Pressure Gauges intended for process industries such as chemicals, petro- chemicals, energy or gas industry, food processing, nuclear, etc
These pressure gauges have been designed to satisfy requirement to operate in aggressive environment

Applicable for all Models, where code “E” is specified in Option column

Features

Generally Pressure Gauges Differential pressure are provided with micrometer type pointer, by which zero can be adjusted after opening the Bezel & Glass. However for Gauges with Liquid (Glycerine / Silicone Oil) filled case, this arrangement is practically not suitable, since the filling liquid has to be drained before opening the Bezel & Glass. After doing the zero adjustment, the Bezel & Glass has to be re-assembled and again the case has to be filled with liquid.

In order to overcome this difficulty, General instruments consortium has developed a unique of external zero adjustment. By this arrangement, zero can be adjusted without draining the Glycerine, without opening the Bezel, without removing the Glass & without touching the pointer, just by rotating a knob provided out side the Gauges. This arrangement is highly recommended from the maintenance view, especially for liquid filled Gauges.

Features

One of the most economical solutions to protect the thermowells from chemically agressive fluids is to provide a bar-stock flanged thermowell made out of conventional stainless steel (SS316) with loose lining in the form of a sleeve on the entire wetted portion. This will provide strength from stainless steel & corrosion resistance from the lining.

Material Selection Guide

Features

For high pressure applications and where welding is to be avoided, Van Stone design thermowells are used. These are machined from a single barstock, sandwiched between the nozzle flange and cover (companion) flange. The OD of the machined portion corresponding the raised face portion of the flange. Wake frequency calculations (in accordance with PTC 19.3) are performed where ever data is made available and are essential in order to suggest appropriate dimensions of thermowell.

Features

General Instruments orifice plate is a device used for measuring flow rate. Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the it. It uses the same principle, namely Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the velocity increases, the pressure decreases and vice versa.

Features

The weldneck flange assembly is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. The pressure tappings are provided through the flange which are at a distance of 25.4mm (1") from the relevant face of the plate. Weldneck flanges are prefered since the joint between flange and pipe can be subjected to radiography, to ensure quality of welding joint.

The slip on flange has a low hub because the pipe slips into the flange prior to the welding. It is welded both from inside and out to provide sufficient strength and prevent leakage. The slip on flanges are bored slightly larger than the OD of the matching flange. SORF flanges are not preferred where pressure tapping through flange is required, since after welding in line blocks the tapping holes which need to be redrilled at site after welding in line.

Orifice assembly with carrier raing and flange union is provided to facilitate pressure tapping, by means of corner tappings. This construction is generally used for lower sizes (less than 2"). However carrier rings can be used for higher line sizes also.

Features

The restriction orifices are used for reducing fluid pressure and are designed somewhat different 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, use of multiple restriction in series is a better solution.

The foremost consideration for the case of multiple restriction 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 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 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 of multiple restriction orifice plates separated by a distance of one pipe diameter and welded with the pipes in between them. End connection is either suitable for butt welding or with end flanges. IBR Form IIIC certificate can be provided as per requirement.

Features

General Instruments Manufactured Integral Orifice Assemblies are another type of measuring flow device, which caters to the principle of maintaining constant reynolds number through out the process of media entering and processed and finally out of the assembly. This is possible with the precision manufactured device wherein the input flange, with pipe chamber, the orifice assembly and the outlet pipe chamber and the subsequent flange for the flange end connection, all shall be attributed to constant reynolds number.

Features

Most flow meter technologies require significant and often unattainable upstream and downstream straight-run to meet and sustain specified accuracy. Similarly, most pump and compressor manufacturers recommend significant straight-run to ensure even flow into the pump to minimize wear and maximize service life.

General flow straighteners / conditioners reduce straight-run requirements to just a few diameters. General flow straighteners / conditioners eliminate the flow distortion effects of elbows, pipe expansion or reductions, valves, dampeners and other disrupters to produce a swirl-free, symmetrical and repeatable flow profile to the flow meter, pump or other critical components.

Further, General flow conditioners have extremely low pressure drop, resulting in significant energy cost savings over alternative flow conditioning technologies.

General flow Straighteners / conditioners are available in straight-pipe runs, a unique 90° elbow and insertion panel designs for virtually any pipe, tube or duct size.

General flow conditioners and straighteners enhance accuracy for many flowmeter technologies

Flowmeters require a swirl-free repeatable and symmetric velocity profile to operate within stated accuracy specifications. Flow disturbances caused by ball valves, elbows, headers, and blowers for example may adversely affect a flowmeters accuracy.

There are two ways to mitigate flow disturbances.
1. Maintain sufficient straight run upstream of the meter.
2. Utilize General Elbow flow conditioners / straightner.

General flow conditioner's technology is ideally suited to work in various medias including gas, stream, liquids, slurries, sludges, hydrocarbons, and more. The General flow conditioner outperforms all other flow conditioning technologies with respect to minimal pressure loss, non-fouling design, and repeatable flow profiles. The following highlights summarize the advantages of using this technology with various flow metering.

