How does an orifice plate flow meter work
WebWhere a meter may be subject to possible over-speeding because of sudden pressure drops or flow surges, a restricting orifice should be installed downstream of the meter in accordance with the manufacturer’s recommendation. A properly sized orifice plate or nozzle will protect a meter from damage due to over-speed by WebFeb 5, 2024 · How are orifice plates measured? Orifice plate meter flow measurement. An orifice meter is a circular piece of metal plate placed between flanges in a pipe. In it is a square-edged round hole machined 0.5 to 0.8 pipe diameter in size. Pressure tapping points are placed either side of the plate at specified distances.

WebSep 26, 2010 · Flow-profile distortion and swirl — the two most prominent types of fluid disturbance that affect a meter’s flow coefficients — are typically the products of improper piping configuration. ... when a single 90-degree elbow precedes an orifice plate, the straight-pipe requirement ranges from six to 20 pipe diameters as the beta ratio ...
WebMar 28, 2024 · An orifice is a plate with a hole or cutout attached to the outlet or inserted inside a pipe such that the flow passes through the orifice. The orifice, usually circular, is of known diameter and area to keep the flow regulated. As the fluid flows through an orifice, the pressure drops across the pipe. This phenomenon is also used to measure fluid … WebThe orifice plates are simple, cheap and can be delivered for almost any application and in any material. The Turn Down Ratio for orifice plates are less than 5:1. Their accuracy are poor at low flow rates. A high accuracy depend on an orifice plate in good shape, with a sharp edge to the upstream side. Wear will reduce the accuracy. Orifice ...
