When measuring liquid or gas flow at higher pressures and temperatures than is suitable for plastic, you can achieve accurate flow rates with robust glass tube rotameters (variable area flow meters) from Brooks Instrument. With a broader range of flow rates available, glass tube rotameters are suitable for a variety of liquids and gases.
Resistance to thermal shock, pressure and oxidation is the result of employing borosilicate glass tube bodies that can withstand pressures up to 13.8 bar (200 psi). Plus, corrosion-resistant material options for scales, floats, fittings and valves accommodate a variety of applications, whether in the lab or in industrial processes.


Durable and accurate flow meters for fluid measurement in high-pressure and extreme temperature applications.
Armored to deliver repeatable, reliable flow measurement in demanding high-pressure, high-temperature applications, metal tube variable area flow meters from Brooks Instrument set the global standard for rugged durability and sustained accuracy.
Globally approved for use in hazardous environments, metal tube rotameter (variable area flow meter) manufacturer Brooks offers a range of metal tube rotameters that include corrosion-resistant options for metering aggressive fluids and multiple connection options to make it easier to interface our meter into existing industrial systems. Engineered for long-lasting performance, Brooks high-pressure water or gas flow meters deliver excellent meter repeatability to help accurately measure and precisely control complex industrial processes.


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.

Orifice plates are one of the most popular devices for the measurement and control of fluid flow. The shape and manufacturing tolerances of plates used in measurement applications are defined in the international standardization publications of ISO, AGA, ASME and others. From the formulas and data within these publications, the relationships and values of flow, differential pressure, and plate bore are determined.
In flow control applications, orifice plates are used as restriction devices to regulate fluid flow or reduce the flowing pressure downstream of the orifice plate. The use of a fixed restriction orifice can be beneficial and economic by reducing the demands on other flow system components.
