Diagnostics Menu
Use the Diagnostics Menu to evaluate signal integrity, simulate operation, and review the system
files. The system log files contain time/date stamped messages including power on, power off,
programming time outs, parameter faults, incorrect password entry, and other various information
relative to system operation and programming. See below for a description of the items in this
menu that evaluate signal integrity and simulate operation.
Spd Sound Ratio , is a unitless measure between 0 and 1 that compares the Fluid Temp 1 speed
of sound to the TOF_Calc speed of sound. The closer the value is to 1, the stronger the
correlation.
Signal Quality , is a measure of the amplitude of the ultrasonic signal from 0 to 100%, that is
normalized for gain, fluid, and pipe materials. A value of 85% or higher is considered
acceptable. A value below 85% is considered unacceptable and Chapter 6 of the manual should
be referenced for steps on how to troubleshoot the application.
Sim Flow , is an input used for testing the meter to verify that the programming is correct.
Simulated Flow allows you to enter a flow rate, and in turn, the meter will update all analog
outputs. The meter will output these new values and will use them to calculate a new density for
mass flow measurement. Note: when your diagnostic work is complete, make sure to return the
value to zero to allow the electronics to use the actual transducer values.
