BB100 Operation
To operate, the meter requires between 11 and 28 VDC @ 300 mA. The meter can be
powered either by the vehicle’s battery or the supplied AC/DC power supply.
When the power is attached, the meter will:
•
Test the 8-segment displays, then the LEDs.
•
Display the serial number (ex. 1234).
•
Display the code version (ex. COdE 1.1).
•
Display the calibration date (ex. CAL 12.25.1998).
•
Display the analog output range (ex. A 0.0 – 5.0 ).
•
Display the volume flowrate range or total volume range corresponding to the analog
output range (ex. 0 – 150). The units will be shown on the LEDs.
•
During this process, the analog output will be held at 1.000V and then 4.000V. This can
be used to check your data acquisition system hook-up to the BB100.
(To jump past the above steps, press either the SEL or CLR key).
The meter will then show the operating mode and the flowrate or total flow. The modes are
indicated by the 3 LEDs. The available modes are:
1.
“Liters per Minute” if the “LPM” LED is on.
2.
“Cubic Feet per Minute” if the “CFM” LED is on.
3.
“Total Flow in Liters” if the “LPM” and “TOTAL” LEDs are on. Press “CLR” to clear
the total flow to zero.
4.
“Total Flow in Cubic Feet” if the CFM” and “TOTAL” LEDs are on. Press “CLR” to
clear the total flow to zero.
To change the operating mode, press the SEL key.
To zero the total flow, press the CLR key. The modes of the meter can be changed and the
meter will still continue adding to the total flow. CLR has no effect on flowrate readings.
The BB100 has integral damping tanks and oil and water separators on both the inlet (upper)
and outlet (lower) sides of the meter. Blow-by can condense in the meter leaving liquid in
the tanks. The amount of liquid collected in the damping tanks over a period in time depends
on the engine and the plumbing from the engine to the meter. The damping tank has a
transparent sight glass (made of plastic). When liquid begins to fill the sight glass, it is time
