INDUSTRIAL FLOW METER

ISB/1 EP

EMCO Orifice Plate Series ISB/1 EP for RF Flanges
The EMCO Orifice Plate is used as a primary element in flow measurement of liquid, gas and steam applications based on the differential pressure principle. According to this working principle, the orifice plate creates a flow restriction in the pipeline to allow measurement of the resulting pressure drop and flow rate. Our orifice plates have been tested and tried for over 50 years and measure up to the highest industry and compliance standards.

The Orifice Plate Series ISB/1 EP is especially designed for installations with limited space due to the flow conditioning effect created by the 5 hole design. The design therefore combines a traditional single bore orifice plate with a flow conditioner which can reduce the flow meter from 20 times inner pipe diameter to 5 times inner pipe diameter upstream in a straight pipe run.

Overview

Installation
Before installation, the orifice plate must be kept clean and protected against corrosion and physical damage. It is also important that you pay careful attention to to the sharp edge of the plate. Once ensured that it is clean, install the orifice plate carefully such that the orifice bore aligns with the centre of the pipeline. Tap location varies depending on whether it is used for liquid, gas or steam. It is not supplied with any safety devices and must not be used for higher pressure, than stated on the name plate. The pipe system must therefore be equipped with a safety device. However, this type of primary element requires no special maintenance.
