How it works

Designed to fit existing routines — not disrupt them.

Step 01

Install in seconds.

Two suction cups. No plumbing, no wiring, no IT. Mounts on virtually any commercial urinal in under a minute.

Step 02

Test runs automatically.

Every time the urinal is used, InFlow runs a urine spectral analysis — flush to result in five seconds. No samples. No behavior change. No staff time.

Step 03

Red, yellow, or green.

The whole urinal lights up with an objective result — visible to your team and staff. Hydration becomes a culture, not a clipboard.

Why Intake

The only system your team actually needs.

Every other hydration tool depends on individual behavior — wearing the patch, providing the sample, doing the weigh-in. InFlow doesn't.

The science

Optical urinalysis.
Validated against the gold standard.

Peer-reviewed in Frontiers in Sports & Active Living. Performance interchangeable with handheld digital refractometers — without samples, staff time, or burden on your team.

How it works

Calibrated to urine specific gravity (USG) — the same standard your staff already uses.

  • Green   ·   USG < 1.012 Hydrated. Cleared for activity.
  • Yellow   ·   USG 1.012 – 1.025 Mild dehydration. Pre-activity hydration recommended.
  • Red   ·   USG > 1.025 Significantly dehydrated. Intervention indicated.

Validated as interchangeable with handheld digital refractometry — the clinical gold standard for hydration assessment.
