Anemometer instrument Britannica

With modifications, it can be used to measure supersonic air flow. Another type of pressure anemometer is the Venturi tube, which is open at both ends and of larger diameter at the ends than at the middle. Airspeed is determined by measuring the pressure at the constriction in the tube. Venturi tubes have some applications in industry.(pipe) Basics of Venturi Flow Meter - InstrumentationTools(steel) Essential upstream pipe length of a venturi tube is 5 to 20 diameters; Venturi tubes exist in sizes up to 72. A venturi tube can pass 25 to 50% extra flow than that of an orifice plate keeping the same drop in pressure. Since, the early cost of a venturi tube is quite high, it is mainly engaged on larger flows and in more complicated or challenging flow applications.(pipe) Daniel Venturi Tubes Emerson US(steel) Measurement Type Differential pressure Fluid Type Gas, liquid hydrocarbons, air, water, vapor, steam, sludge, slurries Discharge Coefficient Uncertainty Uncertainty ±0.25-0.50% Line Size 2-in to 72-in (50-mm to 1830-mm) Max.

The flow measurement instruments show students the common methods of measuring water flow. They also give applications of the steady flow energy equation (Bernoullis equation). Students use a Venturi meter and an orifice plate meter and compare the losses of each. They also find the losses in a rapid enlargement.(pipe) Flow Meter Types Based on Measurement Techniques(steel) Flow meter is an instrument used for the measurement of the amount of liquid, gas or vapor that passes through them. In some flow meter the flow is measured as the amount of fluid passing through the flow meter during a time period (such as 100 liters per minute) whereas other flow meters measure the totalized amount of fluid that has passed through the flow meter (such as 100 liters).(pipe) Flow meter device Britannica(steel) Flow meter, Device that measures the velocity of a gas or liquid.It has applications in medicine as well as in chemical engineering, aeronautics, and meteorology.Examples include pitot tubes, venturi tubes, and rotameters (tapered graduated tubes with a float inside that is supported by the flowing fluid at a level that depends on the flow rate).).
