Application
GB 1.6 type micro ultrasonic digital natural gas flow meter using aluminum alloy die casting, the plastic made of high strength plastic molding and processing. This high quality materials and rational structure design to ensure that the product in the long-term work conditions, still can reach the target. Advanced micro ultrasonic principles through the change of piezoelectric sensor airflow, with high quality microprocessor calculation, therefore, is the ideal gas industry measuring instruments.GB 1.6 type micro ultrasound gas meter is suitable for natural gas, liquefied petroleum gas (LPG) and clean gas measurement.
Structure
The ultrasonic digital natural gas flow meter is in order to meet the market demand introduction of acoustic technology products, principle for air through aluminum alloy recessed, produce the vortex flow, its through the film piezoelectric patches, the vibration of the voltage signal, the voltage signal amplified, plastic and flow generation after proportional to the pulse signal. The monolithic integrated circuit to the pulse signal measurement and analysis, the conversion of the volume of a gas, single-chip microcomputer and the display and storage.
