ORIFICE PLATE
 

 


 

Description

Orifice flange assembly is sused in conjunction with orifice plate for flow measurement of smaller or medium size pipes at lower or medium pressure ranges. The flange connection is a RF type and the differential pressure tapping system is the flange taps.

Orifice plates are widely used for flow measurement as they provide the simplest and the most economical means of flow detection. Orifice plates are available in the concentric type that the round opening (Bore) of the orifice plate is positioned concentrically with the center of the pipe and the opening edge (Bore edge) is available either in the concentric square edge type (sharp, square edge type) or in the quadrant edge type (Round edge type).

 

 

 

Orifice bore type

Concentric square edged orifice

Quadrant edged orifice

Eccentric orifice

Segmental orifice

 

 

Plate material

Standard : 304SS and 316L SS

Monel, Hastelloy c, Teflon and etc.

RING ORIFICE


 

 

Description  

Orifice ring assemblies are used for flow measurement of smaller or medium sized pipes at lower pressure. Each assembly consists of one orifice plate and two orifice rings. Differential pressure is taken out in a corner tap system. Orifice block, which ard of a unit-construction type and provide highter pressure ratings than the orifice ring assemblies, also are available.

Plate thickness

   3, 6, 9, 12 mm and Over

 




AVERAGE PITOT TUBE 


 

Description

Averaging pitot tube is an energy saving device used to measuring the flow of liquids, gases and steam in pipes, stacks and rectangular ducts. It provides high, long term stability with low permanent pressure loss. Examples of their applications are precise volumetic flow measurement in batch processes, continuous  measurement of liquid ingredients in the process industry, fuel, air steam and gases as primary energy source as well as in control functions requrring a high degree of stability and repeatability.

 

 

Features

Unique profile shape enables high flow rate turn down

Dual averaging for better accuracy

One-piece outer tube for optimum strength

Long term accuracy unaffected by wear  

Short upstream and downstream straight pipe lengths

  


 

Measuring fluid

Liquid, Gas, Steam, etc

 

Specification

Repeatability of measurement ±0.1%

Flow rate turndown typically 10:1  

Long term accuracy unaffected by wear

  

 

CONE TYPE FLOWMETER


Description

The cone is a differential head flow meter consisting of a circular cone placed in the center of a pipe section with two pressure taps. The upstream pressure tap is placed at a point where flow is undisturbed by the cone, and the downstream tap at the end of the cone facing downstream. The liquid or gas flows through the annular gap formed between the pipe wall and the cone, inducing a differential head that is proportional to the flow rate.

 


Features

Unique profile shape enables high flow rate turn down

Dual averaging for better accuracy

One-piece outer tube for optimum strength  

Long term accuracy unaffected by wear  

Short upstream and downstream straigth pipe lengths

 

Specification

Standard accuracy :  ±0.5% of actual flowrate  

Repeatability : 0.1% or better  

Head loss : Approximately 20% of the generated differential pressure  

Materials of construction included : Standard-304SS, 316SS, Carbon, Special materials on request  

End fittings : Flanged, Threaded, or weld-end standard others on request
