Is the most common method used in industry.

• Differential Pressure Flow Measurement

• Differential Flow Measurement

• Pressure Flow Measurement

• Differential Pressure Measurement

For ___ always mount the D/P cell below the orifice plate to ensure the sensing lines.

• LIQUID SERVICE

• GAS SERVICE

• PITOT TUBE

• VENTURI TUBE

The _____ is the static pressure of the pipe and the impact pressure in the tube.

• DIFFERENTIAL PRESSURE

• PITOT TUBE

• VENTURI TUBE

• FLOW NOZZLE

It is a bent hollow tube with the point facing upstream in a pipe.

• PITOT TUBE

• DIFFERENTIAL PRESSURE

• VENTURI TUBE

• FLOW NOZZLE

A typical application is High flow rates of superheated steam.

• TRUE

• FALSE

Answer explanation

It is because the nozzle itself can have many different shapes as determined by the manufacturer.

The Disadvantages is the higher cost and the fact that it is difficult to maintain or replace.

• TRUE

• FALSE

The inlet angle is

• 19-23

• 18-24

• 17-21

• 19-21

There are many advantages to the Venturi tube except one:

• More accurate than the orifice plate

• 0.5-3% lower pressure drop

• Higher measuring flow rate than the orifice plate

• The pressure is lower than its actual raint

Before the device used to measure flow by the differential pressure method can be studied, a good understanding of ______________ is required.

The ______ is an elongated pipe that is shaped like the vena contracta flow pattern.

• VENTURI TUBE

• VENTURE TUBE

• VINTURI TUBE

• VENTORI TUBE
