Nemos 200+
IP68 GSM Datalogger
The NEMOS N200+ is a GSM-enabled, battery-powered data acquisition device designed for operation in manholes and flood-prone environments. In its basic configuration, it features four digital inputs suitable for flow meters and two analog inputs. Optionally, it can be equipped with a MODBUS RTU interface and one or two integrated pressure sensors with water hammer detection capabilities.
The Nemos N200+ incorporates the latest narrowband communication technologies, NB-IoT and CAT.M1, while maintaining the 2G standard. This allows the device to communicate with the most prevalent networks currently available (2G) and prepares it for the future development of NB-IoT/CAT.M1.
The Nemos N200+’s unique detachable antenna design offers the best features of an integrated antenna solutionārobust mechanical strength and IP68 protectionāwith the flexibility to remove the enclosure and install an external antenna where needed. The Bluetooth radio provides convenient local communication and diagnostics, allowing these tasks to be performed remotely from outside the enclosure or inspection chamber.

GENERAL INFORMATION
Detachable antenna
The innovative detachable antenna concept of the Nemos N200+ offers two configurations:
Integrated antenna: The datalogger and antenna form a solid, watertight unit. The half-wave dipole design offers excellent performance, exceeding 90%. External antenna: The detachable antenna housing provides access to a stainless steel SMA connector, thus allowing the installation of an external antenna.
The IP68 certificate of the Nemos N200+ has been validated for both configurations
Batteries and autonomy
The NEMOS N200+ is supplied with two battery capacities: one pack of 7.2V and 14AH or two packs for a total of 7.2V and 28AH. This is, respectively, double and quadruple the industry standard.
| Channels | Sampling freq. | Transmission freq. | Capacity | Battery estimate* |
|---|---|---|---|---|
| Flow rate & pressure | 5 minutes | 24 hours | Single pack | 10 years |
| Flow rate & pressure | 5 minutes | 1 hour | Double pack | 4 years |
| Flow rate & pressure (Transient detection mode) | 5 minutes | 24 hours | Single pack | 5 years |
Pressure
The NEMOS N200+ is the most advanced datalogger in its sector for pressure monitoring. This is due to its highly energy-efficient implementation, which enables continuous pressure measurement despite the limitations imposed by battery power.
Pressure monitoring is configurable in two modes:
Low power mode: Pressure is read every second. This generates maximum, minimum, and average statistics for each recording period. The impact on battery life is negligible.
Transient detection mode: Pressure is read between 8 and 128 times per second depending on the configuration and detected pressure gradient, recording pressure transients and water hammer. The high sampling rate of 128 Hz allows for high-fidelity capture of peak pressures.
