2-6 Installation
To provide for optimum system performances the following guidelines
should be observed:
1. Before use, confirm the fluid to be used is compatible with the meter.
2. The flowmeter must be installed so the shafts of the rotors are
horizontal, never vertical or “on end”. Severe damage to components
may be the result, (See Figure 2-1).
3. A mesh strainer should be installed upstream and adjacent to the
flowmeter to protect it from foreign matter such as dirt, pipe scale,
or welding splatter.
