TideMaster Portable Tide Gauge For Marine

TideMaster Portable Tide Gauge For Marine


The TideMaster is a small, cost effective Water Level Recorder, specifically designed for applications where the user requires an accurate record of water height, but with the added option of meteorological data via a ultrasonic wind speed and direction sensor.

Suitable for use in fresh or salt water, the TideMaster can be deployed for up to 1 year, dependant on the sampling rate, with instrument set up and data retrieval via an optional display panel or using the PC software supplied. Alternatively, the system can be supplied with radio modules for real time data transmission.

TideMaster has been designed to provide an accurate, versatile and easily deployed tide gauge for use in short or long term survey operations with either pressure or radar sensor measurement. Data display panel, Bluetooth, SD card memory and weather sensor interface provide unrivalled functionality. Low power consumption and user selectable sampling regime allow for up to a year of autonomous operation. A number of Telemetry packages are available to extend the system’s capabilities to real time operations. TideMaster is compatible with a wide range of hydrographic software packages and tools.
