## Questions & Answers

**Q: will it or can it detect smallest movement of water flow in a pipe?**
A: Sorry, we are afraid that the ultrasonic leak detector is unable to detect smallest movement of water flow in a pipe.
this air leak detector is tested by ultrasonic. The ultranosic is broadcast through the air.

**Q: Necesito detector de fuga de agua debajo del cemento**
A: Sorry, the leak detector is tested by ultrasonic. The ultranosic is broadcast through the air. If you want to use it to test the water leak detector under cement, I'm afraid it can't be detected.

**Q: Can you detect a water leak in a pipe under concrete floor?**
A: Sorry, it can't detect under concrete.

**Q: Would this work for low pressure vacuum hose in a car emissions system?**
A: This system works by sending out an ultrasonic frequency sound and using the receiver to pick up this signal.  I used my unit to check for water leaks in my car.  I put the transmitter inside the car near to the leak and used the receiver to check for the generated sound outside and around the door seals of my car.  A leak would require an opening in the car's seals and this should allow the sound to get through to be picked up by the detector.  It is unlikely that the sound that you are interested in would be detected by this unit.
