Paddle Wheel Flow Meters

Paddle Wheel Flow Meters have a freely rotating paddlewheel set in the path of a fluid stream. The flowing liquid or gas causes the paddle wheel to spin upon its axis. The rate of spin will be proportional to the flow rate. Paddle Wheel Flow Meters come in a range of materials to ensure chemical compatibility in normal or aggressive liquids.

Paddle Wheel Flow Transmitter | FSE

Paddle Wheel Flow Transmitter - Overview

Paddlewheel flow transmitters use the flow of the liquid to rotate a paddlewheel (just like a riverboat) in the flow stream. As the fluid moves faster, so does the paddlewheel. Measuring the rotations of the paddlewheel then gives an accurate indication of the speed of the flow.

Paddle Wheel Flow Transmitter - Features
- IP68 enclosure, SUS, and chemical-resistant body
- Low power consumption
- Stable & high-resolution rotor
- Bi-directional
- Easy maintenance
- Easy to use
- Connect to PLC / IPC directly

SS High Performance Paddlewheel Flow Sensor | Signet 2540

SS High Performance Paddlewheel Flow Sensor - Overview

This Stainless Steel Paddlewheel Flow Sensor is both strong and corrosion-resistant. It is suitable for use in liquid applications with low-velocity measurements. Unique internal circuitry eliminates the need for magnets in the process fluid, enabling flow measurement of 0.1 to 6 m/s while maintaining the advantages of insertion sensor design. Ultraflon 500C bearings and a Tungsten Carbide pin provide exceptional wear resistance. The Signet 2540 offers field replaceable electronics and transient voltage suppression (TVS) to provide greater immunity to large voltage disturbances (i.e. lightning) sometimes encountered in field wiring. Sensors can be installed in DN40 to DN600 pipes using the 1½ in. or ISO 7/1-R 1.5 threaded process connection.
The sensors are also offered in a hot-tap configuration with a bleed valve service without process shutdown in pipes up to DN900 (36 in.). Both styles of sensors must be used in full pipes. They can be used in low-pressure systems.
