1 PRODUCT DESCRIPTION

1.1 GENERAL PRINCIPLE

AURIGA is a single jet water meter designed in accordance with EN 14154, ISO 4064 and OIML R49
standards. It has a MID certification and complies with the standard applying to materials in contact
with water. It is a measuring device approved for invoicing that must be handled with care.
AURIGA is made of a brass body (1) containing the hydraulic part, a register (2) and a grey ring (3)
that seals the register to the body. The ring rotates freely ensuring optimal legibility of the data. The
hole (4) enables on-site sealing of the meter. The 2 arrows (5) indicate which way the water is
flowing.
