The TGR-1050 HT is a purpose designed recording tide
gauge for long term monitoring of tidal activity in
unattended locations. The instrument may store up to
2,400,000 readings on 8MB memory and has battery
capacity to run unattended for five years.
It may be connected by direct RS232 or RS485 line,
VHF/UHF radio telemetry or CDMA/GSM modem to
the office or base station. It may also be programmed
to operate autonomously, and it is able to run in this
way for up to five years on internal batteries.
Tide measurement is achieved by averaging pressure
data, sampled at a rate of 4Hz. The sample period and
the length of the averaging burst are fully
programmable. |
