                                              USF and USC
We have the experience of nearly fifty years in the manufacture of water meters
for use within the domestic and commercial applications. Our range of meters
now extends to include a size range from 1/2” BSP to DN 500 flanged meters.
Altecnic, along with Europe’s leading manufacturers of water meters, have
assembled one of the most comprehensive product portfolio available today.
We have meters covering a range of classes - A,B,C and D applications.


USF and USC Range
The USF and USC range of 1/2” and 3/4” meters is a compact and economic range of water
meters, which benefit from the following features
     • Single Jet Water
     • USF models suitable for use with cold water up to 30°C
     • USC models suitable for use with hot water up to 90°C
     • Direct dry dial roller indicator
     • Tamper proof cover                                                                Dimensions
     • Movable dial to enable reading to be taken
     • Operational position CLASS B when horizontal
     • Operational position CLASS A when vertical
     • Hydraulic performance in accordance with EEC 75/33

Remote reading (in combination with a remote display or a computerised reading system, it is
possible to collect and process water consumption data in multi apartment buildings, where the
access to water meter is often difficult, or wherever central reading of several meters is required.




Rate of flow control: by a suitable electrical output and with addition of electronic instrumentation,
several operations are possible, such as valve and pump control, warning systems, etc.,
according to different pre-selected rate of flow valves.
