Description

DESCRIPTION AND FUNCTIONING 

The MicroHYD3 monitoring and alarm stations had been developed to measure mainly the data becoming from hydrometric level sensors and for generate SMS messages when an overcome of pre-alarm and alarm thresholds occurs.  Furthermore when the alarm happens, the station can increase the number of data memorizations and transmissions up to a rate of 5 minutes; in this way it’s possible analyzing with greater resolution a flood phenomenon. As soon the alarms subside, the data memorization  and transmission resume the normal rate of operating

Furthermore MicroHYD3 can manage 2 pre-alarm and alarm relais to activate external devices for local alert (in this case mains 220Vac is needed)  

 

MAIN FEATURES

All working logic is managed from Geoves MicroHYD3 datalogger which is able to display, acquire, save and transmit the data via GPRS. Besides MicroHYD3 has three multifunction buttons that allow to setup on site the following hydrometric parameters: different kind of hydrometer (sonic, radar, piezometric, bubble air, …); engineering full scale;  calibration offset to get the measure a.s.l. (above sea level up to 9999,01m); distance between the no contact sensor and the minimum detectable level; pre-alarm and alarm thresholds. 

Furthermore the MicroHYD3 datalogger can interface also meteorological sensors (eg. thermohygrometer, rain gauge) or other measures with analog output.

MicroHYD3 stations can be equipe by several accessories for the installation of the hydrometer and the datalogger on bridges, piers and gangways, sinks, reservoirs, wharfs, channels, rivers, etc… Finally, thanks to a very low power consumption (few mAs), it’s possible supply the datalogger from a little photovoltaic panel and install the station everywhere even if the site is not reached from mains 220Vac (eg. high mountain or open field)

 

ADVANTAGES

  • Possibility to manage n.2 hydrometric measurement simultaneously
  • Possibility to set and calibrate the hydrometric measurement on site
  • Remote alarm sending via SMS and locally via pre-alarm and alarm relays for the control of external actuators (sirens, traffic lights, ...)
  • Data in standard text format (CSV format) compatible with Excel, database and with the most common software available on the market.
  • No connection charges (with GPRS wireless transmission and photovoltaic panel power supply)
  • Data accessible on the web from any device connected to the Internet (PC, smartphone, etc.) without the need to install any software
