Typical Marking
Marking can vary according different market or
metrological specifications.
AMR fitting
The dial of the 620 meter is equipped as standard
with a pointer able to activate the HRI sensor.
The HRI reproduces the mechanical register index
exactly, by detecting the direction of rotation of
the pointer. It provides a reliable pulse- and data
interface for remote and mobile readout. The
HRI can be fitted in the field on already installed
Sentinel water meters or ordered factory fitted to
the meter.
For more information refer to the leaflets
LS 8100 and LS 3300
The HRI is available as three versions:
1. HRI Pulse Unit (A-version)
The litre pointer activates the HRI allowing a basic
resolution of one litre per pulse. The output pulse
value can be factory set using the divisor D (e.g. D
= 100 means 1 pulse per 100 litres).
The possible pulse output D values are:
1 / 10 / 100 / 1000 / 2.5 / 25 / 250
2. HRI Data Unit (B-version)
The HRI Data Unit is a data interface which supplies
the meter reading as well as the serial or customer
number. This version additionally provides a pulse
output as described above.
The HRI Data Unit can be connected to a M-Bus
network for remote read or a MiniPad for mobile
inductive read (MiniBus), both in accordance with
the IEC 870 protocol.
3. Sensus((S))cout-S Radio Unit
Integrated Sensus((S))cout radio with the usage
of long term proven and reliable HRI sensing
technology. Radio read is made via the handheld
Psion WA pro and Dokom mobile (WinCE) software
Installation and Maintenance Instructions
For complete installation instructions, please refer to MD1001INT manual.
The 620 meter must be installed in a low point of the pipeline, with the arrow
cast on the body showing direction of the water flow. Before fitting the water
meter, all pipework must be flushed out to remove all impurities.
An upstream stop valve is recommended to allow installation and removal of
the water meter.
During tightening, the meter must be maintained in position with a standard
tool using the flat on the meter body.
When turning on the water supply, the upstream valve must be opened
slowly so that the water fills the meter as smoothly as possible.
No special maintenance is required.
