Design
Flow Velocity Ranges 0-0.1 m/s to 0-10 m/s (0-0.3 ft/s to 0-30 ft/s)
The range can be set locally through the DOP or remotely through the SFC.
See Table 7 for minimum and maximum ranges by diameter.
Electrical Conductivity of
Liquid
300 microsiemens/m (3 micromhos/cm) minimum.
Liquid Pressure and
Temperature Ranges for
Detector
See Table 5, Page 14.
Damping Time Constant Variable from 0.5 to 199.9 seconds.
Low Flow Cutoff Current output corresponding to 0-10% of set range (variable integer)
Dropout Pulse output corresponding to 0-10% of set range (variable integer) for 20 kHz maximum
Lightning Protection 12 kV, 1000A
Incorporated into the power source and external input and output terminals.
Power Failure EEPROM retains data record of total flow volume when pulse output is used (retention period
approximately 10 years).
Input (Transmitter) Detector flow signals plus external selections that drive a semiconductor or no-voltage open-
close contact signal for any one of the following functions:
•
External 0% lock:
Enables 0% stop of the flow indication, analog output, digital output, and
pulse output via contact input.
•
External automatic zero adjustment:
Adjusts the zero point by contact input.
•
External range changeover:
Switches dual range or forward/reverse range by contact input.
•
Built-in counter reset (optional for pulse output model):
Resets the total flow volume value of
the built-in counter by contact input.
