Aqualog Diana


AQUALOG DIANA the battery-powered data logger to permanently monitor:

  • Water Hammers
  • Pressure
  • Flow

This data logger allows pressure transients to be permanently acquired and recorded.
Equipped with geolocation and synchronisation with integrated GPS.

To monitor pressure, levels and flow in areas that are difficult to access and where electricity is not available. The product has, in fact, been designed to require minimal energy.

  • Low power, 2 years autonomy.
  • In extended mode 4 years IP68 protection
  • Discovery mode: of “Water Hammers” recorded as frames and of high frequency audits up to 48 hours
  • Data acquisition and transmission from the RTCP (Real Time Critical Point)
  • 4G cloud connection
  • Records stored of pressure, flow and level


  • Pressure/level: 1 pressure/level input with piezoresistive sensor
  • Flow: 1 Flow Meter input
