Hi,
I am new to this forum and the subject of MEMS, so please bear with me
if I don't have my terminology right.
I have some questions about miniature pressure sensor :
We need a sensor which can detect the change of the fluid level above it
when the container is moving and the fluid in the container is swishing
around.Are  there pressure transduces which are fast enough to detect
the instant change of fluid level above it at a level of a few (4-8)
inches of water  ?

At the same time we want to sense the fluid temperature, density and
dielectric constant.

Your help would be very much appreciated.

In an other application we need to detect the presence of ferro magnetic
particles in a process fluid. Optical methods cannot distinguish between
the metal particle and other fill particles.
Is there a miniature magnetic field sensor which could be adapted to our
application ?

Again, thanks for all the help,

Lillie
