Operation of Advanced Meter Infrastructure Systems

You would come across references to AMI or an Advanced Meter Infrastructure system quite often these days. Such a system comprises a smart meter that is installed at the premises of the consumer, a meter data management application or an MDMA and a communications network between the utility service and the smart meter. The smart meter is equipped to transmit price signals to the control centre within the residential premises. The smart meter is equipped to record and store the data based on hourly consumption, to provide a report of the power supply status and to switch off the power supply of the entire home. A record of the prices and the control signals are transmitted to the smart meter via the communications network that comes with the system. It is also equipped to send relevant information about the hourly electricity consumptions and facts such as whether particular appliances are in use and whether there is continuous power supply to the home. The meter reading systems that have been in use so far are not equipped with this kind of functionality. On the contrary, meter readings are collected once every month. The popularity of the advanced meter infrastructure system can be attributed to the fact that the utilities benefit to a great extent from investments in such a system, especially when it comes to the distribution systems. The labour costs are substantially reduced as there is no need to employ staff for reading meters. The recruitment is centred on employing people for devising and creating such meters and their installation. Most of the advanced meter infrastructure jobs can be...

Basic Operation Of Centrifugal Pump

A pump is a device used to move fluids, such as fluids or slurries. Centrifugal pump is a device for moving liquids and gases. The two major parts of the device are the impeller (a wheel with vanes) and the circular pump casing around it. In the most common type, called the volute centrifugal pump, fluid enters the pump at high speed near the centre of the rotating impeller and is thrown against the casing by the vanes. The centrifugal pressure forces the fluid through an opening in the casing. This outlet widens progressively in a spiral fashion, which reduces the speed of the fluid and thereby increases pressure. Centrifugal pumps produce a continuous flow of fluid. A centrifugal pump works by converting kinetic energy into potential energy measurable as static fluid pressure at the outlet of the pump. This action is described by Bernoulli’s principle. With the mechanical action of an electric motor or similar, the rotation of the pump impeller imparts kinetic energy to the fluid through centrifugal force. The fluid is drawn from the inlet piping into the impeller intake eye and is accelerated outwards through the impeller vanes to the volute and outlet piping. As the fluid exits the impeller, if the outlet piping is too high to allow flow, the fluid kinetic energy is converted into static pressure. If the outlet piping is open at a lower level, the fluid will be released at greater speed. The typical application areas for Centrifugal pump are: Sump emptying, Industrial effluent treatment, Feeding oily water separators, Transfer of ‘live’ fish, Oil and Chemical spillages, Mine Drainage, Parts...

A look at Cataract operation

One good origin for medical professional is technology. For instance, optical lasers are a few of the utmost medical inventions ever produced during the 21st century. They are utilized for a lot of surgical techniques such as cataract surgery and other eye-related procedures. Before, people merely live with cataracts since they did not have any other alternative. Furthermore, it is different at the present and the cataract surgery has offered lots of people to see openly for an extensive period of time. Having cataract surgery is totally great because it gives a feasible choice for many baby boomers who are experiencing bad vision. As they mature, people are triggering cataracts in merely one or both of their eyes. Cataracts are cloudy coverings that can be found over the lens of the eye. Usually, they involve both eyes but some happen over the lens of one eye first. Cataract’s symptoms include a cloudy vision, openness to light or sunlight, inability to distinguish colors, halos around individuals and objects, and a poor night vision. Cataracts are truly dangerous to the eyes and if they are not heald, they can trigger loss of sight. When you experience having some of these symptoms, you must consider acquiring a cataract surgery. Cataract surgery can aid in recuperating your eye vision by getting rid of the cataract from the eye. When the cataract is removed, the vision can return to its typical state. An expert ophthalmologist can get rid of the cloudy lens or the cataract itself by making use of an optical laser. Basically, sound waves can crush the lens and they are eliminated...

The Right Way in Autoclave Operation

Autoclave is a lab instrument that can also be owned by individual and manufacturer. In laboratory this instrument is used to sterilize hazardous microorganisms and others. Sterilization means the destruction of microorganism life including spores, viruses, and others. This instrument must be checked regularly to know whether it is working properly or not. If the steam does not directly contact the hazardous materials, the microorganisms are not destroyed by the autoclaving process. To validate the effectiveness of sterilization process you ought to perform vials test. You need to perform this quality control monthly. You also have to clean the unit regularly depending on the items that have been autoclaved. All items that are going to be sterilized must be placed inside the tray. The tray must be able to handle the items from boiling over, falling, and spilling into the chamber. Make sure that the items that you are going to sterilize are autoclaveable. Pay special attention to hazardous liquids. The vessel must be twice larger than the liquid inside. This is to prevent spilling when the liquid is boiling inside the chamber. The caps must be loosened to prevent vessel breakage. You have to put garbage inside autoclave bags and trays of 5 inch sides. Autoclave is an instrument that has a risk in usage. This instrument generates a lot of energy in the sterilization process. There are many possibilities of injury that can happen to the user. To prevent the possible injury caused by the incorrect usage of this instrument, you have to follow the steps below. 1. Wear apron, gloves, and glasses to handle hot vessels....

Operation Kitchen Makeover

The modern kitchen traces its roots to the invention of the stove, along with the technological advancements made in the areas of plumbing and piping systems which made water accessible inside the house. An open fire used to be the only means by which food could be cooked before the stove was invented in the 18th century. Food heating technology improved further in the 19th century, which contributed to the evolution of the modern kitchen as we know it today. The kitchen is an important part of our house. Even the most beautiful house with the most luxurious furniture and fixtures and the most modern appliances would look dreadful if it has a hideous kitchen. Hideousness does not only pertain to the visual appeal of your kitchen. It also has to do with the arrangement of your cabinets and appliances relative to each other and the layout design. If you are unhappy about your kitchen, there is a way to fix your problem: remodeling. The U-shape, L-shape, double L-shape, Galley design, peninsula kitchen, G-shape, Island kitchen, and straight kitchen are among some of the most popular designs used in constructing a kitchen work triangle. This would depend on the size of your kitchen, of course. An interior decorator or a kitchen remodeler will walk you through the most suitable design for you depending on your needs, the traffic in your kitchen, and so on. If you have a medium-size kitchen, a galley type remodel (Minneapolis) would give you the space you need to move freely because the kitchen cupboards are organized systematically. An assortment of kitchen cabinets can be...
