Rotary Gas meters РЛ are designed to measure the volume flow rate natural and other non aggressive gases during the commercial metering of gas consumption facilities.
Gas meters maintainable, work with untreated gases and do not need additional mounting systems.
The service life of the meters, taking into account maintenance, is not less than 20 years.
The mode of operation can be both continuous and intermittent.
Counting mechanism capacity is 99999,999 m3.
Least division value of counting mechanism is 0,001 m3.
