SENSEZ Level Memory PW Water Level Observation Systems
Products Made in Japan
Manufacturer :SENSEZ
Model :Level Memory PW
Lightweight, compact and environmentally friendly long-term observation possible (Water level sensor for paddy field)
Features
- Immersion-type
- For paddy fields and irrigation channels
- 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.
- Lightweight, compact, and environmentally robust for high-accuracy measurement
- Exchangeable batteries enable long-term measurement.
- Ideal for water level observation for paddy fields and irrigation channels
