Variable Area Flowmeters

Vendors: Blue-White
F-440-Adjustable1

Variable area flowmeters are mechanical devices that measure flowrate of liquids or gases installed vertically in a pump application. They are sometimes used as a backup to digital flowmeters since they won’t fail due to power loss. We stock a wide variety of variable area flowmeters for many application types.
