Kobold Instruments' BGN armored, variable-area flowmeter has an all-metal design and is available in stainless steel, PTFE-clad stainless steel or Hasteloy-C22 - ideal for difficult applications requiring high-pressure, high-temperature operation or low pressure loss. It's suited for water, most viscous liquids and compressed gases in line sizes up to 6 in. An analog output is standard for HART-based signals.
