The measurement of RITTER drum type gas meters works on the principle of displacement. The gas meters contain a revolving measuring mechanism (measuring drum) within a packing liquid (usual: water or thin bodied oil). The measuring drum compulsorily measures volume by periodically filling and emptying four rigid measuring chambers.

The possibility of selecting the gas meter material from among 5 different excellent materials enables the user individually to meet measurement requirements even in case of highly aggressive gases:

• polyvinyl chloride (PVC)
• polypropylene (PP)
• polyvinylide fluoride (PVDF)
• PE-el (polyethylene electrically conductive)
• refined stainless steel 1.4571 (316L)

For rugged, industrial applications, robust models with a stainless steel casing and plastic drum (four different materials) are available.

The major advantage and the superiority of volumetric Gas Meters (like Drum type Gas Meters) over other measurement principles, which determine gas volume using secondary measurable variables such as speed, heat capacity, hot wire resistance or similar, is that the volume is directly measured. That means that the condition and the composition of the gas has no influence on the measurement accuracy.

Correcting factors which take into account gas type, temperature, humidity etc are therefore not necessary. It should be noted that with other, non volumetric measurement processes, the measurement accuracy given for that process can only be achieved if the correcting factors for the immediate condition of the gas are exactly known.

Specifications

• The desired measurement range can be selected from among 8 magnitudes (types)
• 1 ltr/h to 18,000 ltr/h at a gas temperature ranging from -10 to +80^oC.
• Maximum over pressure of 50 mbar (plastic casings) or 500 mbar (stainless steel casings); meters for higher pressure ranges up to 16 bars are available.
• Accuracy: + 0.2% at standard flow rate and approx. + 0.5% over the whole measuring range

Equipment

• 4-Chamber Measuring Drum
• Magnetic Coupling (between the measuring drum and counting mechanism)
• 8-digit Totalizing Roller Counter
• large, one-Needle dial
• Filling-level Indicator (for setting the Packing Liquid level)
• Manometer/Thermometer Supports
• Viton sealing
• Level; and Levelling Feet
