All-Metal Armored Variable Area Flowmeter and Totalizer Model BGF
Description
The KOBOLD BGF metal-armored variable area flowmeter is 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
flowmeter 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 flowmeter 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.
Special Advantages
●● Ideal for Difficult Operating Conditions
●● Can be Used for All Directions of Flow
●● A Large Spectrum of Wetted Materials
●● Magneto-resistive Signal Transmission
●● Special Design for High Pressure
and High Temperature Applications
