Portable underground water level meter

Breathable or non breathable, stainless steel or titanium alloy, 2MB or 4MB memory.

It is specially designed to accurately measure water level and temperature, and record data according to the mode selected by the user.

The instrument is powered by a built-in battery and can continuously record data for many years.

The data recording mode includes linear average, event triggering and logarithmic sampling.

NEMA 6p shell is adopted, which conforms to IP68 waterproof grade.

The battery can be replaced in the field and the cable can be loaded and unloaded quickly.

It can store 600000 data (including water level, temperature and time).

Water level range up to 210 meters, breathable water level or absolute reference pressure.

Air pressure recorder is optional for non breathable models to compensate for changes in atmospheric pressure.

High precision, the total error is ＋ 0.05% of the full range (the water level is higher than 3m).

RS-485 network connection;

Built in Surge Protector: 1.9 weight meter outer diameter, 316 stainless steel or titanium alloy optional.

Battery life up to 3 years, field replaceable; Firmware can be upgraded in the field.

Data monitoring software is used to set recording frequency, display table or graphic data,

atmospheric pressure correlation correction of absolute pressure data, download data,

obtain real-time data samples and set alarm prompts.

The upgrade software can be downloaded for free.
