SENSEZ Level Memory MW2 Water Level Observation Systems

Products Made in Japan
Manufacturer :SENSEZ
Model :Level Memory MW2

Lightweight, compact and highly environmentally friendly long-term observation possible

Features

  1. Immersion-type
  • System consisting of an immersion-type water level meter and a 1-channel data logger. Data is transferred to a PC using a data collector.
  • Atmospheric correction is not required because atmospheric pressure is released via the vent filter of the waterproof casing housing the water level meter cable and logger.
  • Can be selected from a range of 2 m, 5m, 10m, 30 m, and 50 m.
  • Lightweight, compact, and environmentally robust for high-accuracy measurement
  • Exchangeable batteries enable long-term measurement.
  • Ideal for water level and volume research for small hydroelectric power plants
