A fl\u00f6desm\u00e4tare<\/strong> m\u00e4ter volymen, massan eller hastigheten hos en v\u00e4tska (v\u00e4tska eller gas) n\u00e4r den r\u00f6r sig genom en r\u00f6rledning eller ett system.<\/p>\n\n\n\n

A trycktransmitter<\/strong> m\u00e4ter det tryck som en v\u00e4tska ut\u00f6var i ett system, som kan vara statiskt (stillast\u00e5ende) eller dynamiskt (i r\u00f6relse).<\/p>\n\n\n\n
