About us

Glass Tube Rotameter

We are among top leading manufacturers & exporter of all types of Rotameters in India. We have customized manufacturing capability and solution to satisfy customer needs as given. We are committed for delivering quality flow meters with durability. These flow meters consists of a vertical mounted, calibrated tapered tube with float inside and a scale directly calibrated as per flow range taking into account operating Sp. Gr. /Density and operating viscosity with Accuracy of +/- 2% Full Scale Range.

We have wide range of rotameters for different-different applications in various Industries that makes us amongst top most Rotameter supplier in India. Our mfg. range includes glass tube, magnetic, low flow, acrylic body, gas, multiple & metal tube, air purge, digital, bypass, water Rotameter & Rotameters For valve leak testing.

  • By-Pass Type Rotameter
  • Digital Magnetic Rotameter


  •  By-Pass Type Rotameter Complete Assemblies

By-Pass Type Rotameter Complete Assemblies are recommended for large flows in 2” & above size pipe lines, where direct on-line Rotameter is not possible.

Assembly consists of

 a) A pair of 38mm thick orifice flanges with ½” BSP female pressure tapings

 b) A precisely bored & finished orifice plate

 c) Necessary by-pass piping

 d) 2 Nos. Isolating valves

 e) A Rotameter in By- Pass line with range orifice plate. All items assembled together & 2 above MOC as required by fluid / client. By pass piping design (position) differs for vertical installation & horizontal Installation.

Digital Magnetic Rotameter

High accuracy digital metal tube rotameters are used in place of glass tube rotameters wherein there is high pressure and high temperature in the line which glass tube Rotameter cannot perform. This magnetic flow meter uses magnetic float which is detected by highly sensitive magnetic field detection sensor which enables to show digital reading. These flow meter does not require any electrical connection, as it operates on replaceable battery. This flow meter has in built two wire transmitter i.e 4-20 mA output.
