DESPRICTION :

Flowtech Make By-pass Rotameters are suitable for flow rate measurement in 2’’ NB or 24” higher size pipes. The instrument is simple in construction and reliable in flow rate indication. The complete assembly consists of carrier rings/flanged taps, bypass line and a Rota meter as indicator. The orifice plate dimension is based on BS/ISO- 5167 specification.

PRINCIPLE OF BY-PASS ROTAMETER :

 By Pass Rotameter is an inference type Rotameter & fixed Orifice in a pipeline.
 Differential pressure (DP) is created in the main pipe line by providing an Orifice Plate in the main Pipe line. Because of this differential pressure a branch of flow moves through by- pass line provided across the orifice plate from upstream side to down -stream side of Orifice Plate.
 An additional range orifice plate is provided in the by-pass line which is designed such that flow through by –pass line (through range orifice plate) flows in proportion with the flow through main pipe line (Main Orifice Plate).  Hence by measuring the flow from By-pass Line we can estimate the flow through Main pipe Line.

BY-PASS METERING COMPONENTS:

The By-pass flow meter consists of a mainline Orifice plate, a set of Orifice Flanges Or a carrier ring, a flow meter, range Orifice, Bypass piping with Isolation Valves.

 Mainline Orifice Plate: - The purpose of the mainline orifice plate is to create the pressure differential. As the flow rate varies across this mainline orifice, the pressure differential across this plate also varies and it is this variation, which makes the meter function.

 Orifice Flanges / Carrier Ring: - Orifice flanges / carrier rings serve two functions. First, they hold the mainline orifice plate in the proper position within the pipeline. Secondly they channel a portion of the flow out of the high-pressure side of the orifice and return it again to the low-pressure side. This function may be accomplished with other than flange taps. The Bypass piping may be connected directly to the pipeline in the form of pipe taps, radius taps OR vena contract taps.

 Variable Area Flow Meter: - As discussed above, a flow meter (Glass Tube Rotameter) is placed in the Bypass piping to measure the bypass flow.

 Range Orifice: - The range orifice is a small orifice placed in the bypass piping either before OR after the flow meter. This orifice is sized so that the total pressure drop through the bypass-piping equals the pressure differential across the mainline orifice  

Specifications:

  • Flanged OR Screwed
  • Suitable for larger pipeline of 50 NB to 600 NB
  • The Flowrate through the Rotameters is proportional to the pressure drop across the orifice plate
  • Available in SS-316/ SS-304/P.P material
