External Totalizers and
Flow Samplers – MR 200
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.
Operation Units Source Parameter
OCM (P001=6) P604–Maximum Flow, or P608–Flowrate Units
Pumped Volume (P001=7) P051–Max Volume
