Accreditation-ready Water quality Remote meter System is an economical solution for the accredited operation of several water quality meter stations in a larger region. The meter stations use Internet connection to transfer the data to the system center, and they can also be remote-controlled from the system center. In addition to the measured data, the meter stations also transfer all the parameters of the measuring unit, which represent the appropriate operation of the functional units of the station as well as the meter-technological characteristics of the measuring equipment. The applied analyzers generate status signs based on which the cause of the potential error can be identified. The analyzers are able to measure control solutions via remote control. The software of the system center ensures the generation of status reports belonging to the desired times and parameters, based on which the accreditation-compliant operational status can be verified.
