Purge Rotameter

Purge rotameter

Description of Purge Rotameter

Process Control Devices offers a series of variable area flow meters in Mumbai. Designed to measures the flow rate of a fluid flowing through Vertical pipelines. Purge rotameter are cost-effective and convenient for low flow rate sign for fluids. Where operating conditions are with the limitations of Glass metering tube of rotameter. The float moves smoothly in an upward and downward direction in tapered Glass Tube with fluid flow from bottom to top.

The float takes up a position where buoyancy forces and the float weight is balance in proportion to flow rate. The top position of the float as indicated by scale is the measure of the instant flow rate. These also known as low flow rotameter. We provide flow calibration report with each rotameters with one-year validity. It is being used for purging / isolating or controlling of fluid passing through process pipes. We manufacture purge rotameter with a vertical connection, rear connection and offsets connection with isolation valves.  This is also known as low flow rotameter.

This rotameter comes with factory calibration certificate and one year warranty. We are reputed manufacturer of purge rotameter in Mumbai India
