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 .

Do not install in a vertical, downward position . Position "On/Off" valves on downstream side .

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 .
