How does a Liquid Flow Meter Works and What are Its Applications?

In simple words, an instrument that measures the rate or velocity at which liquid or fluid moves through a structure like pipelines or similar carrier, is called a liquid flow meter.Liquid flow meters can measure volumetric and mass flow rate, wherein the volumetric flow rate is measured in cubic meters/second and the mass flow rate is measured in kilograms/second.

What is the Process Involved in Measuring Liquid Flow Rates?

Apart from measuring the flow rate, a flow meter also detects the precise amount of liquid present in the pipelines or other structures. These liquid flow meters are widely used for a gamut of applications (domestic, industrial, and commercial), wherein they monitor, measures and assess the existing amount and flow rate of the liquid.

Let us know how it works. In order to achieve accurate fluid measurement, the flow meters are placed near the feed lines and the meter boards display the accurate results of the flow rate. Although the common units used to read the measurements are ‘cubic feet’ or ‘inches’, the units may vary from one device to another depending on its specifications. The results are displayed in straight or circular registers, and each register comes with a numeric pattern that calculates the total usage of water.

Usages and Applications of Liquid Flow Meters

These flow rate measurement devices monitor and assess the amount, flow and usage rate of the liquid or fluid matter in pipelines, and this leads to proper fluid management. At the same time, the process also detects if there is any misuse or leakage leading to wastage. When it comes to measuring the flow or amount of liquid in specific containers like pipelines, tanks, industrial chambers, and natural sources, liquid flow meters are the most common and effective device.

Industrial liquid flow meters can possess varying mechanisms and technicalities, and their operational modes and features depend upon their applications, functionalities, and the nature of liquid. The following are the industrial sectors where liquid flow meters are used:

  • Food and Beverage
  • Petrochemical Industries
  • Water Research
  • Fire Rescue Operation
  • Chemical Industries
  • Pharmaceutical Industries
  • Oil Industries
  • Fuel Industries
  • Paints, Grease, and Coating Industry
  • Sub-Marine Industry

As a customer, it is important to know that different types of liquid flow meters are used for varying applications. Hence, the foremost factor to know is the kind of application for this device. The different kinds of flow meters present in the market are differential pressure flow meters, mass flow meters, velocity flow meters, positive displacement flow meters, and open channel flow meters.
