1.4 STANDARD FEATURES AND SPECIFICATIONS

A built-in user interface & display
A single 4 – 20 mA output for flow rate
Two programmable open collector pulse outputs. Outputs may be programmed to provide:

* an indication of flow direction

* a scaled pulse for totalizing flow

* 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 flow laboratory

against standards that are directly traceable to

government standards. A certificate of calibration

accompanies every meter.

ACCURACY

± 0.4% of reading from 3.3 to 33 ft/sec

± 0.8% of reading from 1 to 3.3 ft/sec

± 0.0075 ft/s at flows less than 1 ft/s

PROGRAMMING

Factory programmed for specific application

MEMORY

Nonvolatile memory retains all program parameters

and totalized values in the event of power loss.

DISPLAY

Alphanumeric LCD displays total flow, flow rate,

flow direction & alarm conditions

OUTPUT SIGNALS

Isolated 4 – 20 mA analog output for flow rate

Two programmable open collector pulse outputs

(configurable for frequency, pulse or directional

flow)
