This flowmeter is a fixed type ultrasonic flowmeter based on
transit-time measuring method. Thanks to micro-processor
based electronics, the flowmeter can be easily configured
from the keyboard to specific applications, the flowmeter is
suitable for liquid flow measurements for pipe size 50mm to
6000mm diameter.
The flowmeter is a compact and light-weight instrument
incorporating the latest electronics and high speed digital
signal processing technologies (32bit MPU), realizing high
performance and easy operation. This high performance
flowmeter is capable of realizing a simultaneous 2-path or
2-pipe system.
FEATURES
1. Compact and light-weight
This flowmeter is designed through use of the latest elec-
tronics and digital signal processing technologies.
2. Full variety of sensors
The flowmeter can be used with various types of sensors
applicable for small to large pipe (ø50 to ø6000mm) and
low to high fluid temperature (-40 to +200°C).
3. High accuracy
The flowmeter is designed for high accuracy (better than
±1.0% of rate) by dynamic correction of fully-developed
flow profile. Reynolds Number is calculated and a meter
factor (K) is automatically applied for best accuracy at all
flow velocities.
The adoption of new sound velocity measurement system
permits measurements of fluids of unknown sound veloc-
ity with slightly affecting from fluid temperature and pres-
sure.
4. Excellent resistance against aerated flow
Fuji' s unique ABM feature improves measurement reli-
ability for different flows like slurries, sludge, raw sewage
and bubble-contained flow (acceptable up to air bubbles
of 12% volume at 1m/s velocity).
5. Simultaneous 2-path or 2-pipe system
Average flow rate on 2 propagation paths can be mea-
sured simultaneously with less influence from changes in
time of flow profile. And also flow measurement in two
separate pipes with one FLH3 can be realized for calculat-
ing functions of flow.
6. Excellent performance and easy operation
Large LCD and function keys allow easy configuration and
trouble shooting.
– LCD with back light
– Easy mounting of sensor
– Trouble shooting
