F-3200 Flow Meter Manual 05/14 - 0671-12 / 18325 Page 8

1.4 STANDARD FEATURES AND SPECIFICATIONS

• A built-in user interface & graphic display

• A single 4 – 20mA output for ow rate

• Two programmable open collector pulse outputs. Outputs may be programmed to provide:

* an indication of ow direction

* a scaled pulse for totalizing ow

* a high resolution frequency output to drive peripheral devices

* an indication of an alarm condition

• Empty pipe detector

• Internal self-diagnostic functions & fault alarms

CALIBRATION

Flow meters are wet calibrated in a ow laboratory

against standards that are directly traceable to

government standards. A certicate of calibration

accompanies every meter.

ACCURACY

Accurate to within:

± 0.2% of reading from 1.6 to 33 ft/s

± 0.0033 ft/s at ows less than 1.6 ft/s

PROGRAMMING

Factory programmed for specic application

MEMORY

Nonvolatile memory retains all program parameters

and totalized values in the event of power loss.

DISPLAY

Alphanumeric LCD displays total ow, ow rate,

ow direction & alarm conditions

OUTPUT SIGNALS

Isolated 4 – 20mA analog output for ow rate

2 isolated programmable opto-coupled open

collector digital/pulse outputs

(Congurable for frequency, pulse, alarm or

directional ow)

40VDC, 100mA and 1250Hz maximum

(Optional) Redundant output option with second

isolated analog output for ow rate and 2 additional

isolated programmable opto-coupled open collector

digital/pulse outputs

(Pulse outputs congurable for frequency, pulse,

alarm or directional ow)

40VDC, 100mA and 1250Hz maximum

TEMPERATURE RANGE

Liquid temperature range:

Polypropylene liner: 32° to 140°F

Ebonite liner: 23° to 175°F

PTFE liner: -4° to 212° F (266° F with remote

electronics without pre-amplier option)

Ambient temperature range: -4° to 140°F

FLUID CONDUCTIVITY

5 µS/cm minimum

MAINTENANCE

Periodically inspect the power supply cables,

cable glands and the enclosure for signs of

damage. Inspect installation and mounting hardware

for loose connections.

applications.

Input Power - Factory Selectable:

Standard - 100 - 240 VAC, 45 - 66 Hz, 12 VA typical

Optional - 18 - 45 VDC, 10 W typical

OR 18 - 45 VAC, 45 - 66 Hz, 12 VA typical

Overcurrent Protective Device Ratings:

Supply mains overcurrent protective devices with

the following ratings:

• 120VAC 50/60 Hz – 15 A

• 230VAC 50 Hz – 6 A

Wiring:

Flow signals - Use 18-22 AWG shielded cable

Standard input power - Use a three wire service

with one wire a protective earth ground. The

installation must comply with all local, state and

federal building codes.

Optional input power - Use PVC jacketed copper

cable with a wire gauge suitable for the length of

run and required maximum current carrying

capacity. The installation must comply with all

local, state and federal building codes.

Note: Specications are subject to change without notice.
