Variable Area Flowmeters

Available148 products

Variable area flowmeters (rotameters) measure the flow rate of chemically compatible media (e.g. gases, oils, liquids) moving through a system. Flowing media pushes the meter's float or spring-loaded indicator to a value on a scale to provide a flow rate measurement.

Compatible Media Types

Inline Flowmeters for Water

Inline Flowmeters for Water
Inline variable area flowmeters for water measure the flow rate of water and water-based liquids traveling through a system. Inline meters and sensors are installed level with the system's piping, where media travels directly through the instrument. They're used in applications with limited space, minimize the impact on system line pressure, and require minimal plumbing alterations.

Inline Flowmeters for Water with Remote Output

Inline Flowmeters for Water with Remote Output
Inline variable flowmeters for water with remote output measure the flow rate of water and water-based liquids traveling through a system. Remote output sends signals to alarms, warning lights, or programmable logic controllers (PLC) when media stops or starts flowing. Inline meters and sensors are installed level with the system's piping, where media travels directly through the instrument. They're used in applications with limited space, minimize the impact on system line pressure, and require minimal plumbing alterations.

Panel-Mount Flowmeters for Water

Panel-Mount Flowmeters for Water
Panel-mount variable area flow meters for water measure the flow rate of water and water-based liquids traveling through a system. Panel mount meters and sensors install perpendicular a pipe within a system or mounted on a panel board (with the proper fittings) alongside other instruments to provide several readings in one location.

Panel-Mount Flowmeters for Air & Water

Panel-Mount Flowmeters for Air & Water
Panel-mount variable area flow meters for air and water measure the flow rate of air, water, and water-based liquids traveling through a system. Panel mount meters and sensors install perpendicular a pipe within a system or mounted on a panel board (with the proper fittings) alongside other instruments to provide several readings in one location.
