Daniels - Honeywell Enraf Operation Manual

Electrical Schematics & Drawings
When either optical switch is triggered on the downstream pass, the SVP
controller will drop White to 0VDC for 25mS and the CIU will instruct the
proving program to start or stop recording meter pulses. After the run is
complete the CIU will return to idle conditions until the next run command
is sent.

6.2.3 Daniels

Actual terminal locations for the Daniel flow computer is dependent upon
the application software being used in the Daniel flow computer. See the
appropriate Daniel manual and software information for more information.
Warning
Due to scan speed, the 2500 has limitations in flow rate when used
with small volume flow provers due to short time period between
volume detectors.
