Symptom one common faults caused by the vortex flowmeter amplifier and exclusion method: no instantaneous flow rate indicator. Possible causes: low-gain amplifier or amplifier damage. Remedy: W1 is rotated clockwise to increase the gain, amplifier repair or remove such bad repair, replace the amplifier. Symptom bis; no flow within the pipe flange vortex flowmeter model, but there are flow display indicator. Possible causes: Amplifiers adjustment of status and conditions of use does not match Remedy: counterclockwise rotation W1 three fault phenomena: steady flow within the pipe, but flow display unstable. Possible causes: Amplifiers adjusted. Remedy: Adjust W1 Symptom IV: The flow increases, but smaller display. Possible cause: the filter parameters of the amplifier is incorrect. Remedy: Check the parameters. Vortex Flowmeter advantage compared with the throttle pressure flowmeter, vortex flowmeter has the following advantages. ① simple structure, strong, easy installation and maintenance. Impulse control and without the three valves and other Flanged vortex flowmeter, reduce leakage, clogging and freezing. ② higher accuracy Flanged vortex flowmeter retail, usually (1 ~ 1.5)% R. ③ measuring range, reasonably determine the flowmeter vortex diameter flange range of up to 20: 1. ④ pressure loss is small, about throttle pressure meter 1/4 to 1/2. ⑤ output pulse signal proportional to flow, no zero drift. ⑥ within a certain Reynolds number range, the output frequency is independent on the composition and fluid properties (density, viscosity), the meter factor only vortex shape body and piping occurs size.
