temperature. Press Enter. The following will appear. You will have to press the right arrow key several times to see all of the options displayed in the following menu:
FLOW RATE UNITS OF MEASURE
• GPS • • GPM • • GPH • • MGD • • CFS • • CFM • • CF-
Pressing the right arrow key several times will move other units onto the display.:
FLOW RATE UNITS OF MEASURE
• •CFH • • CFD • • LPS • • M3S • • M3M • • M3H • • M3D • • AFD •
NOT MEASURED will also appear if you keep moving with the right arrow key. This step establishes the units of measure the flow meter will use in all subsequent displays and calculations.
GPS = gallons per second; GPM = gallons per minute; GPH = gallons per hour; MGD = millions of gallons per day; CFS = cubic feet per second; CFM = cubic feet per minute; CFH = cubic feet per hour; CFD = cubic feet per day; LPS = liters per second; M3S
=cubic meters per second; M3M = cubic meters per minute; M3H
=cubic meters per hour; M3D = cubic meters per day; AFD =
TOTALIZED VOLUME UNITS
• GAL • • MGAL • • CF • • L • • M3 • • AF •
This step determines the units value the flow meter will use to record the totalized flow volume that passes by. GAL = gallons; MGAL = millions of gallons; CF = cubic feet; L = liters; M3 = cubic meters; AF =
For the next several substeps you must have the appropriate sensor attached to the flow meter's Parameter Port or Rain Gauge Port (for the Rain Gauge or YSI 600 Sonde) to take advantage of the capabilities. You can only have D.O./temper- ature, pH/temperature or temperature alone on a given flow meter, unless you use the YSI 600 Sonde. The YSI 600 Sonde pro- vides multiple outputs simultaneously. You can use the Rain Gauge with the YSI 600 sonde if you use a
Note
The pH or D. O. probes do not attach directly to the flow meter, as their output signals are very low. You must also have the appropriate amplifier box connected between the probes and the flow meter.
Remember that programming for one type of sensor will prevent the display of any references to the other in later program steps. All sensors but the rain gauge are mounted fully submerged in the flow stream. The pH and D.O. probes must be kept con- stantly wet or they can be damaged.
