Benefits of Liquid Flow Meters

As technology advances and new industries are developed, the need for precise and exact measurements only increases. Liquid flow meters are one such innovative tool created to meet this need. Continuous development of these instruments has served the advancement of many different industries and an ever-increasing range of applications.

True to its name, liquid flow meters measure liquid or gas flow through a pipe and its rate of change. Different types exist with varying construction to serve a wide range of purposes; however, each are built to the best possible fluid dynamic principles. Important technical features and type of meter used generally depend on the viscosity, temperature, etc. of a liquid and the area of application.

Benefits through Wide-Range Applications

Today, liquid flow meters have cemented themselves as essential instruments used in many different industries. Some of these industries are:

  • Fuel and Oil
  • Petrochemical
  • Chemical
  • Pharmaceutical
  • Paints, Grease, and Coating
  • Food and Beverages

Outside of industry use, liquid flow meters are used for educational purposes in university science and engineering programs. They are also used in housing projects to track the amount of water utilized.

Engineers have created liquid flow meters that can withstand extreme variable such as outdoor temperature and pressure; regardless of the weather conditions, we have developed meters that give accurate results. Control valves are often used in conjunction with these instruments for the extended application of directing the fluid and normalizing velocity, hence maintaining the required pressure level.

Use of liquid flow meters have benefits outside of measurement, such as helping to control the velocity of a fluid and its use. They can also save water from being wasted by detecting leakage in pipes.

Benefits of Liquid Flow Meters Particular to Type

As already discussed there are many types of liquid flow meters. Some of the most widely used are Electromagnetic Flow MetersUltra Sonic Flow MetersCoriolis Mass Flow Meters, Thermal Mass Flow Meters, Differential Mass Flow Meters, Variable Area Flow Meters, Turbine Flow Meters, Vortex Flow Meters, Swirl Flow Meters, Venturi Fumes, Oval Gear Flow Meters, Oscillating Piston Flow Meters, Weirs, and Lobed Impeller Flow Meters.

Of the most commonly used, here are some key benefits and advantages.

Differential Pressure Flow Meters:

  • Suitable for gas and steam measurement
  • Low pressure drop for nozzles

Coriolis Flow Meters:

  • Accurate measurements of mass flow
  • Additional measuring capability of density and temperature
  • Self-draining
  • Allows bi-directional flow of liquid
  • Set measuring range according to flow rate and density

Ultrasonic Flow Meters:

  • No moving parts
  • Concentration, temperature, and density doesn’t affect the transit time meters
  • Low maintenance
  • No extra pressure drop
  • No obstructed flow channel

Thermal Mass Flow Meters:

  • Extreme accuracy in measurements
  • Quick response time
  • Directly measures gas flow
  • Easy sterilization

Turbine Flow Meters:

  • Rotating Vane and Woltman meters require no auxiliary power
  • Bears high pressures and temperatures
  • Appropriate for cyrogenic liquids
