Rotameter/Variable Area Flow Meter
Rotameters get their name from the rotating float that is used to indicate the rate of flow.
The float moves both up and down depending on the rate of flow, this means that rotameters are commonly used to measure low flow rates as high flow rates tend to throw off the accuracy of the readings.
These types of flowmeters are great for applications that require an economical solution whether working with gases or liquids across a number of different applications. Read More…

As stated earlier, rotameters work best within applications where a low rate of flow is present, the reading is often done locally although the transmission of readings is an option in certain applications.
These flow meters are most commonly made from glass tubes that have markings along the sides in order to indicate the rate of flow visually. Metal rotameters are also available if that is something that your application requires.
As fluid enters the bottom of the rotameter, the float rises upwards within the tapered tube until gravitational force balances out. Typically, rotameters are read as a standard cubic feet per hour of air, this means that rotameres are not subject to constant restriction areas or variable pressure differentials because of the use of variable restriction and constant pressure differentials in order to measure the flow.
These flow meters can be used for a number of different applications as they can be designed to measure the flow rate of both single streams and also multiple streams of fluid or gases. The single flow meters are often mounted directly on the piping and are most commonly used in special conditions for measurements. Multiple tube rotameters are mounted onto a tripod base plate in order to level the system; they can also be mounted on a wall or even bench mounted.
Rotameters are popular due to their versatility, simplicity, accuracy, and overall ease of use. It’s no question why rotameters are the go to choice for so many industries.
