Liquid Flow Meters: Types and Benefits

The constant advancement in science and technology has explored several scopes of facilitating industrial processes at a large scale and Liquid flow meters are one of these endless inventions. These are highly beneficial in measuring the flow of liquid from one source to another. Liquid flow meters are available in different forms with varying technical features and working process, depending upon the area of application and nature of liquid. The instruments are known for their operational benefits in several industrial fields like:

  • Petrochemical industries
  • Chemical industries
  • Food and beverage industry
  • Pharmaceuticals industry
  • Paints, grease and coating industry
  • Oil industry
  • Fuel industry

The multiple benefits of liquid flow meters have added to the various significances of these devices. The following are the major areas of application:

  • Flow meters are used in a variety of industrial sectors in order to analyze the amount of usage of certain liquids and the velocity of the same.

  • In many cases, liquid flow meters are used to assess the total consumption of water in a particular area by households within that area.

  • It also helps in detection of leakage of liquid and thereby saves it from wastage.

  • Flow meters control and direct the flow of the liquid and regulate the velocity of flow in order to maintain a favorable pressure level.

  • Liquid flow meters are made to withstand the inconsistencies of nature and hence provide complete benefits in the form of accurate data irrespective of variations in environmental temperature or pressure.

The following are the types of Liquid Flow Meters available in the market:

A)  Differential Pressure Flow Meters

  1. Orifice Plates
  2. Flow Nozzles
  3. Venturi Tubes
  4. Variable Area (Rotameter)

B) Velocity Flow


  1.  Pilot Tubes
  2. Calorimetric Flow Meters
  3. Turbine Flow Meter
  4. Vortex Flow Meter
  5. Electromagnetic flow Meter
  6. Ultrasonic Doppler Flow Meter

C) Positive Displacement Flow Meters

  1.  Reciprocating Pistom Meter
  2.  Nutating Disc
  3. Meter
  4.  Rotary Vane Meter

D) Mass Flow Meters

  1. Thermal Flow Meter
  2. Coriolis Flow Meter

 E) Open Channel Flow Meters

To put it all together, liquid flow meters not only measure the flow of the fluids, but also make sure that the same is not wasted or over used due to leakage or uncontrolled velocity. These devices facilitates in forming accurate data about the total consumption and usage of the fluids or liquids for different applications.
