S ubstantial quantities of liquid or fluid such as natural gas, oil, water, and emissions are produced every day, all over the world. The quantification of the bulk fluid movement is referred to as the  measurement of liquid flow . A measurement is achieved at every juncture where a transaction occurs. In order to bill the quantity of liquid or gas transfer, a flow meter is regarded to be the most vital device. A brief history of liquid flow measurement The measurement of a fluid holds a huge significance in human civilization since ancient times. The history of the liquid stream measurement dates back to the period when the Egyptians used the current of the Nile as a flow-meter to predict if the harvest would be good or bad. The liquid streaming in the Roman drainage pipes was measured by the orifice plates. Much later in the 50s, owing to the economic production, the use of only orifice flow meter, rotameter, and the pilot tube was profound in the industries. The accu...

Prior to giving conclusions on the best  compact liquid flow meters  for industrial usage, you must understand about them and their applications. The turbine flow meter contains rotor blades positioned on a shaft at an angle. The liquid passing through these blades leads them to turn the rotor shaft. A mechanical reader can sense the shaft’s rotation. In terms of using a clean or corrosive liquid, a turbine flow meter appears to be compact. These types of liquids incorporate water, petroleum, and chemicals. The size of the pipe must not be more than a diameter of 24 inches. Another useful flow meter is a magnetic meter that calibrates the fluid flow through a concept termed as Faraday’s Law. You will not find any moving parts in this meter. Due to its technology and design, a magnetic flow meter can be utilized in a vast range of industrial applications. This meter is capable of measuring the movement of corrosive, abrasive, dirty, and clean water based or other condu...

A vortex flowmeter can be considered to be one of the best flow calibration devices which are highly suitable for liquid flow measurements. These highly significant products are available in an industrial grade, all plastic or brass construction. A delicacy to versatility in the process conditions are not high and without any moving part have comparatively low wear contrasted to other kinds of flowmeters. The operations of the vortex flowmeters usually occur under the vortex shedding rule, where a vibrating vortex occurs when a fluid like water flow past feign (instead of a streamlined) body. The frequency that the vortex is shed at relies on the shape and the size of that body. It’s just perfect for the applications where you give importance to the low maintenance cost. Industrial size  vortex flow meters with pulse output  are tailor-made and need relevant size for particular applications. Vortex flowmeters are made for cost-effective yet accurate mass flow measure...

An instrument, which measures the volumetric flow rate of the fluid running through a closed conduit, is called a rotameter. The device consists of a float and a tube. Being a kind of a variable-area meter, it analyzes the flow rate by the upward and downward motion of the float in the tapered tube and the measurement provided by the flow meter is directly proportional to the area of flow and the flow rate. Principle Involved in the Operation of the Rotameter Now the question is how to read a rotameter?   Rotameter is the most accepted industrial flow meter, which works based on the  principle of gravity  and variable area. The flow rate increases and decreases the height of the float, which accordingly adjusts the passage of the fluid flow and consequently, the total area between the float and the wall of the tube. Equilibrium is reached when the upward force created by the flowing fluid balances the descending force exerted by the mass of the float, hence mainta...

Instruments that are used for measuring the flow rate of a particular liquid, flowing through a pipe, are called flow meters. The measurements can be done based on either the mass flow rate or the volumetric flow rate and the units in which it is measured are kilogram per second and liters per second respectively. The standard liquid flowmeter is used in various fields and has significant utility. In the medical field, industrial sector, like food processing, semiconductor fabrication, water management, etc. There are various types of flow meters, depending on the principle that administers the application. Ultrasonic, Mechanical, Pressure, and Electromagnetic are the types of liquid flowmeters. Open & Closed Channel Flow The flow of any liquid can be classified into open or closed pipe flow. The open channel in the free-flowing stream is not restricted by any wall and the flow is controlled by the force of gravity. The fluid flow in the closed channel occurs due to the p...

A flow meter is a special device that measures the amount of gas or quantity of liquid or its flow rate moving through the pipe. Too little or too much gas or liquid flowing through the pipe may result in the malfunctioning of the machine. There are specific best practices that need to be implemented to receive the most accurate results from your flow meter. These five best practices for calibrating flow meter are: 1: Calibration Standard Proper calibration depends on a standard that is accurate. Thus, the calibration has to be even more precise than the flow meter it will measure. According to industry standards, the rule of thumb regarding calibration standard is, that it has to be four times more correct than the flowmeter that is tested. However, this rule of thumb may adapt depending upon specific requirements of the test. 2: Traceability This best practice is an important and necessary form of documentation. It measures the standard as per which the flowmeter is cal...

Flow meters are the equipment for the accurate measurement of the flow rate of the fluid passing through a pipe or an open space. The measurement can be made either on the basis of the mass flow rate or the volumetric flow rate. The rate of flow can be altered and distributed with the help of particular equipment called the flow control valve sensors. It provides accurate and programmable information, which helps in the execution of the distribution. Various industries have an abundant option of the control valve sensors to choose from. On the basis of the application and the purpose, the type of the sensors are chosen, which gives errorless productivity.   Design of the Flow Control Valves The flow control valve sensors have diversified designs, from simple openings to refined electro-hydraulic valves. These different compositions of the valve sensors enable it to automatically adjust itself according to the change in temperature and pressure. Controlling the Flo...

Different Kinds of Liquid Flow Meters There are different kinds of liquid flow meters, depending on the circumstances in which the flow meters are used.    1. C losed pipe flow meter: The closed pipe flow meter is a type of flow meter that is used for fluids flowing in a closed conduit like sewer, kitchen pipeline, water pipeline, fuel pipeline, etc. and the open channel includes measuring the flow in a non-constricted area.  2. Differential Pressure Flow Meter : Being the most common flow meter in use, it has primary and secondary component. The first component changes the kinetic energy and the second one measure the differential pressure, which produces a signal that can be changed to get the flow rate.   3. Velocity Flow Meters : This flow meter operates directly with the volume flow rate. It translates the data of the velocity of water into its volume. When the flow meter is used with Reynold’s number greater than 10,000, the flo...
