7. Warranty and Service
7.1 Warranty
ALIA responsible for 18 monthes guarantee period of all products since ex-factory date(except man-made
sabotage),If there occurs quality problems with our products during this period,user only need to assume
the one-way freight.(Note:Please inform our ALIA representative before product sent back.)
7.2 Service
For operational issues we recommend contacting your Alia rep by phone, fax or email. These issues can
usually be resolved this way. Installation assistance for our customers is available at standard Alia service
rates.
7.3 Software Upgrade Service
We provide free-of-charge software upgrade services. Please contact the factory for more information
regarding availability of revisions or updates.
7.4 Product identification
Each AUF610 Series flow meter has a unique product identification or ESN# written in the software and
can only be accessed by the manufacturer. In the case of an equipment failure, this number, located on
menu window number M61, MUST be provided when contacting the manufacturer.

Glossary of Terms
Calibration –
Calibration refers to the process of determining the relation between the output of a
measuring instrument and the value of its input quantity a measurement standard. In non-specialized
use, calibration is often regarded as including the process of adjusting the output or indication on a
measurement instrument to agree with value of the applied standard,
Measurement Uncertainty –
Measurement uncertainty is the statistical calculation of the total error
exhibited by a measuring instrument as a result of a series of measurements taken and compared to a
known standard. The result of a physical measurement comprises two parts: an estimate of the true
value of the measurand and the uncertainty of this estimate.
Laminar Flow
- Laminar flow, sometimes known as streamline flow, is when a fluid flows in parallel
layers, with no disruption between the layers. In fluid dynamics, laminar flow is a flow regime
characterized by high momentum diffusion, low momentum convection, pressure and velocity
independent from time. It is the opposite of turbulent flow and is generally characterized by a Reynolds
number less than 3000.
Random Error –
(also known as Precision Error) The random error is the component of a measurement
uncertainty analysis that characterizes the inherent error of the instrument based its fundamental
measurement technology and the stability of the inherent parts.
Reynolds Number –
The Reynolds Number is a dimensionless number in fluid mechanics that
characterizes the ratio of inertial or driving forces to the restrictive or viscous force within a process..
It is used with other dimensionless numbers, to provide a criterion for determining the hydraulic flow
profile and predict flow geometry within a pipe.
Systematic Error –
(also known as Bias error) The systematic error is the component of a measurement
uncertainty analysis that characterizes the error of the instrument caused by environmental, installation or
human factors. This can often be minimized with careful installation and maintenance.
