Troubleshooting

Liquid content problems



Multiple liquid contents do not comply accurately to expected sound speed criteria.



Very hot pipe almost turns water to steam and therefore exhibits the wrong speed
characteristics –could be due to reduced pipe pressure.



Flashover – liquid turns into a gas because of lower than required pressure.
