A mass calculation and indicating device particularly for weighing moving vehicles (trucks) on the highway. It includes means for sensing both the impact of the mass of the truck, and the speed, each producing an electronic signal, and using the signals to indicate the total weight of the truck. The mass is sensed by an impact component having a bladder, operating on fluid displacement, and producing an electronic signal thereby. The speed is sensed by a radar component, utilizing the Doppler effect, and produces another electronic signal. The two signals determine a signal which indicates the weight of the truck axles. The axles are sensed individually, both as to impact and speed, and the signals produced by these two factors are used as to each axle to show the weight of each axle, and are themselves combined to show the final total weight of the truck. A component is included to sense the presence of the truck in the sensing range, and its departure therefrom, to detect individual trucks following one another and thereby control the signals relating to each individual truck.
