Thus multiplying the final reading of the planimeter in m2 by 2 will give you the reading in square feet. Planimeter. By Using Measuring Wheel. A measuring wheel is another method of measuring the area. In principle it is like a planimeter that you have to go over the perimeter of the area with it, only you have to do it on the actual land. Abstract In this experiment, a Planimeter was to measure the areas and lengths of 4 different sketches. The first sketch was a simple triangular area; the second was a combination of straight lines and arcs. The third is a combination of straight lines, arcs and irregular lines.   This measurement app is useful for outdoor activities and can be used by amateurs and professionals in various industries like sports, farming, landscaping, construction, repairing, fencing.   CIVIL_ENGINEERING A planimeter will give correct results for "any" scale factor whatsoever, at least within the tolerance imposed by the operator and a small mechanical uncertainty. In practice, an operator will trace an area on a plan with a known scale factor, and then multiply the "raw" planimeter reading by a constant, Ca, to.

When it comes to measure the area of the 2-dimensional figure, there are several options available in the market. One such instrument is the digital planimeter. This instrument is used to measure the area on the maps of any scale. This most prominent feature of this instrument is that it is very effective in measuring the area of the irregular.   The mechanical planimeter has a vernier or tick marks on a meter that you reference and then multiply the data against a multiplier (using your hand calculator) to get area. An electronic, or digital, planimeter you enter the scale of your drawing into the planimeters keyboard and it . Area = M (B – A + 10N + C) Where, A = initial reading. B = final reading. N = no. of completed revolutions of wheel during one complete tracing. N is positive if dial passes index in clockwise, N is negative if dial rotates in anti-clock wise direction. M and C = constants which values are provided on the : Sadanandam Anupoju. DESCRIPTIONPlanimeter is a powerful tool to measure and calculate distance between multiple points on the map, and land area, all expressed in the measuring units you egory: Calendar & Time Management Software.

  A. Planimeter can be used in industries in measuring for road repairing, concrete, seal coating, roofing, paving, fence, underground utilities. Also useful for map measure, outdoor activities, sports, range finder applications, bike run tour planning, explore golf area, golf distance measure.   PLANIMETER - tool for area, distance, angle, bearing, measurements on Google Maps, GPS tracking, data sharing and track planning. Planimeter has a . AREA BY PLANIMETER.— A planimeter is a mechanical device that you can use to compute the area of an irregular figure after tracing the perimeter of a scale drawing of the figure with the tracing point on the planimeter. The most commonly used instrument is called the polar planimeter. Figure shows a polar planimeter. Area Planimeters. Planimeters. Planimeters. The planimeter is a drafting instrument used to measure the area of a graphically represented planar region. The region being measured may have any irregular shape. Sort Order.
