M410 Orifice Plate Flowmeter and Carrier Assembly
Description The M410 orifice plate and carrier assembly is a primary flow element consisting of a tab handled square edged orifice plate and optional carrier. The orifice plate is designed and manufactured to meet the requirements of British Standard BS 1042 and International Standard Organisation ISO 5167 in all respects and is suitable for the measurement of the rate of flow for most liquids, gases and steam. The tab handled orifice plate can be used for either: a: on its own fitted between flanges with pressure tappings in the users pipework or flanges. or b: fitted into a carrier with integral flange tappings designed to fit between customer flanges. Limiting conditions The pressure and temperature limitations of both the tab handled plate and the carrier assembly are the same as the specified flange ratings. Performance To BS 1042 and ISO 5167. The performance of an orifice plate flowmetering system can be greatly influenced by installation variables, so the figures given below are for guidance only: Accuracy Typically ±3% of actual flow (equivalent to ±1.5% full scale deflection at 50% of rated maximum flow) Repeatability Typically ±0.3% Turndown Typically 4:1
