Acrylic Rotameters are precision machined from clear acrylic block and fitted with
needle valves stream lined in appearance. They are designed to give maximum
Accuracy visibility & Ruggedness.
Stainless steel, Teflon, PVC or as per requirement. In bigger models guide rods
are provided for better stability.
For Accurate flow control precision machined needle type valves are
Standard Accuracy of 1.5 to 1% at full Scale. Better accuracy on specific
Top / Bottom or Rear as per requirement in S.S. screwed, Nozzle, with Suitable "0"
Rings to avoid leakage.
Carried out at works individualy using air and water at standard condition. Reliable
impirical conversion, are used to calibrate for other fluids.
Rotameter are ideal for direct Panel mounting because of their neat modular
apperance, online is also possible.

METAL TUBE ROTAMETER
Principle of measurement:
The variable area flowmeter measures the flow rate of liquids and gases in pipe lines. It contains a vertical metal tube.
with an orifice (or a conical tube which widens towards the top) through which the measured medium flows.
The float (which can move in the tube in the vertical plane) settles at a specific level, if the forces acting on it are in equilibrium, such that the weight of the float is identical to the sum of the buoyancy force and the flow force. The level of the float in the conical measuring tube is proportional to the flow rate. A magnet located in the float and a magnet follow-up system enable the float’s level in the tube to be indicated via a pointer. A cam mechanism
linearizes the flow rate. The flow rate is then read from the scale according to the pointer position.
