Noncon G4 series vortex flow meter

Low flow stability and 1:20 range ratio;

The multivariable vortex flowmeter with built-in temperature sensor can measure temperature and mass flow

G4 series vortex street flow sensors adopt a new type of digital signal processing circuit with simplified and high efficiency and low power consumption.Creative use of adjustable charge matching amplification, adjustable gain transformation and fine partition filtering front-end preprocessing hardware, according to the most modern FIR filtering, window function and FFT spectrum analysis and other wavelet signal theory for time and frequency domain software processing.According to the concept of zoning restrictions on the A/D conversion MSP - with the vortex signal of hybrid digital signal processing, the 16 segments range limit filtering, better solved due to the uncertainty of the flow medium density and viscosity of vortex street circuit operating frequency deviation considerably, the filter band do not tally with the field work that cause the problem of measuring large distortion.The original flow waveform analysis concept, which is based on waveform matching and signal-to-noise ratio to determine the lower limit of the measurement, has greatly improved the problems that have long plagued vortex flowmeter, such as poor seismic resistance, unstable lower limit and poor resistance to 50Hz electromagnetic interference.The working parameters can be set precisely.After mixed processing by hardware and software, the output frequency corresponding to the flow rate can accurately measure the flow rate of gas, liquid and steam in a wide range of flow rates.
