3. OPERATING PRINCIPLE
The operating principle is based on the fluid passing through the instrument and its display through a transparent
porthole (e.g. made from glass), or is made with the returned indicator.
This passage can be further displayed with paddles (fixed or moving)), chain and drips.
In model SPO, the paddle indicates the flow rate on a graduated scale that is silk-screen printed on the porthole.
4. INSTALLATION
4.1 INSTALLING THE INSTRUMENT
Before installation, check the line connections and the instrument connections for compatibility.
As regards the SPO model, the unit shall be installed in a perfectly horizontal position and the piping shall be rectilinear for at
least 5D (D= inner diameter of the piping) upstream and 3D downstream. Remove the piece of cardboard (if any) that blocks
the paddle.
In cases when the instrument shows an arrow that indicates the direction of the flow, please comply with that indication at the
assembling stage. Moreover, if the passage fluid is at high temperature or very cold, the user shall adopt insulation/protections
that are able to minimize all differences in temperature from room temperature.
Burdening the unit with external loads is strictly prohibited and it is the user’s duty to protect it from whatever stress; all uses
as a point of support is not allowed.
To avoid all effects of galvanic corrosion, never use materials featuring a different electrochemical potential, the user shall take
all actions that are aimed at preventing such condition for the unit.
The system shall be equipped with the prescribed safety valve, to remedy over pressure values that exceed the maximum value.
For installation on piping exposed to strong vibration, please contact the customer service department.
4.2 INSTALLATION IN AREAS OF SPECIAL CONCERN
In cases when the units are installed in Areas that feature the presence of potentially explosive atmospheres, the user shall
stick to the
additional safety instructions
attached to the standard instructions.
