Linearizer
The linearizer function is designed to correct for devices that will
vary in a nonlinear way as a device changes in flow/frequency. It
can take nonlinear input and change it to a more linear analog
output. (Figure 7)
Ex. A meter that has a range of 0.5-2 GPM. If at 0.5 GPM (=100HZ) it has a
K-factor of 1800, at 1.5 GPM (=200Hz) it has a K-factor of 1850, and at 2.0
GPM (=300Hz) it has a K-factor of 1900. Using a linearizer would ensure
the most accurate results over the full range of flow.
Turn On Linearizer: Press the slider to turn the linearizer On and Off. The
Slider will turn pink to indicate it is On. Press the Set button for selection
to take place.
Changing Values: To change values in the table, press on the desired data point that needs changing.
Enter in new values and press the Set button to save the changes.
Entering New Values: To enter in values to the linearizer, press the (+) button. This will bring up the
option to type in a desired frequency and corresponding K-factor. After values are entered, press Add,
this should input the values into the table. Continue to the next Row and repeat the process for each
additional value needed. There are 10 rows available, but it is not required to fill them all. When desired
amount of points are entered, press SET to save the changes.
Deleting Values: To Remove a value, press the slider next to the row that needs to be delete. The slider
will turn Pink to indicate the row is selected. When all desired rows are selected, press the (
to remove them. Press Set to save the changes.
Computer Toolkit
The EDGE toolkit was designed to
allow users to connect to a PC and have
access to scaling and monitoring of the
Sensor. This program will allow users to input
Flow Units, Time Base, Max Flow Rates, and
K-factors. It will also allow the user to view
real time flow, force analog outputs to
specific values, and set up a linearizer table.
