The present invention relates to a flow indicator or flowmeter with an impeller which is rotatably mounted in an essentially circular-cylindrical flow chamber of a flow housing which has an inlet channel and an outlet channel. To be able to use such an indicator and measuring device to achieve a high accuracy of measurement for a wide measuring range without any calibration, the present invention provides that a nozzle plate (14), having a nozzle hole (15) of a pre-determined cross-section, can be inserted so as to be exchangeable, e.g. can be screwed, into the inlet channel (1) and/or the outlet channel (2), and that the diameter D (in mm) of the nozzle hole (15) can be fixed as a function of the lower limit R1 (in litres of water/min) of the measuring range such that the diameter D increases with the increase in the value of the ratio V = R1/D, whereby V has a value of about 0.075 litres of water/mm.min if the diameter D amounts to about 1.25 mm and a value of about 0.3 litres of water/mm.min if the diameter amounts to about 20 mm.
