±1% of rate over optimum flow range with proper straight-run installation
Wetted parts
316 stainless stem/adapter; PPS or PEEK sensor tip
Approvals
NSF/ANSI/CAN Standards 61 and 372
Product Family
Data Industrial SDI Series insert-style impeller flow sensors (stainless steel NSF)
Pipe Sizes
1-1/2…36 in. (38…914 mm) depending on stem length and tapping method
Flow Velocity
Optimum 1…20 ft/s (0.30…6 m/s); extended below 0.5 ft/s
Fits closed-pipe liquid flow where you need a Badger Meter SDI insertion impeller sensor—0.3–20 ft/s velocity with ±1% of rate accuracy over the optimum band.
Key advantages
- Velocity — 0.3–20 ft/s (0.09–6.1 m/s); optimum 1–20 ft/s
- Accuracy — ±1% of rate over optimum; custom wet cal to ±0.5% class
- Repeatability — ±0.5%
- Style — Insertion impeller for liquids in closed pipe
- Install rule of thumb — 10 diameters up / 5 down of disturbances
Typical applications
- HVAC chilled/hot water.
- Irrigation / water distribution.
- Industrial liquid process lines.
Selection guide
- Pipe size / insertion depth
- Output / transmitter pairing
- Wetted materials
- Wet calibration — Standard vs custom
Common mistakes
- Installing with insufficient straight run.
- Wrong insertion depth / shaft orientation.
- Using on aerated or dirty slurry without screening.
When to RFQ / what to tell us
- Pipe size, fluid, velocity.
- Output type, quantity, ship-to.
