1. A ______________is a differential pressure flow sensor that constricts the flow through a contoured plate.

2. The smooth transition provided by the flow nozzle creates less on the high-pressure side than an orifice plate.

3. The most accurate differential pressure flow sensor is the ______________ which has smooth transitions on both sides of the restriction.

4. ______________ flow sensors are among the oldest types of sensors.5. Fluid flow through the nozzle on a pitot tube creates both impact pressure and

______________ pressure.6. A ______________ is a section of pipe with a tapering inlet that contains the high-

pressure tap, a tapering outlet, and a cylindrical constriction in the middle that contain the low pressure tap.
