DRUM-TYPE GAS METERS
RITTER drum-type gas meters (wet test) are universally used for measuring the volume of flowing gases and are particularly effective when measurements require the highest accuracy.
The ability to select the gas meter material from five different excellent materials: Polyvinyl Chloride (PVC), Polypropylene (PP), Polyvinyl Fluoride (PVDF), PE-el (electrically conductive polyethylene), or refined stainless steel 1.4571 (316 Ti) allows the user to individually meet measurement requirements even in the case of highly aggressive gases.
For rugged industrial applications, robust models with stainless steel housings and thermoplastic drums (four different materials) are available.
The desired measuring range can be selected from eight sizes (types) ranging from 1 L/h to 18,000 L/h at a gas temperature ranging from -10?C to +80?C. The robust housing of the standard meters is designed to withstand a maximum overpressure of 50 mbar (thermoplastic housing) or 500 mbar (stainless steel housing); meters for higher pressure ranges of up to 40 bar are available.
RITTER drum gas meters operate on the displacement principle. These meters contain a rotating measuring mechanism (measuring drum) inside a packing liquid (usually water or low-viscosity oil). The measuring drum measures the volume by periodically filling and emptying four rigid measuring chambers.
Meticulous production and calibration methods allow for a measurement accuracy of ?0.2% at a standard flow rate and approximately ?0.5% across the entire measuring range.
The main advantage and superiority of volumetric gas meters (such as drum gas meters) over other measuring principles, which determine gas volume using secondary measurable variables such as velocity, heat capacity, hot-wire resistance, or similar, is direct volume measurement. This means that the condition and composition of the gas have no influence on measurement accuracy.
Therefore, correction factors that take into account gas type, temperature, humidity, etc., are not necessary. It should be noted that with other non-volumetric measurements, the accuracy given for that measurement can only be achieved if the correction factors for the actual condition of the gas or gas mixture are accurately known.
