant temperature differential above the gas temperature and measures the cooling effect of the gas flow. The electrical power required to maintain a constant temperature differential is directly proportional to the gas mass flow rate.

      Test Gauges are extremely sensitive and highly accurate with adjustable knife - edge pointer and mirror bands on the dial to assure precise readings and to climate parallax error. Also suitable for gaseous and liquid media, particularly for testing and calibration.   Application : Testing laboratories, instruments shops, gauge repairing & Calibration shops etc.

Strainers are specialized for removing solids from flowing liquids, Air, Steam or gases by means of a perforated or wire mesh straining element. The strainer improves the clearance in the medium, and prolongs the life of valves; protect expensive pumps, meters and other equipments. They are designed to remove pipeline debris, such as rust and pipe scale. Strainer are available in Angle “T” & 'Y' type , and are available in Cast Iron ,Cast Steel , MS Fabricated , Flange type, provided with filter element.

Type : Push or Pull type

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 prepared in such a manner as to compensate the level change in the well. Multi tube manometers with individual wells are used for multiple reading of pressure and also suitable for tank level gauging with purge tube. It is used for the precision measurement of pressure, vacuum, differential pressure for flow and liquid level measurement.

Range : From 0 to 10000 mmWc, VAC 0 to -760 mmHg

U-Tube Manometers are versatile, economical instruments for the measurement of pressure, vacuums or differential pressures. Pressure measurements are accomplished by balancing a vertical head of indicating fluid with the pressure to be measured. As there are no cams, gears or levers to operate in the manometer, the readings obtained are always accurate.

Operating Principle : Glass Tube Rotameter is basically a Variable Area Flow Meter. The differential pressure across the annulus area is constant and the flow rate is measured as a function of the annulus area. Glass Tube Rotameters consist of a tapered glass tube mounted vertically in a frame with the small diameter at the bottom and large end up. The tube contains a free moving float that rests on the stopper at the base of the tube. When the liquid flows, the float rises until its weight is balanced by the up thrust of the fluid and the float reaches a position of equilibrium. At this position it indicates the instantaneous rate of flow. The flow rate can be read from the adjacent scale..

YASH” make Plug valve is used primarily for on--off service and some throttling services. It controls flow by means of a cylindrical or tapered plug with a hole in the center that lines up with the flow path of the valve to permit flow. A quarter turn in either direction blocks the flow path. The Plug & Body seating surfaces, which are grinded and matched, are not exposed to the line fluid. Valves are impregnated with P.T.F.E. which provides greater wear resistance and ensures low consistent operating torque and at the same time reducing the need of lubrication P.T.F.E. Also enhances resistance to seizure.
