Performance

Refer to the following tables.
Diameters 2.5 mm to 15 mm (0.1 in. to 0.6 in.):
Accuracy at Vs ≥40%
Vs (m/s)
1.0 ≤ Vs ≤ 10 ±0.5% of indicated value
0.1 ≤ Vs ≤ 1.0 ±(0.1/Vs + 0.4%) of indicated
value
Diameters 25 mm to 600 mm (1 in. to 23.6 in.):
Accuracy at Vs ≥20%
Vs (m/s)
1.0 ≤ Vs ≤ 10 ±0.5% of indicated value
0.1 ≤ Vs ≤ 1.0 ±(0.1/Vs + 0.4%) of indicated
value
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.
300 microsiemens/m (3 micromhos/cm) minimum.
See Table 5, Page 14.
Variable from 0.5 to 199.9 seconds.
Current output corresponding to 0-10% of set range (variable integer)
Pulse output corresponding to 0-10% of set range (variable integer) for 20 kHz maximum
12 kV, 1000A
Incorporated into the power source and external input and output terminals.
EEPROM retains data record of total flow volume when pulse output is used (retention period
approximately 10 years).
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.
