Abstract
A multi range flowmeter, connected inline a fluid supply line for flow measurement, comprises at least one low range flow sensor for measuring a branch-flow of fluid passing in a branch that branches off a trunk; a flow driven valve configured to pass fluid from the trunk when a trunk-flow in the trunk exceeds a preset flow level; and a high range flow sensor for measuring the branch-flow and the trunk-flow, wherein the flow measurement is the measurement of the branch-flow when the trunk-flow is below the preset flow level, and wherein the flow measurement is the measurement of the branch-flow and the trunk-flow when the trunk-flow is above the preset flow level.

A multi range flowmeter, connected inline a fluid supply line for flow measurement, the multi range flowmeter comprising:
- at least one low range flow sensor for measuring a branch-flow of fluid passing in a branch that branches off a trunk;
- a flow driven valve configured to pass fluid from the trunk when a trunk-flow in the trunk exceeds a preset flow level;
- and
- a high range flow sensor for measuring the branch-flow and the trunk-flow, wherein the flow measurement is the measurement of the branch-flow when the trunk-flow is below said preset flow level, and wherein the flow measurement is the measurement of the branch-flow and the trunk-flow when the trunk-flow is above said preset flow level.
