How is an orifice plate made?

This type of orifice plate is manufactured by machining a precise, straight hole in the middle of a thin metal plate. Looking at a side view of a square-edged concentric orifice plate reveals sharp edges (90 o corners) at the hole:

How do I choose the right orifice plate?

If the quantity of undesirable material in the flowstream (bubbles, droplets, or solids) is excessive, an eccentric or segmental orifice plate might be a better choice. Some orifice plates employ non-square-edged holes for the purpose of improving performance at low Reynolds number values, where the effects of fluid viscosity are more apparent.

What does a square-edged orifice plate look like?

Looking at a side view of a square-edged concentric orifice plate reveals sharp edges (90 o corners) at the hole: Square-edged orifice plates may be installed in either direction, since the orifice plate “appears” exactly the same from either direction of fluid approach.

How do you drill a hole in an orifice?

An alternative to offsetting or re-shaping the bore hole of an orifice plate is to simply drill a small hole near the edge of the plate, flush with the inside diameter of the pipe, allowing undesired substances to pass through the plate rather than collect on the upstream side.

What is orifice plate?

In this post, we will have a detailed look at Introduction to Orifice Plate. An orifice plate is a module that is used for gaging of the rate of flow of different fluids, dropping pressure, or for limiting flow for these two works it is also known as a restriction plate.

How is the flow rate of a orifice plate determined?

Orifice plate. Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate. It uses the same principle as a Venturi nozzle, namely Bernoullis principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid.

Why do some orifice plates have holes in them?

Some orifice plates employ non-square-edged holes for the purpose of improving performance at low Reynolds number values, where the effects of fluid viscosity are more apparent. These orifice plate types employ rounded- or conical-entrance holes in an effort to minimize the effects of fluid viscosity.

What material is an orifice plate meter made of?

The orifice plate meter can be made of any material, although stainless steel is the most common. The thickness of the plate used ( 1/8-1/2) is a function of the line size, the process temperature, the pressure, and the differential pressure.

What is the purpose of orifice drain hole?

- InstrumentationTools What is the Purpose of Orifice Drain Hole ? Drain hole is a small hole which is provided in the lower region of orifice plate. Drain hole is required in gas flow service where liquid entrapment may occur.

Do vent or drain holes affect the performance of an orifice plate?

The addition of a vent or drain hole should have negligible impact on the performance of an orifice plate due to its small size relative to the main bore. If the quantity of undesirable material in the flowstream (bubbles, droplets, or solids) is excessive, an eccentric or segmental orifice plate might be a better choice.

How is an orifice plate made?

This type of orifice plate is manufactured by machining a precise, straight hole in the middle of a thin metal plate. Looking at a side view of a square-edged concentric orifice plate reveals sharp edges (90 o corners) at the hole:

How do you drill a hole in a fence?

1) Adjust the location of your fence and drill for the first hole. All subsequent holes will be closer to the fence (see illustration) so plan accordingly. 2) Fasten the drilling material securely. If you are drilling through the material be sure to have something under it thats safe to drill into.
