Product Description

No Moving Parts, high accuracy for years long. No moving components in the flow sensor, avoid long-term abrasion of mechanical parts which may result in inaccurate measurement and failure of the meter. Such design is also resistant to impurities, therefore no inspections and maintenance are cost-free.
