Brief information 

RVG: Flange connection G16 - G400

RVG-ST: Standard thread connection G10 - G25

Operating Principle

Elster-Instromet RVG and RVG-ST rotary gas meters are volumemeasuring devices for gaseous media and operate according to the positive displacement principle.

They register the gas volume under operating conditions. In order to correct the measured volume to standard conditions, electronic volume correctors with various characteristics are available.

The actual measuring cell consists of two 8 shaped impellers, which build together with the housing 4 chambers per revolution, which are periodically fi lled and emptied.

The number of revolutions is proportional to the passed volume. The rotation is transferred to a mechanical index, which indicates this volume.

 

General: Rotary meters are characterized by high measuring range and compact dimensions.

Due to their measuring principle they do not require any straight inlet or outlet pipe section. Rotary meters have to be lubricated with oil. For easy access and control of the appropriate oil level the oil chambers on the front and the backside are connected to allow maintenance to be done from the front side only.

The double direction index allows adapting the meter to any fl ow direction. The RVG is available with the latest technology of the Absolute-ENCODER S1D, which enables the most reliable readout of a mechanical index.

The RVG-ST is the smallest meter line from G10 to G25. It has a threaded connection as standard. Optionally it is also available as fl ange version.

The index of the RVG-ST is located in the gas area, while the RVG uses index variants outside the gas area in atmospheric air driven by a magnetic coupler.

LF pulser E1 and PCM

Elster-Instromet RVG rotary meters are commonly equipped with 2 low-frequency (LF) pulse generators and an additional monitoring reed switch (PCM) for detection of line break or interferences caused by magnetic fi elds. These pulse generators are attachable and can be retrofi tted or changed without opening totalizer.

 

LF pulser IN-W11

As an option, it is possible to fit Elster-Instromet RVGs with the Wiegand sensor module IN-W11 instead of the LF pulser module IN-S1x. The IN-W11 is a low-frequency pulser with a defi nite pulse width > 50 ms, which is highly reliable and ensures there is no mechanical wear and tear.
