| Stainless steel orifice plate mounted in polypropylene carrier for gas or liquid flows. Temperatures up to 90°C and line pressures up to 10 bar. Carrier predrilled to customer-specified flange table. | Solid one piece stainless steel orifice plate for high temperature - high pressure demanding applications. Mounted within the bolt circle of the pipeline flanges. Stub pipes bring the tapping points beyond the flange O/D. |
| 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 electronic 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. | |
| When ordering please state: type and specific gravity of liquid or gas flowing, pipe I/D, normal maximum flow, temperature and pressure, indicator required or D.P range. | |
