From May 2015 on the mechanical flow meters series, BGF shipped with new and optimized indicator housing.
The new aluminum indicator housing is made of high-performance aluminum and is safely protected from corrosion or weather influences through a special anodizing as well as highly resistant paint finish.
The enclosure surfaces are rounded, the radius is optimized, and protect very effective that splash or other corrosives from the process environment will collect on or at the enclosure. The indicator housing inside has been optimized and therefore turned out to be flatter than it´s predecessor.
The proven technology of the sensor as well as from the sensor transmission has not been modified and will, therefore, be available unchanged with reliability and high robustness.
Flow metering of liquids and gases in pipelines.
Indication of momentary volume- or mass flow per time unit.
Applications: chemical-, petrochemical-, oil- and gas industry
Especially suitable for its robust design for processes under difficult and harsh conditions
- Horizontal mounting possible, therefore, to be used for all flow directions
- Clear 90 ° scale
- Linear characteristic by optimized float shape
- High-temperature versions up to 350 ° C
- High-pressure versions up to 600 bar
