The construction of an inclined surface or a crown depends heavily on the measurement of the angle of slope in terms of continuous accuracy. Slope meters measure the tilt angle using a tilt meter, tilt indicator, level gauge, level meter, or gradient meter. It can measure both the inclines or positive slopes, as well as the declines or negative slopes.

The meter basically has two component parts. First is its base or flat side which is mounted on a surface, and the second is a half-filled hollow disk which stands on the base. Liquid fills almost half the volume of the disc and shows the desired inclination or tilt angle in respect to the base. A graduated scale of angles is marked on the glass surface of the disc, which gives the value of the tilt in degrees, percent, or topo.

The most crucial tool for all types of slopes and crown construction is definitely the inclination meters. It helps drive the bull-dozers, motor graders, and other similar equipment. "Percent of grade" can also be determined while working on asphalt pavers, tunneling machines, wheel ditchers, etc.

The instrument helps maintain the correct speed and optimum fuel consumption while driving up hilly roads. It is generally mounted on the dashboard in the driver's view. Correct and continuous measurement of the slope angle can fix the safe "curve-speed" with accuracy.

When the meter is correctly installed on a motor grader or any other machine, the operator gets continuous and accurate indications of slopes. It enables them to construct designed slopes without any waves. The chance of cutting more slope, and thereby removing more dirt than what the operator is paid for, is also minimized when the instrument is in place.

During construction of slopes or grading, measurement of the inclination is of utmost importance, as it determines the estimation of the optimum cutting angle. In case excess cutting is done, extra rubble will be created, which need be removed for vehicles or machines that run for longer periods. Removal of the debris effects the efficiency both in terms of fuel consumption and time spent. Accurate slope values, therefore, are needed to decrease debris generation on these roads.

Water puddles on roads after a heavy downpour causes trouble for travelers and damages the road. This happens when some low spots or flat surfaces are developed while constructing the road. This problem can, however, be solved if the meters are used during road construction.

The continuous display of slope values doesn't allow any flat or low spot build up on the road if installed correctly on the machines used. The operator repeatedly checks the accurate value of the inclination, and takes corrective measures while casting slabs or laying asphalts on the roads. While constructing the intended slope, they also need to cut the surface and remove dirt and debris. There will be less rubble on the road if the meter is accurate.

The sensitive electronic tilt meters can give an output value of up to 0.0001 degree. Accuracy of a tilt meter depends on the range of data measured, initial setting of zero value, and sensitivity of the instrument. However, instruments need to be upgraded in case perfect accuracy is required in extreme temperatures with sub-zero values or intense heat.
