A diameter ruler, also known as a diameter tape or diameter measuring tape, is a specialized tool used to measure the diameter of cylindrical objects, such as pipes, rods, or tubes. It is designed with a flexible tape or ribbon that is marked with diameter measurements instead of linear measurements like a regular ruler.

This is an accessory for pipe grooving machine, after you have finished grooving of pipes, you can measure the pipe with this tape.

Here are some key features and usage guidelines for a diameter ruler:

1. Construction: A diameter ruler typically consists of a flexible tape or ribbon made of durable material, such as fiberglass or steel, with diameter markings printed or inscribed on it. The tape is often encased in a protective housing, and it may have a locking mechanism to hold the measurement in place.

2. Diameter measurements: The diameter ruler is marked with diameter measurements instead of linear measurements. The markings on the tape indicate the diameter directly, eliminating the need for additional calculations or conversions. The measurements are usually displayed in both inches (imperial) and millimeters (metric) for versatility.

3. Measuring process: To measure the diameter of an object using a diameter ruler, wrap the flexible tape around the object so that it fits snugly without overlapping or stretching the tape. Ensure that the tape is positioned perpendicular to the axis of the object. Read the measurement directly from the diameter markings on the tape where it overlaps or aligns with the starting point.

4. Accuracy and precision: The accuracy and precision of a diameter ruler depend on the quality of the tool and the clarity of the markings. Higher-quality diameter rulers will have clear and legible markings, and they may have additional features like a non-slip grip or a locking mechanism to enhance accuracy.

5. Application: Diameter rulers are commonly used in various industries and applications where measuring cylindrical objects is necessary. They are particularly useful in fields such as plumbing, construction, metalworking, engineering, and manufacturing. Diameter rulers can be used to measure the diameter of pipes, shafts, rods, and other cylindrical components.

6. Care and maintenance: To ensure accurate measurements and prolong the lifespan of a diameter ruler, handle it with care and avoid bending or kinking the tape. Keep the ruler clean and dry, and store it in a protective case or pouch when not in use. Regularly inspect the ruler for any signs of damage or wear that may affect its accuracy.

It's worth noting that digital calipers or micrometers can also be used to measure the diameter of cylindrical objects with high accuracy. However, diameter rulers offer a more portable and quick solution for rough measurements in the field.
