London launches the largest LED lighting replacement project to date

London has recently launched its largest street lighting modernization project to date, with plans to replace approximately 35,000 of its 52,000 lamps used throughout the city's street lighting with energy-efficient LED lights by 2016. The project also includes a new control system for remote control of lighting levels based on traffic flow and road usage.
The cost of the first phase of the project is estimated at £1.09 million, but at the same time it can bring about €185,000 in annual energy savings and 9,700 tons of CO2 emission reductions.
Transport for London said it had successfully piloted the Thames Upstream Tunnel in 2011 before the project started, which became the first linear LED lighting tunnel in the UK and reduced 60 energy consumption while reducing maintenance costs. . The management system in the project was also commissioned in Birmingham, London Croydon, Lewisham and Hackney districts.
Prior to London, the United States' Los Angeles, Las Vegas and New York City had carried out LED lighting replacement projects throughout the city. London Mayor Boris. Johnson said: As our road system is loaded with thousands of street lights, we have good reason to refer energy and resources to the standards of the 21st century. This is the largest investment in the modernization of major roads in the history of the British capital. It not only reduces carbon emissions and cost savings, but also provides better and safer road facilities for Londoners.

         At present, the heat metering market commonly used heat table is divided into mechanical heat meter(Mechanical Heat Metering) and ultrasonic heat meter.The mechanical heat meters is consist of temperature sensor, flow sensor and calculator. With the aid of the temperature sensor, The Mechanical Heat Meters measure the inlet water and return water temperature. Flow rate sensor measures the volume rate of the hot water in the tube trough the time difference. The figures recorded will be delivered to integral calculator which calculates the total heat and displays.

 

       The mechanical Heat Meters sensors measures the flow rate through the circles of the wheels. According to the specification, The DN can be â‰¤40mm and ≥50mm. According to the inner structure, the small size mechanical heat meters can be single jet and multi jet. At present, our mechanical heat meters belong to single jet mechanical heat meters and they have higher request from the water quality. According to the counter of the flow sensor, the mechanical heat meters can be dry and wet type. Our mechanical heat meters are the dry type.Except mechanical heat meters,the Plastic Heat Meter is also a good product.
