Air Flow Rotameter
BY PASS Rotameter for Chemical process Industries, Flowtech Make By-Pass Rotameters.
Make Bypass Rotameter as designed for measurement of flow rate of Liquid and gases in 2 NB or higher Size pipe sine.
“Flowtech” Make By-pass Rotameter as designed for measurement of flow rate of Liquid and gases in 2” NB or higher Size pipe sine. The complete assembly consist of carrier rings [orifice Flanges], orifice Plate, by-pass piping with Isolation valves & a Rotameter as indicator. The orifice plate is design on IS of BS specification.
These meters are selected for low cost measurement of high flow rates generally in the 2” and larger sizes. It provides linear measurements of fluid in conjunction with an orifice plate in the main line. The Rotameter is modified to include a range orifice which is sized so that the flow through the meter at the maximum pressure drops across the orifice plate in necessary to lift the float to the maximum position. Hence the flow through the range orifice is proportional to the instantaneous flow through the main orifice and so the bypass Rotameter measure main line flow.
Suitable for larger pipeline of 50 NB to 450 NB.
