SECTION VI
AUXILIARY OPERATIONS
F1 EMULATION MODE
The flow calculation parameters can be checked for accuracy by using the emulation function, F1. A
liquid head is entered via the keypad and the OCM II will respond by displaying the flow associated with
that head. During emulation mode, all totalizing stops. This feature may be used to find a head that is
equal to a flowrate that will suit the chart recorder better.
e.g. If the maximum flowrate of a system is 721.6 litres / second, however the desired maximum
flowrate is 700 litres / second the operator may key in head values to find the head value
required to produce the desired flowrate.
