AMR System description:
1) Up transfer:
From concentrator to AMR control center.
(a) GPRS Communication Mode
(b)Telephone Line Communication Mode
(c) RS232 Communication Mode
(d) Ethernet Communication Mode
2) Down transfer
From the collector and water meter.
Wireless network signal has the positive of wide signal
propagation, wide coverage area ability, fast construction. One
piece of collector can connect with 128 pieces of meter maximally.
The Woltman Helix bulk water meters available in sizes: DN 50 / 2"
- DN500 / 20" with various pulse output options. Suitable for water
distribution and industrial applications. A removable Mechanical
counter assembly ensures fast and easy servicing.
The woltmann turbine meters are less accurate than positive
displacement and jet type meters at lower flow rates, however the
flow path is straight through the meter, allowing for higher flow
rates and less pressure loss than displacement style meters. The
measuring assembly does not occupy or severely restrict the flow
path resulting in a low pressure drop acrosss the meter. They are
the meter of choice along with mag meters for larger commercial
users and as master meters for water distribution system. Filters
or strainers are generally required to be installed up-stream of
the meter to protect the measuring element from sand, ice crystal
or other debris that could enter the water distribution system.
Its turbine water meters are generally available for 1 ½" to 20" or
higher pipe sizes. Woltman Helix Turbine meter bodies are commonly
made of Cast Iron or ductile iron. Internal turbine elements can be
plastic or non-corrosive metal alloys. They are accurate in normal
working conditions but are greatly affected by the flow profile and
fluid conditions, which should be given careful consideration
before installation. Consult us for suitability or alternatives
