A flow meter is a device that measures the flow rate of a fluid. These valves are used for controlling the air flow or liquid flow. To manufacture these devices, flow meters are used in the machines. There are two basic types of flowmeters: liquid and gas. They offer repeatable & accurate flow measurements for different applications like semiconductor processing, process control, etc. Flow measurement can be obtained by counting the no. The Venturimeter: A Venturimeter is a device meant for measuring the quantity of a liquid flowing through a pipe. Liquid is primarily measured in terms of volumetric flowrate, while gas is a mass-flow measurement because of the unique properties of gases when compared to liquids. Flow meters are also known as Flow Gauges. This type of meter is used to provide an estimated flow rate to the consumer by measuring the volume of the substance flowing through them. Let us have a look at few: • Medical Science: Flow meters are required in Aesthetic devices and medical research.

Modern innovations in the measurement of flow rate incorporate electronic devices that can correct for varying pressure and temperature (i.e. The type of equipment needed for your flow measurement process depends on the type of application and requirements such as minimum and maximum flow rates, the size of the meter required, and material compatibility with your operating environment. Those flow measurement devices can be used up to a maximum pressure of 100 bar and a maximum temperature of 180 °C. Thousand standard cubic meters per second 4. These meters mainly include paddlewheel, turbine, electromagnetic, vortex shedding & sonic or ultrasonic flow meters. Be it heating Ventilation and Air conditioning (HVAC), automotive, marine industry, research laboratories or any other application, flow meters have different scope. If calibration is not done, the devices may show different results from the actual, which will affect the further application. These are very popular due to their simple design & less cost. eLivestory - Startup Stories|Society with World. The article explains what you need to know about the basics of ultrasonic flow measurement and its applications. This requires a lot of technical expertise and engineering knowledge of various flow types as well as commercial experience. Notify me of follow-up comments by email. All Rights Reserved. What are The Applications of Flow Measurement Devices? Also, these devices are in constant contact with the liquids and gases. Open-channel flow occurs when liquid flows in a conduit or channel with a free surface. These meters are classified into four types which include the following. 7 Tips for Using Dog Treats Correctly When Training Your Pup. These types of meters measure the flow of liquid with the help of moving parts arrangement, known liquid volumes through a sequence of chambers or gears. These are classified into different types based on its application like a mechanical, optical and open channel. The work consists of a theoretical part, which describes the principles of flow measurement and, directly, the analysis of the methods and its applications.

While some volumetric technologies can measure gas flowrates, there can be problems with totalized flow. While as many as seven different types of flowmeters can be used to measure steam flow, the vast majority of steam flow measurements are made with differential-pressure (DP) and vortex flowmeters. Many different devices are used for flow measurement depending upon the application: Gas flow meters; Vortex flow meters; Thermal flow meters; Liquid flow meters; Differential pressure flow meters; Magnetic flow meters; Positive displacement flow meters; It is a long list, which keeps on increasing with the rapid increase in the need for different type of measurements. With an increase in market trend in air and water treatment applications, the importance and use of these devices are increasing. • Automotive: In automotive, different valves are manufactured in different systems such as braking systems. © 2021 - eLiveStory. The applications of flow meters mainly include in industries like pharmaceuticals, metallurgy, petrochemicals, home energy, pulp & building. Where can you study psychology in Ireland? density) conditions, non-linearities, and for the characteristics of the fluid. Obstruction Flowmeter. Obstruction or head type flowmeters are of two types: Differential Pressure Type What You Should Know About Email Spoofing Prevention? This is known as 'data logging' . This meter works on incompletely blocking the flow of liquid within a pipe to create a disparity in the static pressure among the up & downstream part of the device. Thus, a check on the accuracy of their work needs to be done. of accepted isolated volumes. In many cases, the flow of mass is the main consideration, particularly in gases selling/buying, chemical reactions, combustion, etc. Thus, these devices must show accuracy, which if not shown, may result in an error in research results and impact the industry. The liquid flow in the pipe can be equal to the cross-sectional area within a meter & the velocity of the liquid flow (Q = A * v). (12) Where, K = Coefficient of losses V = Velocity of flow g = 9.81 m/s2 SOLTEQ® FLOWMETER MEASUREMENT APPARATUS (FM101) Page 11 5.0 MATERIAL AND APPARATUS Material 1) Water Apparatus 1) Flowmeter Measurement Apparatus (Model: FM 101) 5 1 6 2 3 4 7 9 8 1) Manometer tubes 6) Rotameter 2) Discharge Valves 7) 90⁰ Elbow 3) Water Outlet 8) Orifice 4) Water Supply 9) Venturi 5) … The measurement of blood flow and its related parameters have been evolved through a number of techniques involving di fferent p rinciples. Alternate names of this device are flow rate sensor, liquid meter, flow gauge, indicator based on the industry but the working principle is the same. Our direct immersion variants are the ideal flow meters for existing compressed air and gas lines and can be easily installed and removed under pressure via a ½" ball valve. Measuring flow into a reservoir is a common application where open-channel flow measurement comes into play. • HVAC: flow meters are also used for room pressure monitoring and air pressure monitoring in heating and ventilation application.

Flow measurement for liquids, gases and steam. There are several types of flow measurement devices currently in use across the United States by private, local, state, and federal agencies. … Each variable area flowmeter has to be customized to the application, as the viscosity of the fluid being measured might necessitate heavier or lighter floats to maintain accuracy, which is moderate at best. Rivers, streams, canals, and irrigation ditches provide examples of open channel flow. The main benefits of these meters are improving the accuracy, resolution, and precision of the liquid. Flow Measuring Devices: Types of Flow Meters and their Applications Flow Measuring Device # 1. In almost every sector, different measurement devices are used. Flow meters are flow measuring instruments used to measure the linear, nonlinear, mass, or volumetric flow rate of a gas or a liquid. It is of less importance if the pipe through which the liquid or gas flows is straight or any other shape because it is difficult to guess the easy manner. Among the major types of measurement devices used in surface water (open channels) and/or closed Design By. The best example of this flow is rivers, canals, irrigation ditches, streams, etc. Coriolis mass type is the most accurate but it is expensive. Flow measurement devices for wastewater treatment plants may be conveniently divided into open channel and pipeline devices. This liquid can be completely open to the atmosphere or enclosed in a closed tube with partially filled liquid and simply unlock to the atmosphere at the fitting end of the meter itself. Linear feet per minute 5. essential to measure accurately the rate of fluid flow within a system as a whole or in part Some types of meters mainly focus on liquids and gases in a pipe.
