Measuring Wheel Surveying Accessories in Pakistan are excellent
tools for measuring long distances in a hurry. Some people call
distance measuring wheels "footage wheels" or "distance
calculation wheels". They are great for estimating paving jobs,
building lot sizes, carpet estimates, grass seed and fertilizer
calculations, insurance calculations, fence estimating, utility
contracting, and other uses when a large distance measurement is
needed quickly. To use, simply reset the counter, place the
wheel at the point you want to start measuring, and roll in a
straight direction to the stopping point, then read the counter.
Hence, the reason they are called a "Rolling Tape Measure".
There are a few things you need to be thinking of if you're going to get the best measuring wheel for you that fits your needs. First, there are different sizes of Distance Measuring Wheels that you can choose from such as; a small wheel for indoor measuring, a medium wheel for both indoor and outdoor, or a large wheel for outdoor only. Generally speaking, the rougher the terrain, the larger the wheel, and the smoother the terrain, the smaller the wheel. Also, theres a choice of counters and units and there are basically two types of counters to choose from; Mechanical or Electronic. The Mechanical counters offer only a single unit of measure (your choice), and the Electronic counters offer multiple units of measure all in the same model of measuring wheel. Mechanical counters are great if you don't want to rely on batteries and you usually work in one type of units. Electronic counters are great if you want to have multiple types of unit measurements (inches, feet, metric, yards, etc) all in a single model of measuring wheel.