Features

General Flow Nozzle is used in typically high-velocity, non- viscous, erosive flow. They are suitable for determining the flow rates of fluids at high temperature and high pressure.

General Flow Nozzles are erosion-resistant, consistently accurate and vir tually maintenance-free. They per form a wide variety of applications that include air, water, steam, gas, chemical substances and high temperature applications. The rounded design provides a more effective sweep-through of par ticles in the flow stream, which extends product life by reducing wear and potential damage. Flow Nozzles are manufactured in strict accordance with ASME MFC-3M, BS-1042 and ISO-5167 standards. For critical measurement applications, wet calibration at reputed flow laboratories can be offered. Also we have an IBR approval for our manufacturing unit hence we can provide IBR form IIIC cer tificate for flow nozzles. Flow Nozzles have a smooth elliptical inlet leading to a throat section with a sharp outlet. Restriction in the fluid flow causes a pressure drop, which relates to the flow rate by applying Bernoulli’s equation.The smooth inlet of the flow nozzle results in a higher coefficient of discharge than most other differential meters. This higher efficiency means greater flow capacity when compared to most other differential meters of the same size.

 

There are three types of Flow Nozzles

ISA 1932, with corner taps
ASME long radius, low beta ratio (0.20 < b < 0.5), with throat tap
ASME long radius, high beta ratio (0.25 < b < 0.8), with radius taps (D & D/2)

 

ASME long radius, low beta ratio Nozzle with throat taps is used in
steam turbine per formance test as per ASME PTC-6 code.

ISA-1932 nozzle can be mounted with carrier ring or in between

flanges with corner taps.

Long radius nozzle are normally with weld-in branch pipe with
radius taps.

To avoid welding of dissimilar metals, nozzles are also installed in the
pipe with holding ring.

Features

The orifice assembly or the flow control element, valve, is calibrated under fluid mechanics standards of ISO 5167 and IEC 60534 standards. The process and the procedure of the measuring flow calibration of the device and the design is as per the international standards applicable for volumetric and gravimetric conditions.

The flow calibration bench for upto 12” size, is applicable for pressure 2 rating upto 3 kg /cm g and for all ambient conditions. The testing media is water. The calibration unit is under free length or straight length as per the ISO standards for mounting in such conditions applicable for orifice assemblies with water as media and with calculated beta value to decide the free length for calibration of sensors. For valves, the condition is kept at ambient conditions with water and based on IEC 60534 standard the flow coefficient value of the valve is matched with desired flow rate applicable under differential pressure conditions, under applicable and available free or straight lengths.

The bench gets the water from an underground tank with an overall capacity of  m3 which is having a magnetic level gauge mounted to check the level of water. The level in turn helps to clear the pressure applicable under the centrifugal pump which is mounted to the side to generate the desired and the requisite pressure for the flow assembly, either valve or orifice.

The differential pressure in the assembly is created by either manually adjusting the input pressure, with adjustable valves at the input line to  the device for calibration or by pneumatically adjusting the variations through control pneumatic actuators adjusting to set points.

Isolation valve for primary take offs, where the valve is directly mounted to the vessel or process pipe. Instruments may be directly mounted to the valve outlet or alternatively remotely mounted with gauge line / impulse pipe work.

GBV

Features

A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole or port,through the middle so that when the port is in line with both ends of the valve, flow willoccur. When the valve is closed the hole is perpendicular to the ends of the valve, and flow is blocked. The handle will be inline with the port position letting you “see” the valve position.

Ball valves are durable and usually work to achieve perfect shutoff even after years of disuse They are therefore an excellent choice for shutoff applications. They do not offer the fine control that may be necessary in throttling applications.

Features

Compression Tube Fittings:

General compression tube fittings are Double Ferrule type fittings which provide leak proof torque free seals at the tubing connection. They provide safety and eliminates hazardous leaks of fluids in instrumentation field for process, pressure, hydraulic & other applicable tubing system.

The basic general tube fitting is a 4 piece fitting consisting of the nut, the back ferrule, front ferrule and the body. When installed, it becomes 5 piece connection with the addition of the tubing providing solid leak free joint.

The tube ferrule grasp tightly with no damage to the tube wall. The success of the ferrule lies in the combination of geometry & metallurgy. All the action in the fitting is by an axial movement along the tube instead of rotary motion to form a joint. This axial movements prevents any torque to be transmitted from a fitting to tubing, the making of the joint strengthens the tube futher.

Another advantage of the General Fittings is that the sequential action of the twin ferrule overcomes variations in the wall thickness, hardness and dimensional tolerance of the tubes. This way proper ferrule interaction compensates for most of the variables which lead to failure in fittings.

General Fittings are easy to install and require no special tools in the process. They are reusable several times and can withstand heavy impulse and vibration both in vacuum and pressure systems. Absence of damage to the tube surface prevents fatigue failure.

General Double Ferrule compression tube fittings have the following features:
