Suitable Applications — Truflo TK3B
The TK3B is best suited for industrial/process installations that benefit from a 316 stainless steel meter body, rugged environmental protection, and battery-powered operation with local flow and total indication—especially where long life and wear resistance are critical.
- Industrial process lines requiring 316 SS wetted construction
- Chemical transfer and distribution where metal-body durability is preferred
- Skid-mounted systems needing battery-powered installation convenience
- Water/wastewater treatment and industrial utility water monitoring
- OEM equipment requiring pre-programmed flow sensing with local indication
- Applications needing IP66 / NEMA 4X protection (washdown/outdoor environments)
- Systems needing connection flexibility (including sanitary or ANSI flange options, consult factory)
