Description
The Kobold BGF Series Variable Area Flow Meters are ideal for difficult applications requiring high pressure, high temperature operation or low pressure loss. Its all-metal, armored design is available in stainless steel or PTFE-clad stainless steel. This flow meter is unique in that its design employs a guided float and spring return mechanism that allows the BGF to be installed into both horizontal and vertical pipes. In standard configuration, the flow meter is a purely mechanical meter suited for water and compressed gases in line sizes up to 3 inches. Electronic limit switches and/or an analog flow transmitter may be added if desired. Analog output is supplied standard with HART protocol. Profibus-PA is also available as an option. Available switches and analog outputs include those that operate via intrinsically safe methods of protection and may be used in hazardous areas where intrinsically safe installations are permitted. Foundation Fieldbus is also available as an option. Custom designs for high pressure operation, special fittings and special materials of construction are available upon request.
