Installation
Before initial installation:
Please rinse the unit with clear water or the medium to be measured before the initial
installation.
Read the following information and have a thorough understanding before proceeding with
meter installation. Only qualified personnel should perform meter installation.
Install a strainer or Y or basket as close to the inlet side of the meter as possible.
Strainers prevent dirt and other fluid contaminants from impeding meter performance.
Strainers require periodic cleaning, as clogged strainers also impede
meter
performance. Contact your local representative for specific information, per
your
specific application.

Turn off any associated pumps to reduce line pressure and slowly fill the line and
meter with fluid before restarting pumps. Doing so reduces the possibility of meter
damage caused by errant air pressures in the line and meter.
Make sure all pipe conforms to the same pressure output rating as the pump.
Make sure to apply thread sealant to all pipe threads.
Make sure to install the meter as shown in figure 1.
Check for and repair leaks upon initialization of fluid flow.
