We can do very little without electricity and gas. We need it on a regular basis to perform small task like cooking food or reading a book in the dark. One understands the importance of electricity when there is a power cut and you need to complete important tasks on your computer or during the summer when you absolutely need the fan.

Have you ever wondered where electricity comes from and how it reaches your home? Mostly electricity is generated by hydropower as it is a renewable source of energy. This basically means that through the gravitational force of water falling from a height, electric power can be generated. A dam is built to block the natural flow of the river, so that water is collected. Once adequate water is collected, it is released with pressure which forces the water to fall down shafts and directly into huge turbines. Due to the pressure, the turbines turn and thus electricity is produced.

Around 150 countries across the globe produce hydropower with China being the largest producer. As no fossil fuels are burnt in the production of hydropower, it is very useful in reducing carbon emissions. It is more eco friendly than burning fossil fuels or energy produced from coal and oil. The biggest advantage of using hydroelectricity is that it is relatively low in cost. There are also a few disadvantages of using hydroelectricity. The process of stopping the flow of water with dams causes damage to the ecosystem. By damming rivers, the flora and fauna are affected, silt gets accumulated and fishes die. There is also the ever present danger of the dam breaking, leading to flooding in the nearby area. People also have to be displaced where the hydroelectric project is constructed causing loss of homes and loss of livelihood for thousands of local people.

To determine where to set up a hydroelectric power generation project, a lot of factors need to be considered. One would have to calculate the water depth, seabed conditions, currents, flow assurance and much more. For this purpose subsea flow meters come in use. Subsea flow meters are most often used in oil and gas industry but they can also be used in hydropower projects. Flowmeters monitor all the critical processes and gives accurate measurement of the liquid or gas.

While choosing a flowmeter, one must select one which provides accurate readings every single time. You need to think about the fluid that needs to be measured and also the viscosity if the liquid that has to be measured is not water. A subsea flow meter usually consist of an OEM flowmeter body. There are many companies in the UK and provide good quality flow meters and turbines which can effectively be used in hydroelectric power generation.
