4.2 Electrical data
Power supply 15 ... 30 VDC, 200 mA
4.3 Output-signals
Analogue output Signal: 4 ... 20 mA, isolated
Scaling: 0 to max flow
Max load: 250R
Pulse output 1 pulse per consumption unit, isolated switch,
max. 30 VDC, 200 mA (pulse length: 10 ... 120
ms, depends on flow rate)
Modbus output See chapter 9.3
4.4 Accuracy
Accuracy* ±(1.5% of reading + 0.3% FS) (optional 1% of
reading)
Temperature drift: < 0.05%/K
Stated accuracy at Ambient/process temperature 23°C ± 3°C
Ambient/process humidity <90%
Process pressure at 0.6 Mpa
Repeatability ± 0.25% of reading
*Specified accuracy is valid only within the minimum and maxmim flow
rates that are indicated in section 4.5.
