Free’ Gas and Electricity Smart Meters Not Actually Free | Good Morning Britain

The new gas and electricity ‘smart meters’ are being advertised as ‘free’, which isn’t exactly true.

Save Money and the Environment with Electricity, Gas and Water Meters

Household attitudes to energy conservation and the environment vary considerably. Whether it’s due to people purely not caring, not having enough time, being miss informed or through laziness that they don’t recycle or do not do not conserve energy resources for example.

Saving energy and conserving water in the home are very easy practices but with plentiful water and electricity on demand, we often forget these are not sustainable resources and do cost money.

The economic downturn has hit just about everyone. Of course is varying amounts but what each and every one of us are noticing is the rise in fuel bills especially during the last two harsh Winters experienced in the United Kingdom. Monthly bills can be seen, the rising costs month on month felt.

Whatever way a household conserves and saves energy and water is good and for whatever reason. If the honest reason is not due to environmental reasons then that isn’t all bad, resources are still being saved at the end of the day. For example, replacing an inefficient shower head with a high flow rate to a water efficient one could save a family of four in the region of £50 off their gas bills and around £75 off their water bills each year. That is a quite considerable saving of both resources and money. And why waste time waiting for a full kettle of water to boil when only a cup full is required. Only filling the kettle with the amount of water required saves electricity, water and time.

An easy way to monitor and save electricity, gas and water is by installing meters. Water, electricity and gas meters installations are on the rise with households and businesses wanting to monitor consumption which in turn, helps achieve lower bills. Electricity usage can be tracked to find out when and with what products use the most energy. These pieces of equipment or appliances could be used in a different way to lower energy consumption or may be even replaced with more energy efficient items.

Gas, water and electricity meters are quick and easy to install alongside an existing circuit or gas system various different models can be found to suit different household requirements and set ups.  A brief summary of the main types of household gas and electricity types can be found below:

Pulse Output – A pulse output is a relay contact (more often that not an electronic relay) inside the meter that closes momentarily when the meter advances it energy register. By connecting this up to either a BMS (building Management System) or an Energy management system the remote equipment can count the pulses and in turn display the same reading as the meter remotely.

Communications – Unlike pulses with a more intelligent system where a dedicated communication protocol is used, the meter is asked by the remote system for the readings out of its internal registers. This means that if the meter fails to respond then an alarm can be raised straight away. Not only that but any register/ value in the meter can be read remotely such as current, voltage, power factor, frequency, instantaneous power as well as the energy register displays.

Analogues Outputs and Alarms – Some Electricity Meters have analogue outputs which can be programmed to give a 4-20mA or similar in sympathy with the amount of instantaneous power being consumed. Other Electricity Meters have alarm outputs which can be programmed to signal various conditions.

Diaphragm Gas Flow Meters – These gas meters are the cheapest way of monitoring gas usage. We are able to supply these gas meters with or without a pulse output which would be used for connection into a building management or energy management system for remote data collection and reporting.

Turbine Gas Flow Meters – These gas flow meters are more expensive than the diaphragm variant. They also come with a battery powered electronic display and pulse output which would be used for connection into a building management or energy management system for remote data collection and reporting. These meters would generally be used for natural gas applications although some can be used on pipe work carrying different gases.

So the combination of thought and the installation of gas, water and electricity meters, a household can keep on top of bills, costings and their respect for their precious environment.

The Primary Functions Of Electricity Meters

A power monitor, or electricity meter, is a device that is primarily used for measuring the energy consumption of a household, business or an individual appliance. Electricity meters typically use the kilowatt hour as its unit of measurement. These devices may be installed by the consumer or a utility.

How Do They Work?

Modern electricity meters operate continuously to give an accurate measurement of instantaneous voltage and current. It calculates the product of the voltage and current to come up with the total instantaneous output. That figure is then integrated with the factor of time to find the final energy consumption figure.

What are the Different Types?

There are two basic types, or classifications, of meters. The most common is the electromechanical meter, which was invented in 1888 by Elihu Thomson. Its operation is rather uncomplicated, involving a simple calculation of how many revolutions an aluminum disc inside the meter actually makes. The rotation of the disc is proportional to the speed of the power used. The second type is the solid-state meter. This device is equipped with an LCD that displays the electricity usage. It is also able to record several other parameters.

What are Their Different Uses?

Other than simply measuring the energy consumption of a home or appliance, electricity meters also have other functions. For instance, if a household or business wants to cut down on electricity costs, they can refer to these devices periodically to identify which appliances use the most electricity. Some households even use individual electricity monitors for each one appliance they have in their home. Meters are also used to check if an appliance is as energy-efficient as its manufacturer claims it to be. Energy monitors can also determine what time of day electricity is used the most.

Who uses These Devices?

Utilities use a customer’s power monitor as a basis for the customer’s bill. Typical monitors have the basic feature of logging the amount of electricity a home or office is consuming. Utilities then send meter readers to an address to record and interpret the amount of kilowatt hours of electricity the address has used.

On the other hand, there are also monitors that are able to send usage details and other relevant information to the utility remotely. Time and usage statistics supplied by these devices are essential for energy plants, and are used for the purposes of output management and billing. The end consumers, like households and business enterprises, also use these meters to monitor their electricity usage, as well as for an assortment of other purposes.
