2 Application according to designation, general safety instructions
2.1
Range of application, application according to designation
The thermal mass flowmeter FMT400-VTS/-VTCS is designed for flow rate measurements of compressed air,
nitrogen and biogas. It is only suitable to be mounted:
• as insertion sensor in a pipe component in pipes of nominal widths from 1 ... 3",
• via weld-on adapter directly in pipes with nominal widths up from DN 100 ... DN 250 (4 ... 10").
• The standard process temperature range is between -25
DANGER
!
• The device is not certified for use in hazardous areas
• Modification of construction details at the device by the user are not permitted.
Any other use is considered improper.
