skivflödesmätare

A skivflödesmätare, also known as a disc flow meter or disc meter, is a type of water meter used to measure the volume of water passing through a pipe. It is commonly found in domestic water supply systems. The device works on the principle of a rotating disc that is directly proportional to the flow rate of the water.

The core component of a skivflödesmätare is a tapered disc, often referred to as a "nutating disc" or "wobble disc," located within a chamber. As water flows through the chamber, it causes the disc to oscillate or wobble. This oscillating motion is transferred to a mechanical counter mechanism, typically through a shaft and gears. The counter then registers the total volume of water that has passed through the meter.

Skivflödesmätare are known for their relatively simple construction and cost-effectiveness, making them a popular choice for residential applications. They generally offer good accuracy for typical household water usage patterns. However, their accuracy can be affected by significant changes in flow rate, such as very low or very high flows, and by the presence of debris in the water. Regular maintenance and cleaning can help ensure continued accurate performance.
