 P.O.A.

Measurement of pressure drop across an orifice plate is one of the most

widely accepted methods of determining flow. With no moving parts and a

design based on fundamental physical principles, high reliability is assured.

The orifice size is computer calculated for each specific application in

accordance with BS EN ISO 5167/1.

For best accuracy these standards recommend installation with minimum 20

pipe diameters (D) upstream and 10 diameters (D) downstream of smooth

straight pipe. 12 D upstream and 6 D downstream will give a typical accuracy

of ±2%, while 6D and 3D will give approximately 4%, depending on pipe

layout.

System pressure loss will be typically 45 - 70% of the actual differential

pressure across the plate depending on the application. We can design to

keep this to a minimum if required or utilise the full scale range of the flow

indicator being used.

Polypropylene and stainless steel carriers are 25mm nominal thickness.

Metering stations for pipe sizes up to 300mm dia. are part of our normal

supply and units for larger pipe diameters are possible depending on the

application.

Manometers, dial gauges and Digital flow indicators or transmitters may

all be used with orifice metering stations. Poddymeter will advise on a

suitable gauge from within our own range or from an outside source.



Valves to suit the Orifice Plate are available on our accessories page

When ordering please state: pipe size (ID), flange table (e.g. PN16 etc.) type

and specific gravity of liquid or gas flowing, normal maximum flow,

temperature and pressure, the indicator (if required e.g dial gauge) and the

D.P range.

Please call us if you have any queries.
