Subject: Tiltmeter as Horizontal Seismometer

I am drafting plans to build a three electrode spirit level style tiltmeter to use as a 
horizontal seismometer.  Any hints on construction?  What liquid is best?  Are 
surface tension and/or viscosity critical?  

I'm planning on using a Wheatstone bridge detector circuit.  Can this be improved?

Thanks for your comments.
