Samples - Omega FMG600 Series User Manual

Comment:
The measurement unit selected for "Flow Rate" is automatically set for all other flow-rate quantities referred
to in the Programming menu.
The measurement unit selected for "Total Volume +" is automatically set for all other flow-volume quantities
in the Programming menu.
The measurement units for the "Total Volume –" and "Total Difference" quantities can be selected as need
be, and their selection will not affect any other measured quantities to be set within the Programming menu.

User-specified units
When defining a user-specific unit, it is necessary to enter a conversion constant (a multiple of the standard
flow-rate or volume units – "l/s" or "l", then depress
define number of decimal positions, depress
Example: the desired flow rate unit is US barell per second; the conversion constant is 0.006283811; unit
name bl/s; number of decimal positions 0.000.
The same procedures apply to parameter setting with Flow rate, Total volume +, Total volume – and Total
difference.
While setting the parameters of Operational time, Per cent flow rate, Last error and Dosing, the options to
select from are only "DISPLAY" and "NO DISPLAY".

7.1.2. Samples

The number of samples N, on the basis of which the average flow rate value is determined, can be set within
the range of 1 to 255. While the measurement frequency is 6.25Hz (or 3.125, 1 or 0.5Hz), fast (step)
changes in the flow rate will be smoothened within the interval of 0.08 to 20.40s (0.16 to 40.80s, 0.5 to
127.5s or 1 to 255s). The averaging feature is useful in the cases where the flow through the meter sensor is
unstable, the fluid is turbulent or where there are air bubbles trapped in the fluid flow.
The averaging function helps suppress fast changes in the fluid flow rate. Average flow rate as measured
and displayed is the parameter used to calculate other meter outputs.
