In-Motion Weighing Indicator - MSWIM | Arete | Excellence in Dynamic Weighing

Ar-i8000+ (MSWIM) Indicator is a state of the art, scalable, intelligent, accurate and high-speed real-time system that interfaces to load-cells banks to extract axle weight, speed & spacing information of axles passing over the weigh-bridge.
Ar-i8000+ used by our OEM customers is approved for MSWIM applications (up to 60 KMPH) by Govt. Of India.
Indicator capable of interfacing with load-cell based sensors as well as bending plate sensors.
The indicator is designed to seamlessly plug-in to the next higher level application software (Toll Management software)
Additional customization to cater to a specific need is possible due to its scalable and reconfigurable hardware and software architecture.
Designed in India
