Description

NRG GLOBAL MAKE By-Pass Rotameter is an Inference type flow meter. Differential pressure (DP) is created by providing an Orifice Plate in the main line. Due to the differential pressure, fluid flows through branch pipes provided across the upstream and downstream sides of the Orifice Plate. An additional Range Orifice plate is provided in the by-pass line as flow through the by-pass line will be in proportion with Main Line. • Bye pass rotameters are used for measurement of higher flow rates where using inline flow meter is not commercially or functionally not viable. • It works on the principle of measuring differential pressure created across restriction. • The construction includes an orifice plate installed between either carrier ring or orifice/pipe flanges. • The Hi/Low pressure taps of carrier ring/orifice flange/ pipe are connected to indicating Rotameter with a help of impulse tube arrangement. The Indicating Rotameter can be of Glass or Metal tube Type. • NRG make Bye pass Rotameters can be used for liquids or Gases and is available from 2” to 40” sizes. • Applications: Water/Pharma/Chemical/Fertilizers/Power/Petrochem/Refinery Specifications : By- Pass Rotameter Type: Glass Tube / Metal Tube / Acrylic Flange: CS /A 105 / SS 304 / SS 316 Carrier Ring: CS /A 10S / SS 304/SS 316 Line Size from 80 NB to 300 NB Main Orifice Plate: SS 316 / SS 304 / PTFE Range Orifice Plate: SS 316 / SS 304 / PTFE Accuracy :+/- 5% of FullScale Measuring Span : 1:10 Scale: Acrylic / Aluminum / SS Measuring Span : 1:10
