External Totalizers and Flow Samplers – MR 200

The source of units depends on the operation:

Operation

Units Source Parameter

OCM (P001=6)

P604–Maximum Flow, or P608–Flowrate Units

Pumped Volume (P001=7)

P051–Max Volume

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:

Counter Formula

1 Contact per P641 x 10P642 units

Operation

Units Source Parameter

OCM (P001=6)

P604 – Maximum Flow, or P608 – Flowrate Units

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.
