7.5 THE SITE SETUP DATA MENU
This menu provides data pertaining to transducer characteristics and operation. Some menu items
are for technical support interpretation only.
Reynolds # 318017
Siemens 2 Channel [1] Channel 1
Current Reynolds number
Liquid Data
Reynolds # 1020 corrects the current flow rate in accordance with this Reynolds number. This num-
ber is determined from pipe ID, current flow rate and liquid kinematic viscosity.
LIQUID DATA MENU ITEMS
fx (drive) Current Transmit drive code selected during Initial Makeup. The drive code con-
trols the sonic transmit signal.
N (burst length) Transmit burst duration selected during Initial Makeup. To change N count
press <Right Arrow>. At equal sign enter numeric value (1 to 9 only).
Ltn (in/mm) Spacing distance between the transducers. It will be in inches or millimeters,
depending on default units.
Vfmax The flow velocity (in selected units) corresponding to one whole cycle offset
between upstream and downstream receive signals.
Vs max m/s Maximum correctly calibrated Vs for current transducer spacing.
Vs min m/s Minimum correctly calibrated Vs for current transducer spacing.
Empty % Value of Empty Alarm Setting. The meter will declare an empty status if signal
strength drops below this value.
Samples/Cycle Digital sampling rate.
Max Damping Maximum signal damping. Use to average digital data when an unstable condi-
tion occurs.
Min Damping Minimal signal damping. Use to average digital data when an unstable condition
occurs.
HF Flow registration correction parameter.
