Installation
Horizontal installation
For horizontal installation, the preferred orientation is to have the electronics installed to the
side of the pipe. In liquid applications, this ensures any entrapped air or solids do not strike the
shedding bar and disrupt the shedding frequency. In gas or steam applications, this ensures that
any entrained liquid (such as condensate) or solids do not strike the shedder bar and disrupt the
shedding frequency.
High-Temperature installations
Install the meter body so the electronics are positioned to the side of the pipe or below the pipe
as shown in Figure 2-2. Insulation may be required around the pipe to maintain an electronics
temperature below 185 °F (85 °C).
Steam installations
For steam applications, avoid installations such as the one shown in Figure 2-3. Such
installations may cause a water-hammer condition at start-up due to trapped condensate. The
high force from the water hammer can over stress the sensing mechanism and cause permanent
damage to the sensor.
