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 Jan Fada, 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 is measured to calculate the amount of hot water consumed, the news portal of Vice-Presidency for Science and Technology reported.
Using this product, it is possible to 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 in the industrial sector.
The meter 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 the customer pay the real water bill.
With this product, the water flow can be turned off for a consumer who exceed the consumption pattern, or refuses to pay the water bill.
This meter is 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 workforce and direct employment has been created for 20 people.
Multifunction Transducer
A knowledge-based company has designed and manufactured a multifunction transducer that can be used to monitor the power grid in small and large industrial complexes.
“In digital devices, especially digital measuring devices, one of the most important concerns is how to deal with an analog quantity,” Mohammad Reza Hashemi, CEO of Farayand Niroopardaz Company, said.
Hashemi pointed out that the multifunction transducer is based on the latest electronic technology, the Vice-Presidency of Science and Technology reported.
The main function of transducers is to convert one type of energy into another. There is no limit to the type of energy, as they convert each of the electrical, chemical, mechanical and thermal forms of energy.
Transducers are one of the main equipment in industrial electrical automation systems that can be used to monitor power grid parameters and convert them into standard signals.
Electrical parameters of this transducer are calculated after the conversion to a digital signal. These quantities are stored instantly in the system’s memory and can be recalled or applied to current or voltage analog outputs after digital selection by all isolated analog-to-analog converters.
Online network monitoring features, measurement of more than 120 electrical parameters of the power grid, remote measurement capability, 2 kV isolation between all parts and four isolated analog current and voltage outputs are among the special features of this domestic transducer.
It offers protection against short-circuit, measures total voltage, one- or two-way frequency, tolerates transient inputs up to several times the nominal values, has an internal clock equipped with a backup battery and a solar calendar with detectability, synchronization with location systems and occupies a small space.
“Knowledge-based companies need to enjoy benefits such as tax breaks to boost domestic production,” Hashemi said, while noting that about 15 jobs have been created in the production process.
“The foreign counterpart of the multifunction transducer is priced 12-fold higher and not economical for domestic companies. For this reason and in order to prevent unnecessary imports, knowledge-based companies should be supported,” he added.
Thermal Fogging Machine
A knowledge-based company has designed and produced a spraying device mainly used in the agricultural sector, which can also be used for the environmental disinfection by using the fogging method for the first time in Iran.
The decision to deal with the Covid-19 pandemic required the import of a large number of thermal fogging machines, which were largely prevented by the production of domestic models.
Following further research, the main use of this product was expanded to serve agricultural disinfection.
“The thermal fogging machine disperses the spray material in the form of a fog with dimensions of approximately 5-50 microns,” Abazar Vahdat, the CEO of knowledge-based Sepid Pajuhan Pars Company, was also quoted as saying.
The machine is designed in two models that have performed successfully. It could also be attached to the back of a van or car.
