Viable for difficult applications requiring high pressure, high temperature, or low pressure loss, the BGN flowmeter sports an all-metal, armored design. It is available in stainless steel, PTFE-clad stainless steel, or Hastelloy C22. In a standard configuration, it is purely a mechanical meter suited for water, most viscous liquids, and compressed gases in line sizes up to 6 inches. Electronic limit switches and/or an analog flow transmitter may be added and an 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.
