Mass flow rate is the ideal measurement value because it is independent of pressure and temperature, although volume flow rate is usually technically more convenient to measure and, therefore, is preferred. FLUID FLOW MEASUREMENT Flow measurement has a history of about years. It has been studied only in the last years and in the last 30 years all the new techniques have evolved. There is now a wide variety of methods available to measure the flow of.

The vast body of data supporting Orifice measurement over the years becomes meaningless if the guidelines for the design, manufacture, installation, and maintenance of these devices are not followed. Venturis also require much less straight pipe upstream. The measured differential pressure differs for each combination and so the coefficient of discharge used in flow calculations depends partly on the tapping positions. Bookmark no Gambar 2.

FM - Flow Measurement by Venturi and Orifice meter Objectives: 1. To find the coefficient of discharge for venturi meter. 2. To find the coefficient of discharge for orifice meter. Theory: Venturi meter and orifice meter are the commonly used flow meters. The differential pressure measurement method is a universally utilized measuring principle for flow measurement. The orifice flow meter is a type of differential pressure flow meter that can be used for measuring gases and liquids. An Orifice Meter is basically a type of flow meter used to measure the rate of flow of Liquid or Gas, especially Steam, using the Differential Pressure Measurement principle. It is mainly used for robust applications as it is known for its durability and is very economical. As the name implies, it consists of an Orifice Plate which is the basic element of the instrument. The flow coefficient C f is found from experiments and is tabulated in reference books; it ranges from to for most orifices. Since it depends on the orifice and pipe diameters (as well as the Reynolds Number), one will often find C f tabulated versus the ratio of orifice diameter to . Mass flow rate is the ideal measurement value because it is independent of pressure and temperature, although volume flow rate is usually technically more convenient to measure and, therefore, is preferred. 1 EXPERIMENT No.1 FLOW MEASUREMENT BY ORIFICEMETER AIM: To determine the co-efficient of discharge of the orifice meter EQUIPMENTS REQUIRED: Orifice meter test rig, Stopwatch PREPARATION THEORY An orifice plate is a device used for measuring the volumetric flow rate. measurement of flow of high density gases. The turbine meters are widely used for the measurement of the volumetric flow rate of clean gases (±% of rate) and liquids (±1% of rate). The flow rate measurements based on orifice meters are less accurate (% URV) but. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases. A little downstream of the orifice the flow reaches its point.
