![]() ![]() Positive displacement flow meters gauge a known volume capacity is filled with liquid, transported further and then filled again. Velocity flow meters are used in all major industries for a variety of fluids. Velocity flow meters can be divided into Vortex Shedding, Turbine, Swirl, Electromagnetic, Ultrasonic Doppler, Pitot Tubes, and Calorimetric. ![]() When the flow meter is used with Reynolds number greater than 10,000, the flow meter becomes insensitive to the viscosity change of the fluid. It integrates the data of the velocity of fluid into its volume. This flow meter operates directly with the volume flow rate. It is also used in chemical, paper, mining, pharmaceutical, water, beverage and HVAC (Heating, Ventilation, And Air Conditioning) applications. The most common use of a differential pressure flow meter is within the oil and gas industry. Bernoulii’s equation can be applied where the liquid flow is directly proportional to the square root of the differential pressure produced. A differential pressure flow meter gauge measures the deferential pressure across an orifice or obstruction in the flow path. Here are the 6 fundamental categories of the liquid flow meters.īeing the most common flow meter in use, they can further be divided into Venturi Tube, Orifice Plate, Flow Tube, Flow Nozzle, and Rotameter. What are Various Types of Liquid Flow Meters?īased on the nature of application, the particular liquid and the construction, including material, there a different types of liquid flow meters. The distinction in the functional method and technical aspects is based on their areas of applications, operational values, and nature of liquid that is being measured by them. Available with diverse technical features and mechanisms, the particular application defines the capacity and type of the liquid flow meter. It is used in a number of different applications such as natural sources, pipelines, chambers, tanks, usable industry chambers, etc. A liquid flow meter is an instrument utilized to gauge linear, non-linear, mass or volumetric rate of a liquid flow. Liquid flow meters are utilized to determine the volume of liquid flowing through in order to control critical processes, determine the amount that needs to be billed or the quantity of product being produced. These industries need to know the accurate amount of liquid being flowed through a point. The use of liquid flow measurement is vital is a number of different industries which include semiconductor, medical, power, oil, food processing, metallurgical, water and waste treatment. ![]()
