This invention discloses apparatus and method for checking the calibration of a fluid turbine meter without interrupting the line service. A flow directions sensing means is inserted at the downstream side of the flowmeter so that the angle of flow of the discharge from the meter may be checked from time to time without removing the meter from its flow line. Any change in this angle indicates a possible change in response of the meter.
