1.3.5.7 The Mass Flow Option
Use this option to calculate mass flow from a static fluid density. Complete the following steps to enter the static
density of the fluid:
1. From the ADVAN menu, scroll to MASS and press [Enter] .
2. Scroll to Yes to activate Mass from Static or on No to disable this option.
a. If you select Yes , enter the Fluid Density (0.062 to 624.220 lb/ft
3
or 0.001 to 9.9675g/cc).
b. For either option, press [Enter]
.
After responding to the above prompt, the meter returns to the ADVAN window.
1.3.5.8 The Code Length Option
Use this option to select the size of the transducer transmission signal. This option is helpful when measuring flow in
small pipes. You can choose from the following selections:
• AUTO - The meter will automatically determine the code length (short or long) which is based on pipe size and
transducer type.
• SHORT - is just few pulses with no code pattern built in
.
In some cases, the diameter of the pipe is so small that
it does not give each transducer the necessary time to send a series of signals before receiving a series of
signals.
SHORT
is also a good selection for pipes made of materials such as PTFE

which tend to blur the signal
pattern.
• LONG - is a series of approximately a dozen pulses that have a distinctive binary pattern, easily recognizable
during auto correlation.
Complete the following steps to select the code length:
1. From the ADVAN option menu, scroll to CODEL and press [Enter] .
2. Scroll to the desired Xmit Code Length and press [Enter] . AUTO is the default.
After responding to the above prompt, the meter returns to the ADVAN window. Press [Escape] three times to return
to the Channel PROGRAM , or four times to return to the Keypad Program.
