Various types of Flowmeters.

There are numerous different kinds of flow meters used to determine the flow and velocity through pipes. Most flow meters are classified into one of the following five categories: Liquid Flow Meters, Vortex Flow Meters, Paddle Wheel Flow Meters and Piston Flow Meters. Despite the fact that they are all flow meters and will have a reasonably similar function, but they all end up with a different outcome and purpose.

Liquid Flow Meters

Liquid flow meters are created solely for the purpose of measuring the flow of a liquid. However, there is a big difference in the jobs that a liquid flow meter can be used for. They can be used to measure something as small as the pipes in a cooling system as the pipes in a cruise line ship. Liquid flow meters are commonly used for water and other liquids sharing similar characteristics as water.

Vortex Flow Meters

Vortex flow meters are used to measure the flow of water (liquids) and gases. Vortex flow meters are usually calculated using a computer or machine. The main function is to measure the volume flow, which would be a result of the pressure and temperature sensors readings.

Paddle Wheel Flow Meters

The paddle wheel flow meters measured the flow of water using an impeller and paddles which rotate by the flow of liquids. As a result of measuring the velocity of the waters, these meters would then calculate a volumetric reading.

Paddle wheel flow meters are commonly used in:

  • Irrigation systems
  • Clean water applications
  • Impure water

Piston Flow Meters

Piston flow meters are usually used with corrosive liquids and lubricants. Piston flow meters are intended to monitor the flow of lubricants to drills, mills, gears and other equipment. Piston flow meters are commonly used with other valves and control devices. A couple or automatic, but there are manual controlled flow meters as well!
