The tidal telegraph is a digital processing of tidal level data collected in real time, such as swell suppression and intelligent screening, and convert the data to tide level information and send it out as a broadcast. The system can overcome the human error of artificial newspapers. It is widely used in port terminals and port dredging projects, and can also be used in hydrological observation.

The tidal telemetry instrument produced by our company adopts digital transmission technology, with the features of narrow occupied frequency band, strong anti-interference ability, good stability, low power consumption, directly powered by solar power, good swell suppression, automatic intelligent screening, simple maintenance, no need for staff. It can be used under unattended and no AC power (using solar power), especially in a specific water area, where telegraphs are installed at different locations. Multiple tide receivers can receive tide level data for more details. Record hydrological data for the waters. The system is equipped with an embedded data logger to continuously record hydrological data unattended and provides hydrological data for research and related organizations.
