Product Introduction
The water flow bubble detector MWFD (Minyuan Water Flow Detector) uses a high-frequency capacitance detection chip to measure changes in the dielectric constant of the liquid inside the tube: different capacitance values reflect whether the tube contains air or liquid. When air is detected, it outputs a high level for alarm. The sensor has strong penetration, effectively overcoming issues such as different pipe materials, thick pipe walls, and differences in liquid conductivity. The sensor has fast response, with a detection cycle up to 10ms, and combined with a microprocessor algorithm, it can distinguish the current state within 300ms. The built-in microprocessor chip allows for parameter calibration, temperature compensation, detection algorithms,and alarm threshold configuration.
Non-contact capacitance detection method, high-frequency excitation with strong penetration.
