The safe driving speed for any curve is quickly and accurately determined with the Safe Curve Speed Indicator mounted in the engineer’s car.  The scale reads zero when the car is level, and will show “tilt” up to 25 degrees on each side.  The scale is red beyond +/-10 degrees to denote danger zones.  The “SCSI” was designed by Slope-Meter in accordance with the specifications of the Minnesota Highway Dept.  Traffic Division and is used nation-wide by highway and traffic engineers.

When Slope-Meter is correctly installed on a motor grader or other machines, it will accurately and continuously indicate the slope of the ground being graded. This accurate indication of slopes between surveyor’s stakes is very helpful, as it enables operators to construct true slopes without waves. With a Slope-Meter on each of your machines, you can be sure you will not move more yards of dirt than you will be paid for. Night work can be done just as accurately as in daylight. All your work is speeded up when Slope-Meters are on the job. Rain, dust, snow or sleet do not affect the accuracy of the hermetically sealed Slope-Meter.
