3. Important information
3.1 Main hazards
WARNING!
Pressurized flammable gas flows through
the Flowbody of the FLC-UFL series ultrasonic
gas flowmeter. Do not remove any transducers
or parts from the flowbody whilst the flowmeter
is under pressure. Flammable gas can escape
and parts may blow out.
3.2 Intended use
The FLS-UFL series ultrasonic gas flowmeter primary use
is to measure the volume flow rate and gas velocity of gases
in pipelines.
Optionally the FLC-UFL series can convert the volume
flow at measuring conditions to base conditions as well as
registering data on meter readings, diagnostics and other
data.
3.3 Identification
Each FLC-UFL series flowmeter has two nameplates for
identification, one on the SPU and one on the flowbody.
Refer to chapter 4.2.3 for detailed information about the
nameplates and identification.
3.4 Operation in explosive atmospheres
The FLC-UFL series flowmeters are suitable for use in
potentially explosive atmospheres. Refer to the Safety
instructions [1] (
81500907 FLC-UFL Series Safety
Instructions
) for detailed information about this.

3.5 Restrictions for use
The FLC-UFL series flowmeters are suitable for use
in pressurized lines within the design conditions specified
on the flowmeter nameplate.
3.6 Cleaning
Only clean the FLC-UFL series ultrasonic flowmeter with a
damp cloth. Do not use solvents for cleaning.
3.7 User responsibility
The user should read and understand the operating
instructions prior to putting the FLC-UFL series ultrasonic
flowmeter in use. All safety information should be observed.
