AQUA LOGGER HS

Reference AQUA LOGGER HS

Condition: New

Aqua Logger HS is used with a submersible pressure transmitter placed in the bottom of a water tank or watercourse. It is recommended for locations with a slight horizontal movement of the measured liquid.
The station is powered by a battery AGM 12V 35 Ah. This power supply allows the continuous work of the station with a data sampling of 10 minutes and an online update every 1 hour for at least 5 years.

OVERVIEW
SPECIFICATIONS

The Aqua Logger HS measuring station is a device dedicated to monitor the water level in a natural environment and in changing climatic conditions. The measurement is made with the use of a hydrostatic probe calibrated with the data logger. The water level is measured by calculating the hydrostatic pressure of the liquid column in the probe placed at the bottom of a water tank. The measured data is sent to the data server through GSM. In general, the station is powered by a 12V 35Ah AGM battery.
In most operating modes, this application is ready to run for several years without charging or replacing the battery. For example, if the measurement is made every 10 minutes and the data is updated every 60 minutes, the station works for a minimum of 5 years. A PV panel of 3W additionally continuous measurements in all possible data sampling settings and GSM transmission intervals.
The ultra low power consumption of the station marks it among others used to measure the water level.
A set of batteries provides a long working time that excludes other than the standard maintenance of the station. Compared with red solutions, Aqua Logger HS generates installation costs that minors
Full online access to the date of the measurement and transmission intervals, as well as the wide range of adjustable email and text alerts, allows for campaigns of professional and economic measures. Aqua Logger HS is recommended as a reliable and easy-to-install alternative to standard water level stations that operate at red or use large photovoltaic panels.
