Drum-type Gasmeters TG-Series (Wet-Type)

RITTER drum-type gas meters are universally applicable for measuring the volume of flowing gases and are particularly effective when measurements demand the highest precision.

The possibility of selecting the gas meter material from among 5 different excellent materials (polyvinyl chloride (PVC), polypropylene (PP), polyvinylide fluoride (PVDF), PE-el (polyethylene-electrically conductive) or 1.4571 (refined stainless steel) enables the user individually to meet measurement requirements even in case of highly aggressive gases.

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

The desired measurement range can be selected from among 9 magnitudes (types) extending as a whole from 0.1 ltr/h to 18,000 ltr/h at a gas temperature ranging from -50 to +120 °Celsius. The solidly manufactured casing of the standard meters is designed to withstand a maximum overpressure of 50 mbar (plastic casings) or 500 mbar (stainless steel casings); meters for higher pressure ranges up to 10 bars are available.
RITTER drum-type gas meters are universally applicable for measuring the volume of flowing gases and are particularly effective when measurements demand the highest precision.

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.

Ritter can also provide gas sampling bags in a range of sizes together with various valve options.
