Abstract

PURPOSE:To omit an oscilloscope, miniaturize the entitled testing device and reduce the load of the operator by attaching an oscillation variation monitoring circuit to monitor the variation of oscillation of vortex signals. CONSTITUTION:An air filter 2 is attached to the upper stream of a vortex flow meter 1 to be tested which is arranged in the flow passage. Plural voice speed nozzles 4 with different flow rates are fitted to the standard flow rate part 3 which can obtain accurate and stated flow rate and these nozzles can be selected according to the requirement. A vacuum pump 5 is arranged on the lower stream side of the same flow passage as that of the air filter 2, the vortex flow meter 1 to be tested and the standard flow rate part 3 to make a flow material flow into the flow passage. When receiving a vortex signal, a testing part 8 measures and checks the flow rate. An oscillation variation monitoring part 9 monitors whether the oscillation of the vortex signal exceeds a required set point or not during the test time.
