The MultiRanger is pre-programmed for common PMD flow calculations. If your PMD is not listed, select the appropriate Universal Flow Calculation.

Associated parameters Max Head (P603), Max Flow (P604), and Min Head (P605) may be scroll accessed. If Operation is not set for OCM (P001 = 6), this value is preset to 0. If Operation is set for OCM, it is preset to 1.

Use this parameter if the Primary Measuring Device (P600) is set to 1 (exponential). It creates an exponential curve with end points set by Max Head (P603) and Zero Head (P604) and with the curve based on the specified exponent.

If P601 = 1, the flow characteristic is a straight line

A Word on Exponents

The exponential equation is

Q= KHP601

Where:

Q = flow

K = internal constant

H = head

Parameters

Use the exponent specified by the PMD manufacturer, if available, or the sample value given below.
