How well do counters work?
Broadly there are two factors that ultimately determine the quality of the data collected by any counter installation. 3.1 Site design and infra-structure. These are critical to the performance of a counter. If the site is inappropriate to the equipment being used or if units are exposed to damage the performance of a counter will be drastically reduced. 3.2 Equipment reliability. Considering that counter installation are sited in relatively harsh environments subjected to winter floods, debris and general wear and tear, counters, if well maintained can perform exceptionally well.
