By Pass Rotameter
By-Pass Rotameters are ideal for measuring large flow rates at an economical cost.
The Bypass Rotameter 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.
The differential pressure across the main orifice plate is proportional to the flow rate in the main pipeline. The flow rate indicated in the by pass rotameter is calibrated in terms of flow through the main pipeline, a range orifice is used at the inlet of the Rotameter.
Recommended for large flows in 2” & above size pipe lines, where direct on-line Rotameter is not viable due to high cost and non availability of required diameter Tube.
