i am trying to find a way of detecting moving water and air in a pipe.
should the water or air stop flowing then i need to activate an alarm, i am trying to find a way of sensing this movement without costing a small fortune for some sort of sensor.
i have 2 pipes that need monitoring, 1 pumps water (water is always in the pipe, i need to know when its moving)
the other pipe has water in it but also has air being pumped through it, i need to know if the air stops.
any help/ideas etc would be great
