Versions
B - version without display / control unit (basic version)
D - version with display / control unit
Add-on equipment (option) - CONFIG software and RS 232 adapter for control via
MS-DOS-PC, connection to IMoCom interface

- Other bus and computer interfaces on request
Current output
Function - all operating data settable, galvanically isolated
Current 0 - 20 mA and 4 - 20 mA
Active output load max. 500 ohms
Passive output external voltage: 15 ... 20 V DC 20 ... 32 V DC
load: min. ... max. 0 ... 500 Ω 250 ... 750 Ω
Error identification 0 / 3.6 / 22 mA
Forward/reverse measurement direction identified via status output
Pulse output
Function - all operating data settable
- galvanically isolated
- digital pulse division, interpulse period non-uniform,
therefore if frequency meters connected allow for minimum
counting interval:
gate time, totalizer ≥
Pulse rate for Q = 100 % 10, 100 or 1000 pulses per second (= Hz), fixed or optionally
adjustable in pulses per liter, m
