Different from Ultrasonic Heat Counters,The Smart Heat Meters are used
for heat and cold energy calculation through the water. The smart Heat Meters
can display the accumulated heat, flow rate, instant flow rate, inlet water temperature,
outlet water temperature, temperature difference and etc.
The smart heat meter
is suitable for measuring the heat exchange, known as the heat transfer fluid
or liquid absorbing thermal energy conversion equipment, which consists of a
flow sensor, temperature sensor and heat calculator(Heat Meter Counters) three parts. The smart heat
meters are also known as smart energy meters.
The smart heat meter is
used to measure and display the water flow through the heat exchange system
release or absorb heat. The smart heat meters are installed at the inlet pipe
or outlet pipe to measure accurate metering and intelligent control of charges
of the heat consumption. Its working principle is to install the smart heat meters
in the heat exchange system, when water flows through the system, according to
the supply and return water flow temperature, from the data from the flow
sensors and temperature sensor as well as the water flow time, the smart heat meter
will calculate the released and absorbed energy through the calculator.

A few days ago, there were 44 small rivers in Hainan, and 119 small reservoirs and small ponds were dry. The drought-affected area of ​​crops reached 267,600 mu, and more than 130,000 people had difficulty in drinking water temporarily. Nowadays, the drought is still continuing, causing huge losses to agricultural production, rice into empty shells, sugarcane growth stagnation, rubber stop cutting, papaya products, etc., and this number is still rising as the drought continues... planting The family is looking at the crops and dying, crying and crying...
Israeli drip irrigation equipment brings good news to growers
[China Agricultural Machinery Industry News] China's population, arable land, climate, water resources and other natural conditions determine that China's agriculture must follow the development path of irrigated agriculture. The status of irrigation in China's agricultural production is very important, the annual production of irrigated food It accounts for 3/4 of the national total and produces more than 90% of the economic crops.
Since May this year, there have been continuous high-temperature weather in Hainan Province, and no effective rainfall has occurred in the central, southern and southwestern regions, and 13 cities and counties have experienced different degrees of drought. Among them, Changjiang and Sanya reached a special level of meteorological drought. It is understood that the drought is a drought orange warning signal issued by Hainan Province in recent years.
Israel drip irrigation set as a grower to bring the gospel
However, not all growers are such focal scenes, such as Dingan planting grapes, bougainvillea, plumeria base, cantaloupe base planted in Ledong Jianfeng Town, Haikou, Qionghai Zhongyuan Town planting vegetable and melon base, Sanya planting seedlings, Orchid base, Wenchang, Chengmai Dala, Fukuyama seedling base and so on. The crops of these growers are almost unaffected, and they irrigate the crops every day, as always...
On the same piece of land, why is there such a big contrast? After many inquiries and investigations, the secrets were discovered: one of the common features of these growers was the installation of Israeli drip irrigation equipment! After the family visited, there was only one feeling of regret: Why not use drip irrigation technology earlier?
Using Israel's drip irrigation technology is equivalent to giving the growers a real “safe lockâ€!
Water-saving irrigation technology helps to alleviate the contradiction between water supply and demand
Agriculture is a major water user and an industry with potential for water conservation. Vigorously developing water-saving irrigation will naturally become an inevitable choice for China to alleviate the contradiction between water supply and demand.
The effectiveness of implementing water-saving irrigation is summarized as follows: one is to save water resources; the other is to increase grain output; the third is to improve the efficiency of fertilizers and pesticides; the fourth is to exert comprehensive benefits and promote the development of modern agriculture; Driven the development of water-saving industry.
The secret of Israel's miracle in the desert is the invention of drip irrigation technology, which will make use of valuable water resources. Drip irrigation uses a small plastic tube to deliver irrigation water directly to the root of each crop, forming an onion-shaped aquifer in the soil beneath the root of the crop, and the crop roots develop only in this onion-shaped aquifer. Water is slowly dripping from the dripper. It is a precise irrigation method. Only water where it is needed can be filled. It can really only fill the crop without filling the soil, and it can make the water in the root zone of the crop in a good state for a long time. . Compared with traditional water and fertilizer application methods, drip irrigation technology increases water use efficiency by 40% to 60%, and fertilizer utilization rate by 30% to 50%. Drip irrigation has not only changed Israeli agriculture, but has also changed the way agriculture is irrigated around the world. After the invention of drip irrigation, Israel's total agricultural water use has been stable at 1.3 billion cubic meters for 30 years, while agricultural output has increased by five. The application of large-area drip irrigation technology is Israel's "number one hero" to achieve water.
The benefits of drip irrigation are amazing
It saves precious water resources. In the traditional way of pouring large fields, 85% of the water is evaporated and not absorbed by the crops. The utilization rate is only 15%, and the surface drip irrigation can greatly increase the water utilization rate to about 80%. Subsurface drip irrigation can be increased to more than 95%, which is basically no waste.
The second is the invisible labor cost savings. After the pipeline is laid, the irrigation of a large number of farmland in the future will be controlled by a few farmers through smart equipment. With a mobile phone, you can water his crops at any time and anywhere, and the peasant’s sorrowful and painstaking waters are gone.
Israel drip irrigation is the world's drip irrigation technology, is the industry leader, masters the world's leading irrigation equipment technology, can provide advanced and high standards of drip irrigation, valves, controllers and water and fertilizer integration products, as well as greenhouse solutions.
