Tide Gauges: Accurate, Reliable, and Easy to Install

Our tide gauges mount easily on piers, pilings, bulkheads, bridges, marinas, and docks. Choose from two powerful sensor options:

Patented Tilt Sensor
Installed under a gangway between a fixed pier and a floating dock, this sensor measures water levels through the angle of movement — ideal for tidal areas or lakes.

Ultrasonic Sensor System
Uses two independent ultrasonic sensors in one gauge — minimizing false readings and increasing reliability through redundancy. Works in tidal and non‑tidal environments for flood monitoring.

Every system is engineered for easy installation and low‑maintenance service in demanding environments. All include mounting hardware, are solar‑powered, and connect via cellular network to our Tide Alerts™ Web App.

Your Personal Tide Station — Anywhere, Anytime

The free Tide Alerts™ Web App brings live water‑level data and NOAA‑technique‑based tidal forecasts right to your fingertips. Accessible from any smartphone, tablet, or computer, it provides a complete, real‑time picture of local conditions.

Core Features:
-Real-time tide and/or flood levels updated from your installed gauge
-Monthly tide calendars with high and low tide events, including precise tide heights
-Tide forecasts generated from actual measured data—ideal for bays, estuaries, and areas without public forecasts
-Wind surge and flood monitoring to anticipate sudden water level changes affecting boating, property safety, or infrastructure

Enhanced Capabilities:
-Calendar sync — Export tide events directly to your personal calendar (Google, Outlook, iCal)
-Threshold tracking — Highlight times when water is too low for safe navigation, too high for bridge clearance, or reaching flood‑risk levels

Coming Soon:
-Custom alerts for user-defined tide or flood thresholds
-Automatic calendar generation based on your preferences and thresholds

Whether you're a boater, dock owner, harbormaster, researcher, emergency management professional, or inland flood‑prone property owner, Tide Alerts™ gives you the information you need to plan confidently and stay safe.

Unique Real‑Time + Forecast Capability

We’re the only provider combining real‑time water level measurements with local forecasts based on those measurements, plus a calendar of future events. This can help you anticipate critical conditions — from flooded roads to water too shallow for safe passage.

The TideLine™ Display reimagines the traditional tide staff for the 21st century. It features a 6-foot illuminated light strip set into a 4-inch wide wooden plank, with subtle level markings for depth for a clean, classic look.

Powered by data from either our Tide Alerts™ system or nearby NOAA tide stations, the TideLine™ provides real-time, at-a-glance information:

• Current tide height
  
• Direction (rising or falling)
  
• The next high or low tide level
• Alert levels for shallow water or low bridges

It’s a beautiful and functional addition to marinas, public docks, yacht clubs, or waterfront homes or restaurants—delivering real utility with a modern aesthetic that draws attention and starts conversations. (coming soon)
