Reading and data
16.1
Reading
flowIQ® 3100 can be read in three different ways:
•
Visual reading of the legal display
•
Receiving the Wireless M-bus signal, which is emitted at intervals of 16 or 96 seconds, depending on the
meter configuration, alternatively receiving the wired M-Bus datagram
•
Reading via the optical eye, e.g. by means of Kamstrup
A/S’
wireless optical reading head, or optical reading
head with USB connector.
16.2
Volume measurement
The meter calculates water flow currently according to a fixed measuring cycle.
When the meter is in normal mode a measurement is carried out every four seconds, and after a total of 32
seconds the meter reading is updated in the display.
Every 24 hours the meter reading is saved in the daily register. The register includes data for the latest 460 days.
The daily register can be read via the optical eye.
The Wireless M-Bus signal is normally configured to include current meter reading.
The Wired M-Bus signal always includes current meter reading.
16.3
Data function: Target volume
flowIQ® 3100 saves the meter reading on the first day of the month in the target volume register. Data is stored
in the monthly register. The register includes data for the latest 36 months.
The Wireless M-Bus signal includes target volume of last month if selected during customer specific
configuration. The target volume of last month can be selected combined with a number of combinations of
*water and ambient temperature (see paragraph
Optional register in data logger
).
Reading the target volume is used by waterworks for invoicing and final settlement with the consumer.
The complete register of target volumes for the latest 36 months and/or 10 years can be read by means of the
optical eye.
*
Measuring the water temperature is only valid for meter sizes 1.6, 2.5 and 4.0 m
