2 Overview PFT - Paddlewheel Flow Transmitter IPFS - Paddle Flow Sensor PDWS - Paddle Flow Sensor DFMT/DFMT2 - Digital Paddle Flow Transmitter

3 Operation Principle Paddlewheel Flow Sensors Minimally invasive monitoring of fluid velocity in industrial pipes Cost effective in comparison to other technologies

4 PFT - Introduction Paddlewheel transmitter Inductive rotor sensing, no magnets Good for magnetic materials

5 PFT - Specifications Adjustable from 1-1/2 to 40” (38 to 1016 mm) pipes 1.2 to 25 ft/s (0.37 to 7.62 m/s) Linearity ±1% full range Repeatability ±0.5% full range NEMA 6P (IP69)

6 PFT - Features One unit adjustable for range of pipe sizes 1-1/2 to 40” (76 to 1016 mm) Pulse or 4-20 mA output signal In one unit with no need for converter Brass or stainless body, variety of o-rings Low friction bearings

7 IPFS - Introduction Adjustable insertion paddlewheel transmitter Hall Effect sensor with pulse signal output Good for low flow

8 IPFS - Specifications Adjustable between 3 to 40” (76 to 1016 mm) pipes 0.3 to 30 ft/s (0.09 to 9.14 m/s) Accuracy ±1.5% full range NEMA 4X (IP66)

9 IPFS - Features Adjustable for range of pipe sizes Brass, PVC, or stainless Hot tap option (brass or stainless) Use with Series SDF fittings Optional bi-directional sensor

10 SDF Fittings Use with PFT and IPFS sensors Brass or iron, 3 to 24” (76 to 609 mm) pipe size

11 PDWS - Introduction Fixed insertion paddlewheel transmitter Hall Effect sensor with pulse signal output Good for low flow

12 PDWS - Specifications Pipe sizes ½ to 8” (12.7 to 203 mm) 0.3 to 30 ft/s (0.09 to 9.14 m/s) Accuracy ±1.5% full range NEMA 4X (IP66)

13 PDWS - Features Brass, stainless, PVC, or polypropylene body Use with Series PWF fittings and tees High pressure options Immersion options

14 PWF - Fittings Use with PDWS sensor Bronze, PVC, SS, and steel ½ to 8” pipes (12.7 to 203 mm)

15 DFMT & DFMT2 - Introduction Digital paddlewheel sensor Hall Effect sensor with analog or pulse output Good for low flow DFMT DFMT2

16 DFMT & DFMT2 - Specifications Sizes from 3/8 to 2” NPT ( 9.5 to 51 mm) Measures flow from 0.5 to 180 GPM (0.1 to 40.0 m 3 /h) Accuracy ±1.5% full range IP65 rating Optional RS485 communications DFMT DFMT2

17 DFMT & DFMT2 - Features Measures instantaneous and total flow Resettable totalizer User selectable 4-20mA or pulsed output Easy to use push buttons for programming Password Protection DFMT DFMT2

18 BAT Transmitter Blind Analog Transmitter Use with IPFS and PDWS Converts pulse to 4-20mA Meter or wall mount

19 RTI Transmitter Rate/Total Indicator Use with IPFS and PDWS Converts pulse to 4-20mA Meter, panel, or wall mount

20 PWD Pulse Divider Pulse Divider Use with any pulse output transmitter Pace electronic pumps

21 Applications Irrigation Ground water remediation Cooling systems Pump flow proving Chemical Proportioning Reverse Osmosis

22 Irrigation Monitor water flow rate for pivot irrigation systems and drip irrigation systems Ensure proper water transfer

23 Groundwater Remediation Monitor flow rate of water usage from water source for the purpose of cleaning water source

24 Cooling Systems Monitor water flow in and out of cooling system Use for obtaining BTU usage and monitoring efficiency with BAS system

25 Chemical Proportioning Pump proving Continuous monitoring of chemical usage for ideal chemical proportioning or dosing

26 Reverse Osmosis Monitor water flow in and out of water filtration system Determine amount of water being processed
