ROTARY COUNTER WITH OUTPUT

BADGER METER CMR - HARBERT ENGINEERING CMRE

General Description

The CMRE Model 535 Rotary Counter is an electronic replacement for the Badger Meter Model CMR mechanical rotary counter.  The mounting dimensions and shaft position are the same.  The CMRE is intended as a direct replacement for the CMR.  Both the Count (preset) value and the Delay (dwell) value are settable.  The Delay or dwell value is the number of revolutions the output relay remains energized after the Count or preset revolution value is reached; that is, the output relay is energized for the Delay number of revolutions.  A running total of the number of output cycles is maintained.  Entering the COUNT and DELAY values is a simple intuitive operation.

Differences between the CMR and CMRE are:

1)      The CMRE requires 115 volts AC at 1 amp for power,

2)      The CMRE continues to count down no matter the shaft direction, where the CMR will change count direction as the shaft direction changes.  The CMR counts down until the shaft direction reverses, and then, the CMR counts back up until the shaft reverses again.

3)      The CMRE output relay energizes when the COUNT value is reached and the relay stays energized for the DELAY number of turns, where the CMR output switch closes before the stop is reach and remains closed after the stop is pass for one turn or more.
