Variable Area Flow Meters
Rotameters for Clean Liquids or Gases
Looking for a flow meter for measurement of volumetric flow of clean liquids or gases? A variable area flow meter (or rotameter) may be your best option. Rotameters are cost effective metering solutions that don’t require external power, have low pressure drop, and are easy to commission (and maintain). This makes them ideal for a wide range of environments, from wastewater treatment to more remote locations that may not have readily available electrical power.
Cross Company’s Process Solutions group partners with industry-leading manufacturers to provide reliable, high-quality variable area flow meters for industrial, commercial, and municipal applications.

Typical VA Meter Applications
Typical applications for a VA meter include:
- Chemical Injection
- Dosing
- Boiler Control
- Purge Applications
- Tank Blanketing
As well as any simple flow measurement application measuring gasses and/or clean, low viscosity liquids.
Common Rotameter Industry Applications
Variable area flow meters have applications in diverse industries and processes. Some of these applications include
Chemical Processing – VA flow meters are frequently used to measure the flow rates of chemicals in chemical processing plants. They are utilized to monitor the precise quantities of chemicals necessary.
Water Treatment – In wastewater treatment facilities, rotameters are used to measure the flow of water and chemicals during different treatment stages. This ensures efficient water treatment processes.
Pharmaceuticals – Variable area flowmeters are utilized in pharmaceutical production to measure the flow of liquids used in drug manufacturing processes.
Petrochemicals – Within the petrochemical industry, variable area flow meters are used to measure the flow of oil, gas, or other hydrocarbons in the refinement process.
Advantages of Using Rotameters From Cross In Your Process
VA meters are durable, robust, and simple to install/use since the flow tube span increases proportionally as the float moves up, meaning the scale is considered to be approximately linear. They are able to provide flow-rate monitoring in real time for liquids and gases with reliable repeatability.
Rotameters come in a wide range of material choices, allowing them to accommodate a variety of media. This even includes corrosive liquids (assuming build material is compatible). And multiple variable area flow meters can be used on a single line without contributing significantly to pressure loss.
Like a turbine meter, VA meters are set up for specific conditions. Any change in specific gravity, viscosity, process temperature, etc., can affect the overall accuracy of the meter. These considerations are why it’s so important to work with an experienced flow measurement professional like Cross.
