Every residential , commercial and industrial enterprise needs an important instrument to keep a tab on its energy resources and its consumptions. Gas flow meters are ideal to measure the volume of various types of natural gases that are used for heating and cooking purposes. Gas flow measurement is gaining prominence with the soaring of the oil prices and alternative forms of energy becoming attractive choices for people. There are different types of compressed gases types used in various industrial applications.
A gas flow meter is commonly used to measure the volumetric flow of gas and is of different types depending on various factors such as the flow of the gas, the type of the gas and the range of the measurement of the flow. The measurement of any gas is a complicated affair as it is governed by factors such as temperature and pressure. Moreover, any compressed gas is made up of various constituents that may affect the reading. The various types of flow meters being commonly used include rotary meters, diaphragm meters, orifice meters, turbine meters , ultrasonic flow meters, and coriolis meters.
These flow meters are based on futuristic technological applications and have various advantages for the industry. These gas meters are used in industries that involve harmful or corrosive gases and even traditional industries such as pharmaceutical and food industry. One of the advantages of these meters includes their lightweight and superior built that makes it handling easier. Most manufacturers have a detailed instruction manual with every gas flow meter along with a variety of flowconsumption accessories and these products are easily interface to the automation system of an industrial unit or a factory.

Nation's growing middle class shells out more for foreign agricultural products
China has long taken a cautious approach to controlling its staple grain import quota each year to ensure food security, but when it comes to other foodstuffs , overseas agricultural products are being warmly welcomed by the nation's fast growing middle class.
Thanks to the country's fatter wallets and increasingly diverse diet, China imported 320,000 metric tons of fresh milk and 283,000 tons of mutton in 2014, up 73.5 and 9.3 percent year-on-year, according to the General Administration of Customs.
The world's most populous nation also purchased 71.4 million tons of soybeans and 383 million liters of wine from overseas markets , up 12.7 and 1.6 percent, respectively, from a year earlier.
The value of its fruit imports reached $9.19 billion last year, rising 6.3 percent on a year-on-year basis.
Ding Lixin, a researcher at the Chinese Academy of Agricultural Sciences in Beijing, says even though the prices of mining resource-based commodities such as coal and iron ore are quite low at the moment in the global market , international wine producers, meat suppliers and dairy product providers have become the biggest beneficiaries of China's market boom for agricultural products.
"The stable growth of China's agricultural output and rising national incomes have provided diversified access to food with a higher protein content and better taste," says Ding.
"As a result, China has adequately raised the quantity of its grain imports, especially corn, soybeans , rapeseed meal and sorghum, over the past decade to support the growth of its livestock and aquatic feed industries."
Food consumption is normally a clear indicator of a nation's economic health and the size of its population. In China, meat consumption is rising, and people are eating a greater variety.
Staple foodstuffs such as meat, fish, eggs and milk have become more sophisticated , and consumers now look for more choices in terms of health and convenience.
As many people in China, in particular in urban areas, are increasingly aware that pork contains more fat and less protein than lamb, the country's pork consumption and import volume dropped 2 and 3.3 percent on a year-on-year basis in 2014.
Yu Bin, director of the department of macroeconomic research at the State Council Development Research Center, says although changes in food consumption reflect greater economic vitality , the country's ongoing urbanization and upwardly mobile population are other key factors that have shifted Chinese diets from being mostly grain-based to ones that include more meat and dairy products.
Chinese citizens consumed an average of 17.2 kilograms of mutton per capita in 2014, compared with 12 kilograms in 2008. The Beijing-based China Meat Association predicts that this figure will reach 28 kg between 2017 and 2022.
Yu says demand for lamb in China's western region, particularly in the Ningxia Hui and Xinjiang Uygur autonomous regions, and Qinghai and Gansu provinces, has quickly grown over the past five years, mainly because it is getting more expensive to raise sheep in western China , where the economy and livestock industry are less developed than in the eastern provinces.
Due to rising feed prices, limited grazing land and the breeding cycle, China's sheep breeding sector lags behind consumer demand, resulting in higher lamb prices over the past five years, according to a report released last December by the Chinese Academy of Agricultural Sciences.
"As China has found it impossible to grow all of the food it needs and has consequently formed closer ties with the world food market, demand for fruit , olive oil, wine, meat and dairy products will certainly . |
