The source of units depends on the operation:
Flow Sampler
Based on Volume and Time
To trigger a flow sampler relay based on flow, use P111[r]=41 and set the other
parameters:
By using a mantissa (P641) and an exponent (P642), the relay contacts can be based on a
volume other than a multiple of ten.
During the periods of low flow, the sampler may be idle for lengths of time. Program P115
to a time interval in hours to drive the sampler. The sampler will operate based on the
volume of flow or the time interval, whichever comes first.
