Gas Meter Gas Purging Merk Ritter Bellows type Gas Meters BG Series

Bellows-type Gas Meters BG-Series (Dry-Type)

Application :
RITTER bellows-type gas meters are applicable for measuring the volume of flowing inert and dry gases and are particularly effective at high gas flows. Please note that gases containing aggressive components may reduce the life span of bellows-type gas meters, if the casing of the measuring unit (tinplate), the valve/control elements (polyamide) or the bellows (Perbunan) should be attacked.
The desired measurement range can be selected from among 6 magnitudes (types) extending together as a whole from 40 ltr/h to 160 m3/h at a gas temperature ranging from -20° to +50 °Celsius. The solidly soldered casing on the standard model is designed to withstand a maximum overpressure of 50 mbar (BG 40/100: 0.5 bar).

Equipment :
8-digit Totalizing Roller Counter
Gas Pipe Connection: Inch Thread
Large, One-needle Dial
Magnetic Coupling (between the measuring drum and counting mechanism)
Twin-Chamber Measuring Unit

Materials :
– Casing : BG 4 – BG 16: zinc-coated steel sheet (soldered) with outside also lacquered / BG 40 – BG 100: powder-coated steel sheet with outside also lacquered
– Measuring unit : tinplate
– Bellows (within measuring unit) : textile-reinforced Perbunan
– Rod linkage : BG 4: polyamide; all others: polyamide/brass
– Slide gate : Bakelite
