<p>The present idea refers to a method for calibrating a flow sensor and to a flow sensor arrangement. In the flow sensor arrangement, a main path (1) for a target fluid to flow through is bypassed and a flow sensor (3) is located in the bypass (2). By means of a removable plug (4), the main path (1) can be sealed during calibration. A target sensor output (t t0 (Q tot )) is determined respectively by supplying the bypass (2), and the bypass (2) in combination with the main path (1) with a reference fluid , and the bypass (2) with the target fluid. The respective sensor outputs are put into relation to each other and allow to determine for a target sensor output (t t0 (Q tot )) for the target fluid supplied to the bypass (2) and the main path (1) in combination. By way of such method and arrangement, there is no need to expose the main path (1) to the target fluid during calibration which might be beneficial in light of the target fluid possibly being of toxic nature, or being too expensive.</p> |
