## Questions & Answers

**Q: If air is flowing through the sensor will it sense? I want it to be use for sensing water only**
A: Can it detect  the direction of flow

**Q: How much voltage does it require? And can it stop water flowing through a tap like solenoid valve?**
A: 5-24V  working voltage.Yes we can stop water flowing through solenoid valve using any controller like PLC

**Q: can i use for 1/4" tube of water purifier, so that i can measure water flow**
A: Yes ,you can use it. If you want the programm for counting & storage of data -I can provide that.

**Q: How to calculate flow??**
A: As per the Achilles Heel of any water system - Flow rates are measured in gallons per minute (gpm). Considering standard velocity of water as 8 feet per second -the flow rate for different diameters of pipe will be as follows:1/2" = 8gpm / 1" = 21gpm / 1 1/2" = 46gpm / 2" = 80gpm and so on.The flow rate may vary depending on the type of piping we use.
