2.4.7 Step 7 - Alarm Dialout
Mode
ALARM DIALOUT MODE allows you to program a 4210 Flow
Meter to signal a remote location through a telephone line. This
feature is useful for transmitting alarm conditions or other
essential information to a remote location.
Note
You must have the optional modem installed to make use of
this program step. The menus will not even appear unless the
flow meter has a modem installed.
The Alarm Dialout feature is useful if you need to signal a
remote location when there is a change of condition in the flow
stream that could constitute an alarm. You can program as many
as five different eighteen-digit telephone numbers into the flow
meter in decreasing order of importance. The modem is capable
of speech.
DISABLE inhibits this function altogether. CONDITIONAL lets
you program the flow meter to signal these alarms for a variety
of reasons. You can use rainfall, time, level, flow rate, dissolved
oxygen, pH, rate-of-change, a combination of conditions, or define
the operation through FLOWLINK software from another com-
puter. STORM lets you set the alarm through a combination of
rainfall and time. You can also program the interval between
calls and set up the system to reset the alarm condition by
dialing back from the remote telephone.
2.4.8 Step 8 - Printer The 4210 Flow Meter has a built-in printer. The printer is
capable of plotting linear data along with printing alphanumeric
(letters and numbers) messages. In this step you set the speed for
the chart to advance, from
1
⁄ 2" to 4" per hour.
Chart speed is set according to the amount of resolution you
want to see on the chart. If there is a great deal of activity on the
chart, you would generally choose a faster speed so the marks are
more “spread out” and are easier to interpret. If there is little
activity on the chart and you want the flow meter to run for long
periods without having to change the roll, you would pick a
slower speed.
The flow meter is capable of plotting three separate data lines on
the chart in addition to the alphanumeric messages. These lines
may indicate such things as level, flow rate, pH, dissolved
oxygen, or temperature. Note that you must have the appro-
priate sensors for pH, DO, and temperature to take advantage of
the availability of these plots.
The printer is capable of plotting over-ranges for the data lines it
plots. You can tell when the printer is in over-range if a data line
goes off the chart on the right side and then immediately starts
over again plotting on the left side.
