E+H渦街流量計(jì)Prowirl72簡明操作指南

【資料簡介】

 Vortex meters are used in numerous branches of industry to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralized water, solvents, heattransfer oils, boiler feedwater, condensate, etc.

Vortex meters are particularly popular in all sectors of industry for metering steam. Vortex meters measure volume flow, but steam systems are generally rated by mass or energy content, so these meters are frequently used in combination with a pressure and/or temperature sensor and a flow computer. A configuration of this nature helps save energy and is ideal for allocating the costs of generation across multiple consumers.
