ACRYLIC ROTAMETER

Acrylic Rotameter is a Variable Area Flow Meter. A rotameter consists of a tapered tube, typically made from acrylic block, with a 'float' made of SS or PTFE. The differential pressure across the annulus area is constant. The float moves through the tapered tube up & down with respect to fluid flow. The vertical position of the float as indicated by scale is the measure of the instantaneous flow rate.

BY-PASS ROTAMETER

By-Pass Rotameter is an Inference type flow meter. Differential pressure (DP) is created by providing an Orifice Plate in the main line. Due to the differential pressure, fluid flows through branch pipes provided across the upstream and downstream sides of the Orifice Plate. An additional Range Orifice plate is provided in the by-pass line as flow through the by-pass line will be in proportion with Main Line.

GLASS TUBE ROTAMETER

Glass Tube Rotameter is a Variable Area Flow Meter. A rotameter consists of a tapered tube, typically made of glass, with a 'float' made of SS or PTFE.  The differential pressure across the annulus area is constant. The float moves through the tapered tube up & down with respect to fluid flow. The vertical position of the float as indicated by scale is the measure of the instantaneous flow rate.

METAL TUBE ROTAMETER

Metal Tube Rotameter is a Variable Area Flow Meter. A rotameter consists of a tapered tube, typically made of steel with a 'float', made of SS or PTFE.  The differential pressure across the annulus area is constant. The float moves through the tapered tube up & down with respect to fluid flow. The vertical position of the float as indicated by scale is the measure of the instantaneous flow rate.

ORIFICE

An orifice plate is a device used for measuring flow rate. Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate. It is based on Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the velocity increases, the pressure decreases and vice versa.  

It is also used for reducing pressure or for restricting flow. It is often called a restriction plate.
