Better flow, better culvert performance.
The Hydro-Bell culvert inlet device delivers a significant flow improvement over most culvert inlet shapes when operating under inlet control conditions. Ideal for many flood-prone culverts, Hydro-Bell connects to a female Snap-Tite end, providing a larger, wider intake at the culvert entrance. Bell-shaped chambers inside the pipe further increase throughput by reducing the effect of turbulent eddies as rushing water flows past.
Hydro-Bell innovation: new materials and design.
Hydro-Bell is the first inlet device introduced in recent years that uses newer materials to capitalize on the effects of culvert fluid dynamics. This innovative design makes it possible to maximize the hydraulic efficiency (and/or reduce head loss) of a relined culvert.
Why use Hydro-Bell?
Connected to the inlet end of the culvert liner, Hydro-Bell is designed specifically to improve overall system performance:
- An average flow increase of 30% compared to plain-end headwalls under inlet control conditions
- As head pressure increases, the Snap-Tite Hydro-Bell system flow rate increases
- Entrance loss coefficient (Ke) of approximately 0.2 for inlet control conditions
- No special training or tools required to install
