6. INSTALLATION
6.1 Considerations at Installation
(1) Flush the piping assembly.
Flushing must be performed before meter installation. Install a short pipe in place of the meter at this time (see
diagram below).

(2) Arrange piping so as to
facilitate drainage.
(3) S t r a i n e r s h o u l d b e
inspected on a regular
basis.
6.3 Standard Installation, Vertical Line
(1) If the ow direction is from top to
bottom, switch the places of meter
and strainer.
(2) Installing the strainer at "A" will
make net reinstallation difficult at
cleaning; we recommend to install
the strainer at "B".

(2) Install the meter free from pipe strains.
(3) The meter must be installed on the discharge side of the pump.
(4) If the meter is to be used under tank head, give a head pressure greater than the losses with the piping
system, strainer, meter, etc.
NOTE: Pressure losses of the Smart Ultra OVAL and strainers are stated in the GENERAL SPECIFICATIONS.
(5) The meter installation is correct if the ow direction conforms to the arrow mark on the meter body.
(6) The strainer should be located upstream of, and as close to the meter as possible.
(7) Since the sensor in the Smart Ultra OVAL operates on the principle of sensing changes in magnetic ux
density, it must be isolated from the influence of any external magnetic flux. In order to minimize the
influence of external magnetic flux, select an installation location at least 5 meters away from existing
power equipment and conductors - potential sources of creating strong magnetic and electric elds, such
as motors and generators.
(8) In case electric heating is desired, consult the factory.
(9) In the heat retention work, aviod covering up the ns and heating tube with lagging material.

6.2 Standard Installation, Horizontal Line
Do not install the meter in
a position like this.
