Product Description

With an aim to be a market leader in our domain, we have been engaged in the business of manufacturing and supplying Slow Speed WIM. It is installed at toll plaza, entry points, or borders to check the weight of vehicles. Abbreviated for weight in motion, this WIM is made having a sturdy steel plate with load cells. It serves as a standalone system for verification of overload conditions. Slow Speed WIM is mounted at the ground level with the help of fasteners.



  • Accurately weigh at the vehicle speed of 0 to 20 kilometers per hour

  • Ability to withstand adverse climatic conditions

  • Low maintenance



Slow Speed WIM


The MVR Weight Indicator for In-Motion Vehicle Scale offers the ideal combination of accuracy and speed.

  • GLCD display with four keys on the front panel of eldon MS box.
  • Serial strings for communication as per your requirement.
  • Logic with two loops and one IRS (pnp) type.
  • MVR will supply two parallel sensing Light curtains with each controller.
  • The Light curtains will installed in a box near WIM along with junction box by MVR
  • A power supply of 24V to drive IRS.
  • LEDs on mother board for loop sensors and IRS.
  • This is low speed (max speed 20 kmph) system with accuracy of 2-4% of fsc and depends on the level of section before and after weighing zone.

Key Benefits

  • High vehicle throughput
  • Maximize operational Productivity and cost savings
  • Gross weight, axle weights, numbers of axles can be recorded along with average speed
  • Suitable for overload detection, statistic data collection, road maintenance planning etc.

Surge Protector / Junction Box

MVR Technology has introduced a Lightning protection Junction box for Analog & Digital load cell with better protection against lightning and high voltage Surge. Special components to enhance protection against Lightning Strikes have been incorporated. This will enhance performance, reduce down time and reduce field calls for WIM installations using DESB Load cells..
