16.4
Data function: Target date
The date in the month for which the meter reading is sent via the radio signal.
16.5
Data function: Reverse Volume
Module 46/66:
Reverse flow is counted and logged in a separate internal register in the meter and can only be read on a monthly
basis. If a meter has been incorrectly installed (with reverse flow direction) for a longer period, the reverse volume
could be read in the monthly logger. This log is, similar to the legal log, an absolute log
–
which means that the total
reverse consumption are shown in the latest monthly log at the end of the month. So even if the fault is corrected,
the total reverse consumption cannot be seen until the end of the month.
The register can only be read via the optical eye with LogView.
Other modules:
If reverse volume is selected in the R-package the actual REVERSE volume is sent via the radio signal immediately.
The total reverse volume is measured and recorded whether the info code is being activated or not. It should be
emphasized that the register for backwards volume is NOT covered by the type approval, and therefore not
approved for billing purposes.
The legal volume register, V1, and thus the meter reading is not affected by the reverse flow.
16.6
Data function: Date/time stamp
When selected date and time is sent with volume data.
16.7
Data function: Battery capacity
Remaining battery capacity according to the selected radio package.
16.8
Data function: Radio disabled
‘Radio disabled’ can be selected from software version T1 and onwards. When radio disabled is selected the radio
will not be activated in normal operation. The only way of enabling the radio is by means of DataTool.
16.9
Data function: Maximum flow and minimum flow
flowIQ® 3100 registers maximum and minimum flow on a daily as well as monthly and yearly basis. (Depending on
which module selected)
Maximum and minimum flow are calculated as the largest and the smallest value, respectively, of a number of
current flow measurements. The average period used for all calculations can be selected in the interval 1...120
minutes in leaps of one minute. The choice must be made when submitting the order.
If no choice is made, the average period will by default be 2 minutes.
Wireless M-
Bus signal may contain ’maximum flow’ for latest day or month, if this is chosen by the customer
-
specific configuration. Values of maximum and minimum flow are saved in both daily and monthly and yearly
registers. Daily registers of the latest 460 days, monthly registers of the latest 36 months and registers of the latest
10 years are always readable via the optical eye.
The development of maximum flow can indicate an error in the water installation. If e.g. max flow falls over a longer
period, this can be a sign of a blocking in the installation or a leakage in the supply pipe before the meter. Maximum
flow rate can also be used for an assessment of whether or not the correct size meter has been installed.
Logging the minimum flow is a valuable information when tracing excessive consumption from temporary leaks.
