Weigh in-motion vehicle scale suitable for use in a variety of applications. The Weigh  in-motion scale consists of two rugged steel paltforms each supported by four cpmpression strain gauge load cells. Each platfrom is designed to weigh one end of each vehicle axle.  The two platforms make up a weighing surface that is 12 feet (3.7 m) wide by 30 inches (0.76 m) long and can weigh vehicle travelling at a speeds up to 45 mph (72 km/h).

Weigh  in-motion scales are used in highway weigh stations and ports of entry to identiry heavily loaded vehicles and direct them to a static scales for enforcement weighing.  Data from in-motion scale may also used to determine vehicle classification or to be used in traffic flow studies.
