OCM PARAMETERS (P600 - P607, P610, P611, P620, P621)
If The HYDRO+ is used to monitor open channel flow, alter the following parameters
as required.
The HYDRO+ calculates "head" as referenced to Empty (P006) or OCM Zero Offset
(P605), when Operation is set for "OCM" (P001 = 6). Flowrate, based on head
(at the "point of measure" specified by the PMD fabricator) is also calculated.
P600 (G) PRIMARY MEASURING DEVICE
Enter the type of primary measuring device (PMD) used.
If Operation is not set for "OCM" (P001 = 6), this value is preset to "0". If
Operation is set for "OCM", this value is preset to "1".
The HYDRO+ is preprogrammed with the flow constant for common PMD
flow calculations. If the PMD used is not specifically identified, select the
appropriate Universal Flow Calculation.
Associated parameters (as indicated below), Max Head (P603), Max Flow
(P604), and Min Head (P605) may be scroll accessed.
values: 0 = off (no calculation)
1 = exponential (see P601)
2 = Palmer-Bowlus Flume (see P602)
3 = H-Flume (see P602)
4 = Universal Linear Flow Calculation (see P610, P611)
5 = Universal Curved Flow Calculation (see P610, P611)
6 = BS - 3680 / ISO 4359 Rectangular Flume
7 = BS - 3680 / ISO 1438/1 Thin Plate V-notch Weir
