Taking A Measurement; Basic Measurement With The Measure Screen - Water Analytics AquaMetrix AM-FOG Installation And Operation Manual

To calibrate the probe, press the menu icon in the top left and bring up the menu screen
(right). Select Calibrate.
Follow the instructions:
1. Immerse the probe in a bath of water up to the top of the PVC pipe. (Do NOT
immerse the head unit.) We use a 3" PVC pipe capped at the bottom, and we will
provide such a unit for sale.
2. Allow about a minute for the probe to equilibrate in water.
3. Press the Water Calibration
4. When the Alert window appears select Calibrate. This starts the one-minute
calibration.
5. The Calibration screen will return.
6. Hang the probe in the air for at least one minute to let the probe equilibrate.
7. Press the Air Calibration
8. When the Alert

9. The Calibration screen will return.
Note that the Calibration screen reports the results of the calibration: the date of both calibrations and
the slope and the intercept of the graph that converts frequency values to the calibrated range of 0 to
10,000.

6 Taking a Measurement

Basic Measurement with the Measure Screen

Once the configuration is set you are ready to take measurements. The screen
that you, as a ordinary user, will use on a daily basis is the Measure screen.
This is simply a bar screen that is color coded: Dark blue is water, light blue is
air, orange is FOG and brown is sludge. (Because sludge is not yet operational
the default range in the Configuration screen should prevent it from appearing
in measurements.)
Try holding your hand around the middle of the probe. Your hand has
approximately the same dielectric constant as FOG so the part of the probe
surrounded by your hand will turn orange. It will take a full minute to
equilibrate and settle into a light blue bar with an orange bar in the middle.
Next, try sticking the probe in water and watch the bottom part of the probe
in water turn dark blue. Notice that the percentage of air, FOG, water and
sludge appears to the right of the bar graph.
Note also that the app determines the top of the liquid level of the
interceptor. It does this by determining the lowest level of the air column. The
app uses the top of the trap to calculate composition percentages with
respect to the liquid volume. A red triangle appears more than 25% of the
volume of the interceptor is occupied by FOG (plus sludge when available).
