Abstract
A flow-rate meter has a cylindrical housing in which a counterweighted blade is pivotable on a shaft about the axis of the housing which is subdivided by a radial partition, an inlet port and an outlet port opening axially into this housing on opposite sides of the blade. The blade is magnetically coupled with a logarithmic scale and is provided with a logarithmic spring against which the force of the water flowing past the blade works.
