Real Time (registers 17009, 17010)
This register is a floating-point representation of time, formatted as HH:MM:SS. For example, a value of
180205 represents a time of 6:02:05 PM.
Totals
The instrument provides Grand Total (17011), Daily Total (17015), Hourly Total (17019) and a Polling Total
(17023). It also provides Previous Day Total (17027), Previous Hour Total (17031), and Previous Polling
Total (17035). These totals are available in terms of configured units and base units. Refer to Base Units/
Configured Units, page C-11
, for details.
Pulse Output Pulses (register 17077)
When the pulse output is enabled (see Pulse Output Source, register 4000), this register indicates the
current number of output pulses to be sent to the output relay, based on the configured duration. In a typical
application, this register will generally indicate a small number, then quickly count down to zero. In a
situation where pulses are being cached, the pulses register will indicate a large value. When the pulse output
is disabled, a user can use this register to write a desired number of pulses to be output, for use in testing end
devices. Users can also perform this output test from the software Pulse Output configuration screen. For
details, see
Pulse Output Testing, page 68
.
Analog Output Current (register 17079)
When the analog output is enabled (see Analog Output Source, register 4005), this register indicates the
calculated output current based on the low and high values and the instantaneous flow rate. When the analog
output is disabled, a user can use this register to write a desired output current for use in testing end devices.
Users can also perform this output test from the software 4-20 mA Output configuration screen. For details,
see 4-20 mA Output Testing, page 65 .
Calculated K-Factor (register 17081)
This register represents the K-factor that was used for the most recent calculation interval. This number
is calculated based on the factor type (register 2008), the instantaneous frequency from the flow meter,
calibration frequencies (registers 2011 through 2033), and calibration factors (registers 2035 through 2057).
The unit of measurement for this register is pulses per configured factor unit. Once the K-factor is calculated
based on frequency and K-factor points, this value is multiplied by 1000 if the user chooses to read the
volume in units x 1000, and it is divided by the Standard Measurement Correction Factor (register 2059).
