[ Instrument R & D of Instrument Network ] The European Metrology Innovation and Research Program (EMPIR) launched the "Electrostatic Electromagnetic Interference" project, dedicated to developing methods to test the accuracy of electricity consumption of smart meters, used to solve fast transient current-related electrical interference The meter has a wrong problem.

Through high-precision measurement of actual electrical interference, the project team built a new test bench to evaluate the performance of the meter under similar conditions. In order to resolve billing disputes, we will determine how to design anti-interference meters based on on-site inspections, and develop new diagnostic algorithms to identify transient current types. The researchers hope that the results of the project will eventually support European and international standards and ensure consumer confidence in the use of smart meters.

Another EMPIR project under development is quantitative magnetic resonance imaging (MRI) analysis to help achieve more objective disease diagnosis.
MRI is a commonly used medical scanning technique. In Europe, more than 30 million MRI scans are performed each year. Standard MRI results are mostly qualitative, limiting their objectivity and comparability.
Therefore, EMPIR launched the "Physical Biomarker Based Quantitative Magnetic Resonance Imaging" project to evaluate new and assisted electrical characteristics tomography and magnetic resonance fingerprint printing technologies, and develop quantitative MRI analysis to achieve more objective disease diagnosis. These algorithms will first be tested with phantoms that mimic the characteristics of human tissue, and then applied to real clinical data.
Electrowinning Gold
The equipment is new complete equipment used in gold trade to recover gold from the gold-carrying carbon. It is suitable for desorption and electrolysis of gold-carrying carbon with different grades. The desorption is an intermixture of 1~2% sodium cyanide and 1~4% sodium hydroxide. The desorption solution is pumped to the heater by circulating pump and heated to the desired temperature. Then the solution flows downward to the bottom of desorption column, through the gold-carrying carbon in the column and upward to the top of it. During flowing, the solution strip gold from the carbon (at this stage the solution containing gold is called as pregnant solution). The pregnant solution runs out from the top of the column and into the electrolytic cell. In cell, the gold in the solution is electrically deposited in the steel wool of the cathode frame, and the rest (called as lean solution) flows back to desorption solution cell and recycled.
The gold mud containing rich gold and silver is taken out of desorption cell and transported to the separation section.
