5. Meter installation
Read the following information and have a thorough understanding before
proceeding with meter installation. Only qualified personnel should perform meter
installation.
• Install a type 60 mesh 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.
• Install the meter along the meter shafts in a horizontal plane (see figure 1).
• Check for and repair leaks upon initialization of fluid flow.
6. Meter operation
Fluid enters the inlet port and then passes through the metering chamber. Inside the
chamber, fluid forces the internal gears to rotate before exiting through the outlet port.
Each rotation of the gears displaces a specific volume of fluid. As the gears rotate, a
magnet on each end of the gear pass a reed switch in the top-mounted register's circuit
board. The reed switches send pulses to the microprocessor in the register to change
the LED display segments.
