The replacement of analog meters with smart is costly, laborious, and far from complete in developing countries. Energy Company Parana (Copel) (Brazil) performs more than 4 million meter readings (almost entirely non-smart devices) per month, we estimate that 850 thousand them are dial meters. Therefore, an image-based automatic reading system can reduce human errors, create a proof reading, en...

With the development of the society, the demand of electric power becomes bigger and bigger. The phenomenon of unbalanced electricity in different time is worse and worse. In order to adjust electric power burthen with reason and save energy, we put forward the design of a novel multi-rate three-phase watt-hour meter. The design principle of a newfashioned multi-rate three-phase watt-hour meter...

Glucose meters are widely used today both in the inpatient and outpatient settings, and by the patient himself at home to monitor therapy. The glucose meters use whole blood. For good performance both technical accuracy and clinical accuracy is very important. Technical accuracy tells us about the closeness of agreement between a measured value and true value of a parameter whereas clinical acc...

The use of wireless automation in almost all the fields of power, gas and water generation, distribution and billing has come of age. Here with the inclusion of wireless communication with the automation may lead to paradigm change in the current trend. The design presents a new methodology for avoiding the high construction and maintenance costs in the existing meter reading technology. Apart ...
