Beta Axle Volume Counter - Refurbished

These are simple two-tube interval volume counters. The interval length is pre-programmed by connecting the counter to VIAS. Because it only saves the number of strikes on each sensor per interval, the data files are very small. But that also mean this counter can only record axle volumes. A Beta cannot be used for classification, speed, gap or per vehicle studies. It is also limited to road tube layouts 11, 21, and 31.
