How to solve the vortex street flowmeter has flow display but no fluid flow?

How to solve the vortex street flowmeter has flow display but no fluid flow? Vortex flowmeter is mainly used in industrial pipeline medium fluid flow measurement. Some friends may encounter when using some problems, such as the instrument shows no fluid flow, but the pipe then we analyses the problem for you. Vortex street flowmeter the cause of the problem: 1, the sensors in the detection sensitivity of the amplifier is not appropriate. Once at the end of the pipe blowing clean welding slag, iron and other sundry between the probe and the lining, that the probes are not vibration. 2, bad instrument grounding and due to external interference is introduced. 3, the sensitivity adjustable too low, can not transfer too low sensitivity, otherwise it will cause traffic on the high side or instructions, too low, no instructions, display instrument should be in commonly no flow and no interference, make the retail display instrument or mouth. No 4, the pipe flow or small flow, velocity is very small, resulting no vortex is formed within the sensor. Five, pipe has strong mechanical vibration, which leads to the display instrument and display, but there is no fluid flow pipeline. Above we analyzes the vortex street flowmeter for everybody instrument display but no flow pipe, the recommend of flowmeter correct grounding and adjust the sensor sensitivity. Superfamily shihua is specialized in all kinds of vortex flowmeter, ultrasonic flowmeter, electromagnetic flowmeter, flow meter, such as research and development, production and sales, welcome friends to come to the choose and buy products in need.
