Flow & Level Instruments

Product Details:

An 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 orifice plate. It is based on 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.
It is also used for reducing pressure or for restricting flow. It is often called a restriction plate.

External Chambers are used for mounting the other range of process level instruments to a vessel.Externally mounting an instrument in a chamber means it can be isolated for routine maintenance while keeping the plant operational. It is also useful for in-tank restrictions that do not allow mounting of the instrument in a vessel

• Optimized for use with Guided Wave Radar, Hydrostatic, Float based and Magnetostrictive Level Transmitters, Displacer Level Switches and Transmitters, Vertical Float Level Switches, Horizontal Float Level Switches
• Switches and transmitters might not give accurate results in turbulent process conditions. Hence, they are inserted in a Stilling Well mounted inside the tank which helps in calming the process liquid, creating favorable conditions for switches & transmitters to work accurately

Electromagnetic flow measurement is based on Faraday's Law of Induction. The law states that voltage is induced across a conductor moving through a magnetic field. The functional principle of electromagnetic measuring devices is also based on this law of nature. An emf is generated across a conductor moving in a magnetic field. This emf is directly proportional to the flux density, velocity of conductor and length of the conductor. This principle is used for flow measurement through electromagnetic flow meter. The flowing liquid itself is a conductor and its average velocity is the velocity of conductor.

E = BYV.D.
Where
E = Induced emf proportional to velocity.
B = Magnetic flux Density
V = Average velocity of the media
D = Distance between two electrodes or Practically the diameter of the flow sensor

Since the Flux Density and diameter of the flow sensor are fixed for given combination Theemf becomes proportional to average velocity only and in turn the volumetric flow rate.

Electromagnetic flow meters are based on the laws of electromagnetic induction, conductive liquids are the only liquids for which flow can be detected. Whether it is a conductive liquid or not is determined by the presence of electrical conductivity. Minimum conductivity of fluid should be 0.5 us/cm

Advantage:

  Unaffected by the temperature, pressure, density, or viscosity of the liquid.
  Able to detect liquids that include contaminants (solids, air bubbles)
 There is no pressure loss
 No moving parts (improves reliability)

Disadvantage:

 Cannot detect gases and liquids without electrical conductivity
 Ashort section of straight pipe is required

Reflex level gauges are commonly used for level detection within a specific vessel, and the primary principle is based on the difference in refractive indices of vapor and liquid.

Reflex gauges, also referred to as prismatic level gauges, offer a well-defined image of water levels. This reduces risks of distortions or reading areas. Because of this, a reflex level gauge can be installed in a tilt-view or vertical position to produce even greater accuracy in readings along with a much better degree of reliability. As imagined, this is highly beneficial for many industries.

Using the prism glass, a reflex level gauge accurately measures liquid inside the vessel. When light hits the glass where there is no liquid, the prism reflects the light directly out of the gauge. Known as the "dry" area, a silver color is displayed while the "wet" part is displayed in black. The contrasting colors create a clear delineation line that makes it easy to view the measurement.

The Magnetic Level Gauge is the instrument to read a level indication in whatever plant or operating conditions giving free maintenance, preventive security against leakage, environmental safety, sure and trouble free application with chemically aggressive, pollutant, harmful or poisonous, inflammable or explosive, optically similar fluid interface.

OPERATING PRINCIPLE :

The operation of the magnetic level gauge is based on some elementary physical principles:
 The principle whereby the liquid in communicating vessels is always at the same level
 Archimede's principle according to which a body immersed in a liquid receives a buoyancy equal to the weight of displaced liquid.
 The principle of attraction between North and South poles of two permanent magnets and that of repulsion between like poles.

This principle has two applications in the magnetic level gauge:
 First between the magnet in the chamber float and every single magnet of the indicating scale.
 Second between the magnets of the indicating scale.

Product Details:

 It employs two dissimilar metals.
 When two such dissimilar metals welded together at once end and subjected to heat, it develops a small DC voltage (EM corresponding to temperature difference between hot junction (measuring junction and cold junction (reference junction).

ORIFICE PLATE

Orifice Plate is the heart of the Orifice Meter. It restricts the flow and develops the Differential Pressure which is proportional to the square of the flow rate. The flow measuring accuracy entirely depends upon the quality of Orifice plate, its installation and maintains. When measuring wet gas or saturated steam a weep hole is drilled in a concentrically bored orifice plate. This is a small hole drilled on the orifice plate such that its location is exactly on ID of the main pipe.
The Orifice plates are manufactured as per ISA / AGA/ API / ANSI standards and in various materials such as SS304 /SS316 / SS316L /Hestoly C / Monel / PTFE coated.

RESTRICTION ORIFICE PLATE

A Restriction Orifice Plate is similar to an orifice plate but is much thicker. It is used to drop upstream pressure of a system. While passing the fluid through thick plate energy is lost in friction and heat resulting considerable pressure drop.
Normally single Orifice Plate having larger Thickness is used. However when the Flow velocities crosses the limit of critical flow and are subjected to sonic velocities to avoid noise vibration and cavitations in the liquid the Restriction Orifice Plates are designed in multistage form.
For Viscous fluids and low Reynolds number the upstream side of the Restriction Orifice plate is beveled.
The discharge coefficient of the restriction orifice plate is, also as per the orifice plate, approximately 0.6 according to ISO 5167. The bore is designed as per ISO 5167 and thickness as per R.W Miller/Ward-Smith.
When the noise through single hole is beyond the acceptable limit sometimes Multi Hole plates are used as restriction orifice plates .The process condition defines the no of holes. Multistage with multi holes restriction is also a possible combination.

Product Details:

Sight flow indicators is a device installed into a pipe to provide a visual of verifying liquid flow for direction and accurate flow rate. Sight flow indicators allow operators to observe the color and clarity of liquids through a window. A sight flow indicator is a body with one or more viewing windows, usually with gaskets, and a way to mount the indicator to the pipeline, such as flanged, threaded, or sanitary clamp connections. Sight flow indicators are available to fit standard pipe sizes ranging from 1/4-inch to 16-inches and carry ANSI pressure ratings. Sight flow indicators allow direct observation that do not give a false reading, lose power, or unable to read. Sight flow indicators may be applied to almost every phase of movement, whether it is liquid, gas or powder. Operators of the Sight flow indicator can see the direction of flow, and condition without interrupting process flow.
