How to measure the water pressure in a pipe?

[tictac]

Hi
I want to measure the pressure of water that moves in the pipe.this pipe is made of plastic.and have a pressure at this range(3 bar to 4 bar)
how can I measure the pressure with out any deformation of the pipe.which sensors is the best?
how does the sensor place inside the pipe to measure the pressure?
by regards,

Re: measure the pressure

you can use the straingauge, then you will need interface with ADC, then the MCU.

Strain gauge? Doubt it. A strain gauge attached to a surface of standard pipe will be very insensitive.
