Add an Orifice plate to any pipe, or specify a fixed pressure drop.

A venturi tube has less head (pressure) loss than an orifice plate.

Can reduce storage by up to 30% compared to an orifice plate, thereby cutting capital costs.

Flow rates are set by the orifice plate.

An orifice plate meter has a practical turndown ratio of 3:1.

Alternatively the losses associated with the abrupt change in sections of the orifice plate are large.

In all testing the common requirement was a fully developed flow profile entering the orifice plate.

Orifice plate which can function as a mechanical clipper for acoustic signals.

These long vortices create a high amplitude, low frequency signal from the orifice plate.

Some of these reservoirs are constructed across the river line, with the onward flow controlled by an orifice plate.

Moore Effect of system layout on the discharge coefficient of orifice plates.

Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate.

Most commercial machines use orifice plates due to their simple construction and the ease of providing multiple flow ranges.

Two common differential pressure methods for flow measurement are venturi tubes and orifice plates.

The golden dish (right) is the orifice plate, with the tiny one millimetre central hole through which the test sample passes.

Orifice plate includes derivation of non-choked gas flow equation.

They are more accurate over wide flow ranges than orifice plates or flow nozzles.

Under choked conditions, valves and calibrated orifice plates can be used to produce a desired mass flow rate.

In the natural environment, large orifice plates are used to control onward flow in flood relief dams.

Once full flow has been established the check valve closes and the system flow rate is controlled by the orifice plate.

Gas flow rates are determined from orifice plate measurements (BS1042) and pitot-static tube.

Orifice plates are essentially a flat metal disc with an accurately sized and bored circular hole.

The earlier models of the Jameson Cell used orifice plates to generate the downcomer jet.

Lack of any sudden change in cross section area of flow path that would reflect a pressure wave, i.e. no orifice plate(s).

Orifice plates are also used to reduce pressure or restrict flow, in which case they are often called restriction plates.
