Weigh-In-Motion (WIM) System

Weigh-In-Motion (WIM) System by Punit Instrument Pvt. Ltd. is an advanced weighing solution that measures vehicle weight while the vehicle is moving, without stopping or slowing down. The system captures axle load, gross vehicle weight, speed, and classification data in real time, enabling high-speed traffic monitoring and overload control.

WIM systems are widely used for highways, toll plazas, mining roads, ports, logistics corridors, and government enforcement applications.
