LoLOG Vista+

Robust Stand-Alone Data Logger with Display

The Lolog Vista is a particularly robust and economical data logger, available in versions with one or two measurement channels.

Fully waterproof, submersible and battery-powered, it is designed for portable use for various instrumentation needs: level, pressure, flow, events, counting...

As an option, an LCD screen can be integrated for immediate reading of the measurements during commissioning or inspection visits, without the need for a computer connection.


Like the compact model without a screen (Lolog 450), the Lolog Vista data logger is often used in temporary measurement campaigns for technical studies or performance checks, when a solution with telemetry is not required or possible.

It can also be considered for permanent installations thanks to its very high battery autonomy (several years) and its extended memory capacity (up to 1 million data readings), with periodic reading of the recorded time-stamped data.

Its portability, watertightness and flexibility for the types of signals connected make it ideal for many applications, including:

  • Water pressure monitoring on network points, fire hydrants, etc.
  • Verification of the operation of pressure control valves
  • Monitoring of reserve levels, water tables, rivers, sewerage networks etc.
  • Diagnosis of meters or flowmeters, mono and bidirectional counting
  • Quantification of requests, accounting of volumes and consumptions
  • Network sectorization studies and leakage flow measurements
  • Event detection and recording (overflows, equipment start-ups, etc.)
  • Precipitation measurement with rain gauge (rain, sleet, hail)
  • Calibration of hydraulic network models (availability of versions with 0.1% measurement accuracy)
  • Various combinations (e.g., Pressure+Flow, Level+Overflow)
  • Recording of various measurements from sensors and instruments with 4-20 mA output

A special version of the product is available for use with Hydreka's WinFluid software.
