BK-G4
The G4 gas meter is a remarkably small, lightweight meter ideally suited to residential submetering applications. Despite its small size, the G4 meter is incredibly accurate and reliable when measuring either natural or LP gas. The G4 is classified as a 200 cubic foot per hour (cfh), non-temperature compensated gas meter with cyclometer register.

Description
The design consists of four measuring chambers separated by synthetic diaphragms. The chambers are filled and emptied periodically and the movement of the diaphragm is transferred via a gear to the crankshaft. This shaft moves the valves that measure the volumetric gas flow. Rotations of the gear are transferred via a magnetic coupling to the index, thus assuring proper sealing of the meter’s internal mechanisms. The BK-G4 register includes a reed pulse output for interfacing with remote (hard-wire, telephone, radio) reading and collection devices.
