PUMPA Level Meter SW2+S3, probe with 15 m cable, measuring range 0–10 m, ON-LINE version

The Pumpa SW2 level meter is a device for measuring the water level in boreholes, dug wells, and tanks. Depending on the probe used, the level meter can measure levels up to 100 m >with a resolution from 0.1 m.

The level meter consists of a probe and a control unit. Based on data obtained from the hydrostatic probe, the unit displays the height of the water column above the probe. Measurement may be affected by current atmospheric pressure; however, the deviation caused by atmospheric pressure changes is at most ±0.3 m from the actual water level.

Advantages

• Easy installation and operation – after proper calibration and installation, anyone can operate the device.
• All in one package – level meters are supplied with complete accessories and all necessary installation materials.
• Wide range of probes S1–S4 – you can easily choose according to your needs.
• Instant data overview – after entering the serial number into the web application, all key information is immediately displayed – current air temperature (for freezing risk), daily and monthly maxima, minima and averages including clear graphs.
• Data export for advanced analysis – advanced users can easily export the complete database of measured data for further processing and detailed analysis.
• The unit is powered by a 12V supply. With the included POE adapter, the unit can also be powered remotely via a data cable.
• The electronic components are protected from mechanical damage by a durable plastic box measuring 126 mm x 55 mm x 176 mm (W x D x H).
• Application:

S1 – standard boreholes with water levels up to 40 m.
S2 – standard boreholes with water levels up to 70 m.
S3 – dug wells, pits, retention tanks with water levels up to 10 m.
S4 – boreholes with water levels up to 100 m.

The SW2 units include a temperature sensor on a 2 m cable. The sensor is used to measure ambient temperature or, using a sleeve, water temperature in pipelines (e.g., for geothermal boreholes). These sensors are paired with a specific unit.
