ENERAL PRINCIPLE
AQUILA is a precision measuring instrument. It has been designed and manufactured with
great care. It was developed to fulfil the European Directive EN 14154 (MID approval), the OIML
R49 and ISO 4064 standards, as well as the food grade requirements (ACS). It is a measuring
device approved for invoicing. It must be handled with care.
AQUILA is a single-jet meter. It is made up of a cylindrical body with two nozzles. These nozzles
have thread ends. While unpacking the meter, check the indications on the register to make sure
it is the required product.

EASURING PRINCIPLE
The stream of water and the rotation of the turbine produce the following disturbances that
are dependent on flow velocity and blade position.
A centrifuge effect (4) is caused by ejection of water by the blades towards the periphery of the
chamber.

technology. Water enters through the
inlet nozzle, drives the turbine at a
speed proportional to flowrate and exits
through the outlet nozzle.
Water enters the measurement chamber
at a tangent through a converging port
(1). The port increases the kinetic energy
of the stream (2) while significantly
limiting head losses. Water enters the
chamber as a converging stream.
