The Most Common Flow Meter Types |
Posted: July 18, 2019 |
Flow measurement is crucial and critical to most industries, for example, water and waste treatment, power, and oil. These different industries, for the most part, require that they have knowledge precisely how much fluid is traversing through a point at a given period. Flow meters or flow indicators aid in determining how much money must be charged or the total number of products produced. A flow meter is a device utilized to calculate or compute non-linear, volumetric, mass, or linear flow rate of a fluid. A lot of flow meters function by pushing flow through a certain constricted space and calculating various properties to identify the flow rate of a liquid or gas. Examples of computed or calculated properties include magnetic, thermal, pressure, etc. There are a lot of flow meter types available today. For a little help, here are the most common flow meter types. Read on! History and BackgroundOver the years, discovering flow has been, for the most part, quintessential to human development and culture. A long time ago, the Egyptians utilized the Nile River’s flow to know how well their crops for the year was going to go. Understanding and awareness of the velocity and direction of both water and air helped early communities and ancient navigators in their creation of an artificial channel for conveying water. Recent advances and new technologies have increased the accuracy and practicality of all flow meter types. In this generation, flow meters can now change their range between two distinct calibrated times. These technologies and advances are, for the most part forecasted to continue to advance and evolve flow meters in the long run. Flow Meter TypesThere are a lot of measuring devices in the market today and each flow meter type functions in the best way possible under various conditions. The essential and vital part of selecting a flow meter or flow sensor is to have a comprehensible understanding of the requirements of a certain application. Some great questions that can aid you in determining the flow meter type needed for various applications are; what kind of fluid is being calculated, what’s the presumed temp of the fluid, what’s the expected maximum pressure at the area, how precise or exact must the flow meter be, will the flow be sporadic or continuous, what flow range will the system be governed by, and lastly, what’s the size of the pipe the flow sensor will be mounted on? These questions will be, for the most part, very crucial when you decide which meter must be used in various applications. Differential Pressure Flow MeterThis flow meter type functions by establishing a constriction in the cross-sectional portion of a flow. Constricting the flow area triggers a pressure drop all over the restriction, this pressure drop is, for the most part, generated by a modification in the velocity of the fluid. The working principle is founded on the continuity equation of fluid flow and the Bernoulli equation, merging or integrating these equations, you can discover the relationship between the pressure drop and flow rate. The most common DP flow meter types are orifice plates, flow nozzles, venturi tubes, and rotameters. Positive Displacement Flow MeterThis flow meter type is the only flow sensor that directly calculates or compute the volume of fluid traversing through a pipe. It is attained by conveying a particular amount of fluid with each spin of the flow meter, an excellent analogy on how PD flow meters work is to think about filling a bucket and unloading it a couple of times to calculate the total amount of water. This flow meter type is very precise regardless of the temperature, velocity, density, and viscosity of the fluids. Since it is easy to use and its accuracy, positive displacement flow meters are, for the most part, generally utilized for domestic water calculation. The common types of PD flow meters are piston flow meters, gear flow meters, and helical flow meters. Open Channel Flow MeterOpen channel flow arises when a component of the flowing liquid is unenclosed to the open surface. Since the cross-section portion of the flow is identified by the depth and shape of the pipe or channel that the fluid is traversing through, this lack of consistency in the area makes it hard to measure the flow than fixed area flows, for example, pressurized pipe flow. The most common types of open channel flow meters are flumes, weir, and sluice gate. TakeawayKeep in mind that flow is of various types. Each flows with multiple properties relying upon its viscosity, the kind of medium wherein it’s moving, and other qualities have caused the technology of flow meters to a different horizon. And all industries, such as gas and oil, need to know how much fluid is traversing through a point at a given period, making flow measurement critical to many industries.
