Paddlewheel Flow Meters

19 Products
Low Cost Paddlewheel Flow Meter

The FP5100-Series is accurate to ±0.2 fps, with repeatability at ±0.1 fps. This insertion sensor operates on a simple electromechanical principle.

Battery Powered Indicating Flow Meter For Rate or Total Flow

The FP2000-Series displays the rate of flow, total or both (depending on the model selected) on a 6-digit LCD display. Two AAA batteries power the unit for up to one year.

Stainless Steel Paddlewheel Flow Meter

The FP-5200 also features OMEGA's patented "open-cell" rotor, for increased linearity at 1% over the full dynamic range of 1.6 to 20 fps, with negligible head loss.

Adjustable Length Insertation Paddlewheel Flow Meter

The FP6500-Series features Ruby bearings and a non-drag pick-off that give these adjustable insertion flow sensors the widest flow range of any of the paddlewheel types.

PVDF Flow Monitoring System for Corrosive Fluids

For maintaining safe transport of highly corrosive acids, you can depend on OMEGA's all-PVDF FP5100-Series flow monitoring systems.

Flow Sensor with Visual Indication and Switch or Pulse Output

The FPR100-Series sensors are designed with a one-piece composite rotor, sturdy unibody construction, ceramic shafts, and superior sealing, to provide durability and economy.

Low Velocity Paddlewheel Flow Meter

The FP-5600 and FP8500A-Series low flow sensors are high resolution, low power devices ideal for measuring flow in piping systems with extremely low velocities.

All Metal Hot Tap Option Paddlewheel Flow Meter

The FP-2540-Series offer the added strength and corrosion resistance of stainless steel for applications requiring low velocity measurement.

Paddlewheel Flow & Temperature Meter

The FP7002-Series Paddlewheel Flow sensor/transmitter flow system provides a simple solution for applications requiring a remote flow temperature sensor.

Low Flow Polyproplene & TFE Liquid Flow Meters

The FPR300-Series body material is polypropylene, with transparent acrylic covers for visual flow indication. Polypropylene covers are available as an option.

General Purpose Paddlewheel Flow Meter

The FPB100 sensor is an industry standard and has the added functionality of various output options including flow switch, multi-functional pulse divider or 4 to 20 mA.

Low Flow Indicating Paddlewheel Flow Meter

The FTB300-Series of digital paddlewheel are an economical choice for low flow rate applications. They use Infra-red light beam technology. Available in 1/8 FNPT, 1/4 FNPT.


The SFI Series are manufactured of quality materials and safety tested to assure long, dependable service at economical prices. They feature a double window with a rotating impeller and removable window for easy service and replacement of wearing parts.

Fixed Length Inseration Paddlewheel Flow & Temperature Meter

The FP7001A paddlewheel flow and temperature sensor is ideal for accurate monitoring of industrial water flows, hard-to-handle corrosive solutions, and high purity fluids .

Mini PVDF Flow Sensor

The FP-5070 Mini-Flow sensor is ideal for precision low flow. The FP-5070 is available in four flow range configurations, covering a very wide range of flows

Plastic Paddlewheel Flow Meters With Optional RTD Sensor

Fluid through the FPB1400 causes the paddlewheel to spin. As the paddle magnets spin, electrical pulses are produced in which frequency is proportional to the flow rate.

Indicating Plastic Paddlewheel Flow Meter W/Alarms & Totalizers

FP1400-Series flowmeters have two programmable flow totalizers, low, high, or range flow and temperature alarm, two sets of optically isolated outputs, and flow pulse output.

MIDWEST Sight Flow Indicator

MIDWEST Sight Flow Indicator offer threaded process connections. Maintenance is simple with internal wipers. Economical.


The Series PFT Insertion Paddlewheel Flowmeters monitor liquid flow rates in pipes from 1-1/2 to 40". The unit outputs a frequency proportional pulsed or 4 to 20 mA output.

Paddlewheel Flow Meters

Paddlewheel Flow Meters are important devices used in a variety of industrial, commercial, and laboratory applications. These meters measure the flow rate of liquids and operate based on the principle of a rotating paddlewheel placed in the path of a fluid.

Omega Engineering boasts a wide range of paddlewheel flow meters that can handle a variety of environments – including holding up to corrosive fluids. These devices offer precision, accuracy, repeatability, and low power consumption.

The all-PVDF FP5100-Series flow monitoring systems are especially useful for maintaining safe transport of highly corrosive acids. The FP-5200 features Omega's patented "open-cell" rotor for increased linearity at 1% over the full dynamic range of 1.6 to 20 fps, with negligible head loss. Battery-powered indicating flow meters can display rate of flow, total or both on a 6-digit LCD display. For industrial water flows, hard-to-handle corrosive solutions, and high purity fluids, the FP7001A paddlewheel flow and temperature sensor is an ideal choice.
