Sets the site ID (maximum of 8 digits). The site ID is on all data printouts. Use this
feature when multiple sites are monitored with a single flow meter or if data readings
from multiple flow meters are collected.
Note: A text site ID can be set with InSight data management software and an
RS232 connection.

Sets the direction of velocity. Options: UPSTREAM (NORMAL), DOWNSTREAM or
ALWAYS POSITIVE
Sets the measurement units for velocity. Options: ft/s, m/s
Sets the velocity cutoff. Use when the site has low velocities and frequent low
particulate concentrations that prevent velocity measurements.
Example 1: Velocity cutoff = 0.20 ft/s, Velocity default = 0 ft/s
If the velocity is less than 0.20 ft/s, the meter saves a value of 0 ft/s until the velocity
increases to more than 0.20 ft/s.
Example 2: Velocity cutoff = 0.20 ft/s, Velocity default = 0.20 ft/s
If the velocity is less than 0.20 ft/s, the meter saves a value of 0.20 ft/s until the velocity
increases to more than 0.20 ft/s.
Sets the velocity value that is used when velocity cannot be measured.
