GB-1.6 Class B Micro ultrasonic gas meter
Genaral description
GB 1.6 type micro ultrasonic gas meter case 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.
