Hello and welcome to Pulsar Measurement academy. My name is Shaun Minton, and in today's how-to
video, we're going to teach you how to use the Ultra 4 controller in an open channel flow
application. From the home screen first, we'll enter the password 1997 and then press enter.
Next, we'll get into the Ultra Wizard setup by hitting the left arrow key and enter.
We'll hit enter again and then go to option three flow by hitting the down arrow button
two times and then hitting enter again. To get out of the Ultra Wizard, we'll use the cancel key
and then right arrow. To get back into the quick setup menu, we'll hit enter once and then twice.
Now, it's time to set up our primary measuring device. As mentioned, we'll be setting up a
Parshall flume. That's option four, so we'll hit the down button three times and then enter. Now
it's time to set up our calculation option. For a Parshall flume, we want to use ratio metric,
so we'll hit the down arrow button one time and then enter. We can set up alarms for our
Parshall flume, but in this instance, we won't, so we'll simply hit enter. For open channel flow
applications, the best option is our dBMACH3. It's currently already highlighted. All we need to do
is hit the enter button. Now, let's set up our volumetric units. We'll set this up for US gallons
by hitting the down arrow button four times. Once we see US gallons, we simply hit the enter button.
Let's set up our time units. For this particular application, we'll use the second option per
minute. We'll hit the down arrow button one time and then enter. Time to set up the measurement
units. For this application, we'll be using the measurement unit of feet. We'll hit the down arrow
button three times and then enter. To set up the empty distance, we'll want to measure from the
bottom of the cone of the dBMACH3 to the bottom of the flume. In this case, we'll set two feet as
that parameter. We'll hit the number two and then the enter button. For minimum head, we can set the
default as zero, as we're working with a Parshall flume. We'll simply hit the enter button. Maximum
head is the maximum amount of water the flume is rated for. In this case, we'll set it at 1.5 feet
and then hit enter. It's time to set up the totalizer. In most cases, we'll want the totalizer
on. It's also the default setting, so we'll simply hit enter. The totalizer multiplier sets
the factor by which the calculated volume will be divided or multiplied before being displayed.
In this case, we'll multiply by a factor of one by hitting enter. Now it's time to set up the maximum
flow rate for the parameters that we've previously set. In this example, we'll set a maximum flow
rate of three thousand twenty-seven gallons and then hit enter. For this example, we've used a one
foot Parshall flume. Now it's time to set up the throat width of the Parshall flume. In this case,
it's one foot or twelve inches. We'll hit the down arrow button twelve inches and then hit enter.
It's time to set up the auxiliary line or what the display will show the end-user. In this case, we
want it to show totalizer. We'll hit the up arrow once and actually choose the fourteenth option and
then hit enter. One of the great features of the Ultra 4 controller is the ability to record data.
We'll go to the data log option and hit enter. From there, we'll go to data log set up and hit
enter again. We'll select data log. We'll hit the down arrow button, enter again, and then
choose our log value. Now let's set up our logging interval. We'll do this by hitting cancel twice.
We'll go down to log settings and hit enter again. From here, it's simply a matter of setting up your
log interval. In this case, we have it set up for five minutes. If that time is good, we simply hit
enter again. We're now in the sample interval, where we set up our time for five minutes. If this
meets your requirement, simply hit enter. If you need to change the interval, put in your interval
and hit enter. And now it's time to get out of the data log option and back to the home screen.
We simply do this by hitting cancel several times. Now that we've canceled out into run mode,
we simply hit enter. And that takes us back to the home screen. Thanks for watching today's video
