Tide Monitor
from Falmouth Scientific

Tide Monitoring System is a complete tide monitoring system for moorings and other long-duration fixed-site deployments. The pressure module is a precision strain-gauge pressure sensor for measuring water level; barometric pressure compensation is provided by a sensor mounted in the system’s surface enclosure, which also incorporates rechargeable battery and system communications. A 20-meter cable connects the underwater and surface enclosure. Non-corroding materials are used to ensure long sensor life with minimal maintenance. An optional solar charger allows for long-term, unattended operation.

Data is recorded in the system’s 256MB internal memory and can be output locally in real-time via RS-232 (optional RS-485) or reported remotely via RF (radio, cell) or satellite telemetry.


  • High Accuracy tide data - ±2.7 cm over the range of -2 to 30°C provided by: Precision pressure transducer, Surface barometric pressure. transducer, Correction for local salinity & gravity via user defined inputs.
  • Pre-configured for NOS Standard deviation (per NOAA CO-OPS standard).
  • On-board data logging and real-time output provide data where/when you need it.
  • Telemetry options allow for remote reporting of tide data.
  • Low-power operation and rechargeable batteries allow for long-term unattended operation.
  • Surface barometer maintains accuracy with lower maintenance than vented cable systems.
  • PUCK v1.3 protocol-compliant for “plug-andwork” ease of system configuration.
