Variable Area Water Flowmeters

Variable Area Water Flowmeters

Install these flowmeters inline to measure water flow in your systems. Also known as rotameters, these devices have internal floats that are pushed by the flow of water. Flow rate is determined by reading the provided scale to see where float equilibrium is reached. Resistant to shock and vibration, these flowmeters offer a simple design that doesn't require special piping. They're ideal for areas where no electrical power is available.

General Purpose

Use these easy-to-read, basic variable area flowmeters to measure water flow. They have a clear body to allow inspection of the fluid, can be mounted in any position, and automatically return to zero using an internal spring.
