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.
