P-5 enter “1”, near blanking distance, minimum allowable
P-39 enter option “4”, display flowrate in units per day
P-40 enter option “1”, primary measuring device - exponential
P-41 enter option “4”, flowrate time units - per day
P-42 enter “1.53”, exponent from manufacturer’s specs. for 9" Parshall Flume
P-46 enter “4112”, max. flow in thousand gal./day
P-49 enter option “3”, flowrate decimal point display max. 3 digits after decimal
P-52 enter option “0”, totalizer convert display total is divided by 1 before being
displayed or 1 count per thousand gallons
P-53 enter option “2”, totalizer decimal point display 2 digits after decimal or
resolution equals 1/100th of a count
P-68 enter “32.81”, fill damping 32.81 ft/min As the head would fluctuate over a
period of hours, damping requirements would be fairly low.
Typically, the factory set damping of 32.81 can be used.
P-69 enter “32.81”, empty damping - same as fill damping
Example 6a
(Auto Zero)
Further to Example 6, the following is required:
•
alarms at 10% overflow (approx. = 1.8 ft) and 0 head
•
in the event of loss of echo, the HydroRanger I is to go into low alarm after
45 sec.
•
head to read to 1 decimal place
•
sampler contact every hour
•
head under 1" (40 thousand gal./day) not be totalized
•
4-20 mA output to respond to flow
