Download Sigma 950 - Hach Flow

Option
Description
LEVEL UNITS
Sets the measurement units for level.
PRIMARY DEVICE
Selects the primary device.
PROGRAM LOCK
Enables or disables the program lock. The program lock prevents unauthorized use of
the keyboard and access via RS232 or modem. The program lock password is
9500 and cannot be changed.
SAMPLER PACING Enables or disables sampling. Sets the sample interval. Options: 100 gallons (gal),
liters (ltr), cubic meters (m3), acre-feet (af) or cubic feet (cf)
SITE ID
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.
TOTAL FLOW
UNITS
Sets the measurement units for total flow. Options: gallons (gal), liters (ltr), cubic
meters (m3), acre-feet (af) or cubic feet (cf)
VELOCITY
DIRECTION
Sets the direction of velocity. Options: UPSTREAM (NORMAL), DOWNSTREAM or
ALWAYS POSITIVE
VELOCITY UNITS
Sets the measurement units for velocity. Options: ft/s, m/s
VELOCITY
CUTOFF
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.
VELOCITY
DEFAULT
Sets the velocity value that is used when velocity cannot be measured.
