Today we’re going to take a closer look at the Elster RABO Rotary Gas Meter….
RABO Rotary Gas Meter:
The RABO is suitable for measuring natural gas and various non-corrosive gases, rotary meters are characterized by their compact design, high measuring ranges and high accuracy.
RABO Operating principle:
Rotary gas meters are volume-measuring devices for gaseous media which operate according to the positive displacement principle. Due to their volumetric measuring principle,their functioning is not influenced by the installation and they are therefore ideal for compact measuring systems without an inlet section. They record the gas volume under operating conditions and are approved for custody transfer applications. Electronic volume conversion devices can be used in order to convert the volume.
RABO Measurement procedure:
Two rotating impellers which look like a figure of eight (8) when viewed in cross-section are mounted in a single housing with one inlet and one outlet. The two impellers are coupled together using synchronizing gears. When gas flows, the impellers rotate without touching one another and propel a gas volume to the outlet which is defined by the cyclic volume. One rotation of the system thus corresponds to a defined gas volume. The revolutions of the impellers are transferred to the mechanical index via a reducing gear and a magnetic coupler. The rotary gas meter is adjusted using a pair of gears in the index.
