The common types of flowmeters that find industrial applications can be listed as below: … WebFor a specific temperature and pressure condition, the orifice area at the outlet determines the volumetric flow rate of the fluid inside the pipe. Due to the high-pressure drop at the …
WebThe flow rate is a function of the square root of the differential pressure across the orifice plate. This rate can then be determined by use of an appropriately scaled differential … WebFigure 1: Compressible Flow through an orifice The basic equation for calculating the pressure drop through an orifice or venturi is the Bernoulli equation, p V 2 gh 2 1 = constant (1) If subscript “1” refers to the upstream conditions and …
WebThe orifice plates shall be used as the primary flow sensing elements. These sensing elements shall provide a safe and reliable means of creating differential pressure for use in flow measurement. 3.1 Orifice Plates The orifice plate assemblies shall conform to the following requirements unless specified otherwise in the corresponding data sheets. WebThe flow rate of a known orifice is typed into the computer and timed as the water rises from the lower photocell to the higher photocell. The known flow rate multiplied by time gives a volume. In subsequent flow calibration tests this volume is divided by computer measured time and converted into a rated flow and orifice diameter. 2.
