Flowmeter for liquid or gas particularly for measuring heat usage where heat is delivered from a shared or zero energy plant has a design that is cost-effective and remains accurate over long time periods

摘要

Flowmeter comprises a freely moving, practically floating body in the form of a hollow sphere of suitable density material, that is arranged in a flow channel arrangement that causes it to rotate. This causes it to generate impulses that are detected by a suitable display or reporting device. Alternately transparent material can be used for the housing and parts and the rotation can be directly optically observed.
