Gas Meter - Milligascounter - Ritter by Ross Brown Sales

Supplier: Ross Brown Sales

Able to record and measure flow rates from 1 ml/h to 1 ltr/h, the Ritter Milligascounter is produced for low quantities of gas with extremely miniscule flow rates.


It is suitable for measuring all inert and slightly aggressive gases, in particular those encountered in biogastechnology or in leak rate detection.


  • Minimum flow rate 1 ml/h
  • Maximum flow rate 1 ltr/h
  • Resolution 3 ml
  • Accuracy ±3  per cent of reading across full flow rate range; in combination with "Rigamo" software better than ±1 pre cent
  • Use with inert and medium corrosive gases (biogas)
  • Materials: Plexiglas (PMMA), PVDF, PVC (red)
  • digital counter with programmed calibration factor
  • battery operated; battery life-time 3-4 years
  • low-maintenance

The patented MilliGascounter1 is designed for the measurement of small amounts of gas with ultra-low flow rates. It is suitable for measuring all inert and slightly aggressive gases, in particular those encountered in biogas technology or in leak rate detection.


The minimum flow rate is theoretically 0 ltr/h, as there are no mechanical limitations on the MilliGascounter which would restrict the minimum flow.

However, at such micro flow rates, there are influences external to the MilliGascounter which become evident (tightness of the tube connection, permeability of the gas tubing). The minimum flow rate has therefore been defined as 1 ml/h. The maximum flow rate is 1.0 ltr/h.

Through a special manufacturing technique and high precision calibration, a Measurement Accuracy of ±3% has been achieved.The volume is measured with a Resolution of 1 ml.

Gas Pressure and Temperature:

The MGC has a maximum gas inlet pressure of 100 mbar (1.5 psi). The minimum differential pressure is 5 mbar (0.073 psi).

The MGC withstands constant use temperatures ranging from +10 to +60 °C (PMMA) (+50 to +140 °F), (+10 to +40°C for PVC, +10 to +80°C for PVDF)
Data Presentation

The volume of the measured gas is displayed on an electronic counter / display located on the top of the MGC casing.

Additionally a reed contact can be used as a signal output.
Data Acquisition with PC

For data acquisition of gas volume and flow rate the Windows software RIGAMO is available. The data of up to 24 Ritter gas meters can be transmitted to the USB port of a PC.
