MilliGascounter
General
Application:
The patented MilliGascounter 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.
Measurement Principle:
Please refer to the sub menu “Measurement principle.
Measuring-Range:
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.
Accuracy:
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 & 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.
