Flowmeter
Type P
Coil/sine wave (minimum 20mVpp or 80mVpp - sensitivity selectable), NPN/PNP, open
collector, reed-switch, Namur, active pulse signals 8 - 12 and 24V.
Frequency Minimum 0 Hz - maximum 7 kHz for total and flowrate.
Maximum frequency depends on signal type and internal low-pass filter.
E.g. Reed switch with low-pass filter: max. frequency 120 Hz.
K-Factor 0.000010 - 9,999,999 with variable decimal position.
Low-pass filter Available for all pulse signals.
Type A
(0)4-20mA - with signal calibration feature. Resolution: 14 bit.
Type U
0-10 V, 0-5 V, 1-5 V - with signal calibration feature. Resolution: 14 bit.
Accuracy 0.05%. Low level cut-off programmable.
Span 0.000010 - 9,999,999 with variable decimal position.
Update time Four times a second.
Voltage drop 2.5 Volt.
Load impedance 3kOhm
Relationship Linear and square root calculation.
Note For signal type A and U: external power to sensor is required; e.g. option PD.
