Advantages

  • Highest dosing accuracy by means of vacuum diaphragm pump Dosing of single samples from 15 - 250 ml (multiple dosing possible)l
  • event sampling can be performed parallel to the standard program
  • with the Multi Channel Transmitter wastewater flows can be monitored continuously and event sampling can be started directly in case of irregularities
  • the integrated logger allows the evaluation of historical measurement and sampling data. With the optional LTE modem, these can also be transferred wirelessly via e-mail, FTP and directly to the Ori Mcloud
  • the Atex certified design allows the use within the duct system in hazardous areas of zones 1 and 2

Logger

  • NEMO logs all relevant data, such as measured values, sampling dosages and further service data in the internal 8GB data memory
  • When using the ISM sensors, further characteristic data such as DLI (dynamic life), serial numbers...are stored


4G / LTE

  • The NEMO product range can be optionally supplemented with a 4G (LTE) modem
  • Atex certified for II 2G IIB T4 it can be used to communicate within Zone 1, directly from sewage shafts or other hazardous areas
  • Data can be transferred periodically or event-driven via e-mail, FTP or in parallel directly to the Ori Mcloud
  • Sampling can be started or operating states queried via SMS


RS 485 Modbus/RTU

all logged data such as:

  • Sensor readings
  • Sampling log data
  • Alarm values
  • Thermostatization characteristic values

can be read out via corresponding registers through RS 485 Modbus/RTU interface

Intelligent process sensors

Plug and Play connection of up to 4 digital ISM Mettler Toledo or EOG sensors to the NEMO transmitter in parallel possible.

With predictive maintenance and sensor diagnostics
The predictive maintenance features of the NEMO Transmitter provides diagnostic functions for the Mettler Toledo ISM sensors, such as a dynamic life indicator (DLI). This information reduces the need for maintenance as well as the risk of unplanned downtime due to unexpected sensor defects. You will be informed when maintenance or calibration of the ISM sensors is required.
