Partially-Filled Pipe Situations
In some locations, the process pipe may be momentarily only partially filled Examples include: lack of back pressure,
insufficient line pressure and gravity flow applications
To eliminate these situations, do not install the meter at the highest point of the pipeline

Do not install the meter in a vertical, downward flow section of pipe
Always position the ON/OFF valves on the downstream side of the meter

To minimize the possibility of partially-full pipe flows in horizontal, gravity or low pressure applications, create a pipe
arrangement that ensures the detector remains full of liquid at all times
