A domestic knowledge-based company has designed an anti-hail system that can turn hail into in to prevent damage to trees and facilities during hailstorms.
The system can liquefy the hail through a special process before they reach the ground.
“The anti-hail system turns the hail into raindrops by producing special sound waves in the sky,” Alireza Nourian, the CEO of Ervin Hail Industries Company, was quoted as saying by the news portal of the Vice-Presidency for Science and Technology.
He pointed out that the most important advantage of the domestic anti-hail system is the ability to prevent any potential damage during a hailstorm.
The system creates a series of acetylene gas explosions in a special reactor, which gives rise to sound waves with a special frequency. Then the device directs the sound waves into the thunderclouds. The waves disturb the formation of hails by creating turbulence in ice crystals, which turn hailstones into raindrops.
The anti-hail system can be used to protect crops, gardens, urban areas, industrial sites, car companies’ parking lots and any open warehouse where goods, products, or equipment need protection during a hailstorm.
The director of the knowledge-based company explained that the domestic anti-hail system is 30% more effective and cheaper than its foreign counterparts.
“The system has been designed in two forms. One is a semi-intelligent system that is designed for the first time in the Middle East and the second model is the first smart system designed in the world,” he said.
The domestic system has met the needs of the country for anti-hail systems and prevented currency outflow. So far, 500 anti-hail systems have been installed in the country.
Also, the domestic anti-hail system is exported to Turkey and foreign customers have confirmed the quality of this system.
Nourian noted that the design and development of the anti-hail system have led to the creation of numerous direct jobs and 20 indirect jobs.
Ultrasonic Water Meter Cost-Effective
A knowledge-based company has designed a smart water meter with very high accuracy and additional features to replace mechanical meters.
“The ultrasonic smart water meter has higher accuracy than traditional mechanical meters,” Abolfazl Janfada, CEO of knowledge-based Be Saaz-e-Energy Company, said.
In a housing unit under construction, a water meter is installed on the inlet pipe and another on the outlet pipe so that the difference between incoming and outgoing water helps calculate the amount of hot water consumed.
The meter helps measure the consumption of water and thermal energy in different parts of the building to calculate the water and gas bills of each housing unit, as well as those of industrial units.
It measures fluid velocity, instantaneous and volumetric flow, direction of water movement, meter operation time and water temperature.
The lifespan of this meter is 2-3 times that of mechanical meters and due to its very small measurement error, it helps customers pay the real water bill.
With this product, the water flow can be turned off for a consumer who exceeds the consumption pattern, or refuses to pay the water bill. It has been marketed at a lower price, which can compete with similar European models.
The software and hardware of this product have been designed by the company’s specialized workforce.
Flame Monitoring System Matches Foreign Models
Another domestic company has developed a flame monitoring system that helps monitor the flame in equipment such as power plant turbines, where the continuity of the flame is vital.
“Typically, a flame monitoring system consists of one or more sensors and a trigger. The function of the starter or amplifier is to receive a signal from the flame detector sensor and announce its status," Mehdi Arianfard, a member of the board of directors of Sang Chin Zahedan Company, said.
Gas turbine is one of the most important equipment in the oil, gas and energy industries. The important task of monitoring and evaluating its efficient performance is handled by the flame monitoring system.
The color of the flame varies from infrared to ultraviolet, depending on the type of fuel used. As the fuel used by turbines is natural gas, its flame has more ultraviolet components.
With the production of this strategic and practical system, there is no need for foreign counterparts.
“South Pars Gas Company has replaced a foreign system with a domestic one for monitoring gas turbines,” he added.
In addition to turbines, the flame monitoring system is also used in furnaces.
“Currently, we can meet the country’s demand without the need for imports. The domestic system has prevented a large amount of capital outflow,” Arianfard said.
“While matching the quality of foreign models, it has been marketed at a lower price. It costs more than $2 million a year to import foreign counterparts.”
