A variable area flow meter (Figure 1) is a type of differential pressure (d/p) flow meter. Variable area flow meters are simple and versatile devices that operate at a relatively constant pressure drop and provide flow measurement of liquids, gases, and steam.

From inline flow meters to low volume flow meters, Brooks offers high-performance gas and water variable area flow meter technology for the broadest range of industrial flow meter applications.

Jul 15, 2015 · Variable area flowmeters are very simple yet versatile flow measurement devices for use on all types of liquids, gases, and steam. They operate on the variable area principle, whereby a flowing fluid changes the position of a float, piston, or vane to open a larger area for the passage of the fluid.

Yokogawa VA flow meters offer simple installation and trouble-free operation while delivering highly accurate flow measurements in low flow, high pressure, and other applications.

A variable area flow meter is one where the fluid must pass through a restriction whose area increases with the flow rate. This stands in contrast to flow meters such as orifice plates and venturi tubes where the cross-sectional area of the flow element remains fixed.

Nov 7, 2024 · Learn all about Variable Area Rotameter Flow Meters: what they do, how they work, why they are called variable area meters, types, advantages, capabilities, accuracy, how to choose the right one, how to read one, installation, different media capacities, switches, calibration, pricing, and more. What is a Rotameter Used For?

Dec 28, 2022 · Basically, the design of a variable area flow meter is a tapered glass tube with a self-centering float pushed upwards by the fluid flow and pulled downwards by the action of gravitation.

Variable area flow meters are simple and versatile devices that operate at a relatively constant pressure drop and measure the flow of liquids, gases, and steam. The position of their float, piston or vane is changed as the increasing flow rate opens a larger flow area to pass the flowing fluid.

Jul 22, 2021 · The variable area flow meter is a meter that measures fluid flow by allowing the cross-sectional area of the device to vary in response to the flow, causing a measurable effect on the rate.

Jun 8, 2023 · A variable area flow meter is a widely used instrument for measuring fluid flow rates in various industrial processes. It provides a simple and reliable solution for monitoring the flow of liquids, gases, and steam.
