[email protected]F-4300 Series Clamp-on Ultrasonic Flow Meter Manual 06/17 - 2056-2 / 37515 Page 6
1.4 STANDARD FEATURES AND SPECIFICATIONS
• Wall-mounted NEMA 4X polycarbonate enclosure with backlit alphanumeric user interface/display
• One internally powered electrically isolated 4-20 mA analog output for ow rate or ow velocity.
• Two scalable electrically isolated dry contact pulse output for totalizing ow, indicating ow
direction or ow alarm.
GENERAL SPECIFICATIONS
ACCURACY
± 1.0% of reading from 1 to 20 ft/sec
± 0.01 ft/s for velocities below 1 ft/sec
OVERALL FLOW RANGE
0.1 to 20 ft/sec
SENSING METHOD
Clamp-on ultrasonic, differential transit time
method indirect or reect mode
PIPE SIZE RANGE
2” through 24” nominal diameter
PROGRAMMING
Factory programmed for specic application
MEMORY
Non-volatile memory retains all program
parameters and totalized values in the event of
power loss.
DISPLAY
White, backlit alphanumeric display shows:
5-digit ow rate with oating decimal, 14-digit
totalizer, pulse output status, operating status,
and provides eld conguration.
Displays total ow, ow rate, ow velocity,
signal strength, ow direction, alarm
conditions, relay status & logger status
Rate display range: 0 - 9,999,999
Totalizer display range: 0 – 99,999,999
Totalizers will roll over to zero when maximum
count is exceeded.
