The plug-in display unit SD 1 may be used with any KRACHT volume counter which uses a plug-in connection according to DIN 43650.
The display unit is simply inserted between the plug and the plug socket on the volume counter. The displayed value will be the actual flow rate or
the volume. The square wave signal remains available for external processing.
Volume counters already supplied can be equipped with the plug-in display unit. To achieve this the amplifier card must be removed from the plug.
