Supplier Honeywell BK-G4 Diaphragm Gas Meter
WWW.DITRIBUTORALATINDUSTRI.COM | Supplier Honeywell BK-G4 Diaphragm Gas Meter The Honeywell BK-G4 Diaphragm Gas Meter (formerly marketed under the Elster brand) is a high-precision residential and commercial gas meter designed for measuring natural gas, LPG, propane, butane, air, and other non-corrosive gases. The meter utilizes the proven positive displacement diaphragm principle to deliver reliable, accurate, and long-term gas consumption measurement for domestic, sub-metering, and light commercial applications.
Supplier Honeywell BK-G4 Diaphragm Gas Meter
The BK-G4 incorporates decades of Honeywell gas metering technology, featuring a compact, lightweight, and corrosion-resistant design. Its high-quality synthetic diaphragms and patented K-System valve mechanism ensure excellent measuring accuracy, low pressure loss, quiet operation, and long service life with minimal maintenance requirements.
The operating principle is based on four measuring chambers separated by durable synthetic diaphragms. As gas flows through the meter, the chambers are alternately filled and emptied, causing the diaphragms to move. This movement is transferred through a gear mechanism and magnetic coupling to the mechanical totalizer, allowing precise volumetric measurement while maintaining a completely sealed measuring system.
The BK-G4 meter is widely used in residential buildings, apartments, commercial establishments, industrial kitchens, and utility sub-metering systems. Optional pulse output modules enable remote reading, AMR/AMI integration, M-Bus communication, and connection to smart gas monitoring systems without affecting calibration or interrupting gas supply.
