GIC is the leading Averaging Pitot Tube Manufacturer in India providing reliable solutions for accurate pressure measurement to process industry worldwide.

Averaging Pitot tube is a multiport self-averaging flow meter. It is a primary element for flow measurement of gas, liquid, vapour in pipelines and ducts based on the principle of measurement of differential pressure created when an obstruction is placed in the fluid flow due to an increase in fluid velocity.

Averaging pitot tubes are generally used for large line sizes or ducts where other primary devices become relatively expensive.
Averaging Pitot tube comprises of following components:

* Outer impact tube – one piece construction

* Internal averaging tube

* Low-pressure chamber

* Head

The outer impact tube has a number of pressure-sensing holes facing upstream which are positioned at equal annular points in accordance with a log-linear distribution. The ‘total pressures’ developed at each upstream hole by the impact of the flowing medium are firstly averaged within the outer impact tube and then to a second order (and more accurately) averaged within the internal averaging tube. This pressure is represented at the head as the high-pressure component of the DP output. The low-pressure component is generated from a single sensing hole located on the downstream
side of the outer impact tube. A stable flow coefficient which is the result of a typical diamond shape, makes it a reliable flow-measuring primary flow element. Simple and inexpensive, long-term accuracy within acceptable limits over a wide range of flow, low permanent pressure loss & minimum operating cost make it an ideal choice for any design engineer. Retractable arrangements can be provided on request for online maintenance without stopping the flow.

GIC is the leading Aerofoil Manufacturer in India providing reliable solutions for accurate pressure measurement to process industry worldwide.

Aerofoil is primary flow element use to measure air flow in rectangular duct. An aerofoil is having the shape of the cross section of the aircraft wing, with the function of producing a controllable net aerodynamic force.

Aerofoil works on the principle of the relationship between flow velocity and the pressure fields in frictionless flow. Since the air particles follow the curved streamlines above the upper surface there must be a centripetal force across the streamlines which is accelerating the flow towards the centre of curvature. That force must be associated with a pressure gradient across the streamlines i.e. ambient atmospheric pressure at some distance from the surface grading to a lower pressure on the upper wing surface.

However, due to process temperature limits of the transmitter, this assembly cannot be used for process temperatures above 120 Degrees Centigrade.

The assembly consists of an orifice plate between two integral blocks having corner taps. Generally, a meter run pipe is recommended with an upstream length of 750mm and a downstream length of 250mm. The pipes are welded to the blocks with end flanges.

Routine tests:

a) PMI Test
b) Dye Penetration test
c) Hydro Test
d) Radiography Test
e) Calibration
f) NACE

Advantages:

• Use of an integral orifice flow meter will eliminate the measurement inaccuracies recorded in small orifice line installations.
• The Integral Orifice honed body reduces ID uncertainty
• By inserting precision bored upstream and downstream sections of pipe, the velocity profile distortion due to pipe roughness is reduced.
• The self-centering design of the Integral Orifice Plate eliminates plate misalignment.

Improves reliability and maintenance costs

• The integral orifice flow meter eliminates impulse lines, reducing leak points by over 50% and decrease start-up time due to the flexibility of numerous process connection options. The direct mount design minimizes line plugging by eliminating long lines, small-bore ports, and crevices while providing consistently reliable installations.
• Integral manifold head allows direct mounting of DP transmitters
• Ideal fluid types: liquid, gas, and steam below 120°C

GIC is the leading Restriction Orifice Manufacturer in India providing reliable solutions for accurate pressure measurement to process industry worldwide.

The restriction orifices are used for reducing fluid pressure and are designed somewhat differently from the orifice plates that are used for measuring flow rates. They are designed to slip between the piping flanges.

While single restriction orifices are often sufficient to meet the requirements, there are situations where limitations arise due to process conditions making the single restriction orifices unacceptable. In such situations, the use of multiple restrictions in series is a better solution.

The foremost consideration for the case of multiple restrictions is the pressure drop. This applies whether or not the fluid is liquid or vapor/gas. Higher pressure drop implies higher velocities resulting in vibration and noise problems.

The other consideration is not just about the maximum permitted pressure drop and this is particularly for gas flow. If the process condition indicates that critical flow will occur with the use of a single restriction plate, care should be exercised to avoid operating well beyond the critical pressure drop. Critical implies a pressure drop across the device exceeding 50 percent of the absolute upstream pressure at which point sonic velocity is reached. Construction of Multistage Orifice Assembly comprises multiple restriction orifice plates separated by a distance of one pipe diameter and welded with the pipes in between them. The end connection is either suitable for butt welding or with end flanges. IBR Form IIIC certificate can be provided as per requirement.

GIC is the leading Nickel Wire Mineral Insulated RTD Manufacturer in India providing reliable solutions for accurate temperature measurement to process industry worldwide.

In continuation with its endeavour to provide products of the best quality to clients, General has developed RTD with Nickel conductors in Mineral Insulated Construction for the first time in India. The basic difference between conventional and nickel conductors is the material of the conductor. In conventional, it is copper as against Nickel in newly developed MI.

Routine tests:

a) Accuracy/Calibration Test
b) Nitrogen Leakage Test (Weld
Closure Conformity)
c) Insulation Resistance Test
d) Thermal Response Time Test
e) Continuity Test
f) Dimension Checks

c) Self-heating error test
d) Hysteresis Test
e) Stability Test
f) Autoclave Test
g) Pull Test (Load Withstand Test)
h) Di-electric strength Test (H.V. Test)

Advantages:

• Most important advantage is that the RTD element is welded on to conductors and not brazed. As such same RTD can be used for much higher temperature of up to 600°C. In conventional RTD with copper conductor, brazing does not allow use of RTD above 450°C, after which brazing starts softening and RTD loses its contact with cable conductors. In Nickel conductors, as Nickel can be welded, contact is much more stronger even at a higher temperature.
• Nickel conductor cables are annealed at higher temperature than that of Copper. The cable therefore is much more softer. Hence RTDs made with nickel conductor are more pliable and easier to use.
• Nickel has much more strength than copper. Hence, they can be directly terminated in the terminal block avoiding another connection of flexible leads. RTDs with Nickel conductors give steady readings and chances of loose connection of flexible leads to copper wires is avoided.
• As Nickel conductors are welded to RTD element, it is a much more stable design than brazed RTD. This advantage is very important in applications where vibrations are present.
• Copper can get easily oxidised causing fluctuations in readings. Nickel being much more inert chemically, is not so prone to oxidation and hence gives stable readings over a longer period of time.
