The technique of ultrasonic detector is steady and its anti-jamming capability is strong. 2. UD's accuracy rate is higher than loop sensor which has problem of weak magnetic and repeated detection. The base plate of UD is zoom type to avoid the problem causing by different setting angles without error accumulation. 3. UD has two detection methods, one is to detect the ground, the other is to detect the vehicles. Both of them are available for all kinds of car park's terrain. 4.
