Software – RIGAMO



  • Short Specification 1
  • Short Specification 2
  • Short specification 3


  • Unified Windows® software for measurement data acquisition from RITTER products
  • Support for multi-core processors
  • Windows® software for data acquisition of gas volume and flow rate from up to 18 RITTER Gas Meters to a PC USB port
  • Graphical and tabular display of measurement data in real-time
  • Normalization of measurement data by compensation of:
    • temperature
    • pressure
    • humidity
  • Storage of measurement data in both SD card (built into Signal Interface Module »SIM«) and PC
  • Data Acquisition even during failure of mains power supply
  • Export of stored data to Microsoft Excel® spreadsheet

Please note: »RIGAMO« can only started once at a time on a single PC.

No support of bi-directional recognition of the measuring drum rotation with Pulse Generator V4.01

The Signal Input Module »SIM« required for data acquisition is not approved for use in ex-proof areas!


Measurement of Gas Volume

  • Data acquisition of gas volume and flow rate from up to 18 RITTER Gas Meters
  • Measurement of gas temperature for recalculation to norm temperature (normalization)
    Please note: With the current version of the Signal Interface Module »SIM« only a single temperature probe can be connected to one »SIM« unit.
  • Measurement of atmospheric pressure for recalculation to norm pressure (normalization)
  • Compensation of humidity
  • Automatic correction of measurement data on the basis of the individual calibration curve: »Dynamic Correction of Measurement Error« (MilliGascounter only)


Operation with Biogas Batch Fermentation System »BBFS«

  • Temperature Control of Heating Oven
  • Speed Control of stirring units of fermentation bottle incl. interval mode
  • Real-time status of CO2 absorption for up to 18 CO2 absorption bottles (with optional accessory »CO2 Absorption System« of Biogas Batch Fermentation System »BBFS«):
  • Display of current CO2 absorption capacity for each absorption bottle
  • Display of remaining CO2 absorption for each absorption bottle
  • Alarm function for each absorption bottle if CO2 absorption capacity falls below a freely selectable level

System Requirements

  • Gas meter with built-in pulse generator (MilliGascounter standard)
  • Signal Interface Module »SIM« (option)
  • Operating system: Windows® 7 / 8 / 10 / 11
  • Microsoft Excel® 2003 or newer for data export
  • Recommended processor performance: ≥2 GHz
  • Random access memory (RAM): ≥4 GB
  • 1 available USB port
  • Monitor 17’’ or larger (optimised for monitor resolutions of 1280×1024 pixels or higher)
