How to make a display of water flow in the pipe on the avr?

Good day fellow dostarczane, the problem is a water pump(stupid piece of hardware which is nothing but to pump the water can not), somehow without interfering with the system(read: not navarivaya anything extra on the pipe) necessary to determine that the pump is faulty(if anything), I stopped by the NAT to check for leaks in the water in the pipe, but I've no idea, suddenly someone on your mind is

The decision "in a forehead" - the flow switch liquid. The rest is dancing with a tambourine.

If you do not intervene in the system only the ultrasonic sensor, but it is difficult and expensive. Cheaper mechanical gauge, but it must be built

Put after pump home water meter. They have a reed switch inside and a known number of pulses per cubic meter.

Maybe we should control water, and the current consumption of the pump?

Can noise passing(current) of water....

the motor current of the pump and the temperature at the inlet and outlet, as indirect indicators, but it is safer to put the pressure sensor at the outlet of the pump or flow switch if performance is small.
