The main characteristics of thermal sensors are. Inferential type flow meters. Flow measurement pdf 1.

Velocity meters consist of turbine vortex shedding electromagnetic and sonic designs. Fall under electrical type flow meters. Cryogenic flow metering techniques 1.

Flow meters are classed as volumetric or inferential the latter term referring to meters that determine velocity from other variables such as pressure differences across a device such as an orifice plate. 1827 Types of Flow Meter. 23 Venturi Flow meter The venturi flow meter while considered an obstruction flow meter is less of an obstruction than the orifice type.

Orifice Plate or Orifice Meter 4. WHAT ARE FLOW METERS THEIR MAIN TYPES. There is a large variety of flow measurement device using numerous physical principles.

Principle of operation consists in applying effect of transfer of thermal energy with using a movable flow. Of the system operations. Acoustic flow meters based on Doppler effect 5.

It mea-sures the differential-pressure drop across a constriction in the flows path to infer the flow velocity. The most diverse substances are transported and distributed in piping system in every single day they may include solvents chemicals oilgas drinking water fruit juices slurries etc The fluid flowing through. The most popular type of heating method is electric.

Flow meters are broadly classified as. Basic Flowmeter Principles How They Work Flowmeters are used in fluid systems liquid and gas to indicate the rate of flow of the fluid. An orifice flow meter Figure 1.

Electromagnetic flow meter Ultrasonic flow meter Laser doppler Anemometers etc. The Pitot Tube 3. Common types of differential-pressure flow meters are the orifice the pitot tube and the venturi tube.

Pitot tubes and fan air inlet cones are also in. Differential-pressure flow meter This meter operates based on Bernoullis principle. It still does have a certain amount of pressure drop but it is significantly less than the orifice type meter.

This interaction may be that of imparting motion to the. Thermal flow meters are used to work with gases and liquids. And every type of flow meter can be assigned to one of two categories.

The following list shows some of the popular flow meter types. The following points highlight the five main types of devices for measuring of flow in pipes. Other meters using this basic principle include wedge and target meters.
