General questions regarding pressure sensors , needed equipment

  1. Feb 23, 2010 #1

    Working on a rather large project and it's the first time i've had to look into the world of pressure sensors.

    Basicly, we're looking into measuring flow levels in small rivers, either in areas where we build a profile to gather up the water and in natural areas where there's no need for construction.

    Most of it seems to be pretty straight forward, but there's a couple of things i'm struggling to fully grasp

    What type of equipment is needed for submerged pressure sensors ? Is it pretty much a case of getting it to the bottom of the river and fasten it there by using your own preferred method ?

    Is there any point in using a differential pressure sensor in rivers ?
    Basicly been looking at absolute pressure sensors and gauge reference pressure.
