Liquid Flow Meters and Switches

What is die casting? Die casting is a specific manufacturing process that produces sharply defined, accurately dimensioned, textured or smooth-surfaced metal parts. It relies on metal casting; a technique that forces molten metal under extremely high pressures into reusable mold cavities (also called metal dies).  Mould cavities are made using two toughened steel dies which are machined into a particular shape. They operate similarly to an injection mould. A majority of die casting are manufactured from various non-ferrous metals such as copper, zinc, aluminum, lead, tin-based alloys and pewter. The type of metal that is casted will determine whether a cold or hot chamber machine is used. The process of die casting is sometimes explained as the nonstop route between a raw material and a finished product. “Die casting” may also describe a finished part. What role do flow meters play in die casting? In die casting, a flow meter may be used in two situations: die cooling and o...

In today’s economic environment, energy usage has become a huge concern, particularly on energy efficiency and using flow meters to guarantee accuracy in energy measurement. The upsurge in energy usage demands industries and end users to measure energy usage as accurately as possible. In chilled and heated water applications, the installation of a temperature and flow-measuring device is required. Linked to a BTU computer, the data enables end users to determine how energy is being used, where and how it is used and take steps towards improvement accordingly. However, there are certain limiting factors, which can affect the accuracy of flow meter systems. The following is a discussion on various technologies that can be used to improve flow meter accuracy: Temperature Sensory Accuracy Let us take an application from matched-pair temperature-sensing technology. It is accurate to (+/-) 0.01% of span (0.02 F). The accuracy of both sensors combined is around 0.04...

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...

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...

Flow meter is an instrument that is used to gauge the flow of gasses or fluid through a pipe. Flow measurement applications differ extensively on the conditional benchmarks, situational limitations, and engineering requirements.  It is crucial that you choose the right flow meter or a flow switch. Every application needs a different combination of the flow meter and switches depending on various factors listed below. Type of readings required  The type of fluid or gas to be measured Temperature of the fluid or gas Inertness between the flow meter material and the fluid or gas passing through it Viscosity of the fluid or gas Pressure vs. Resistance Before you rush to buy a flow meter, it is very important that you first study the fundamentals of the fluid or gas that flows through the system. The properties of fluid or gas would determine the kind of flow meter that should be installed. The equation between pressure and resistance is closely related to the v...
