1Product Overview
A compound water meter, commonly known as a mother child water meter, consists of large and small caliber water meters and flow conversion devices. The flow conversion device automatically controls the water flow to only flow through the small-diameter water meter or to flow through both the large-diameter and small-diameter water meters based on the magnitude of the flow through the water meter. This product has a wide measurement range, covering both large and small water meter flow rates, and is a product with a relatively large range for all types of water meters. Suitable for water metering in situations with significant changes in flow rate.
IIProduct Features
l The initial flow rate is small and the measurement range is wide, which can meet the measurement of both large and small flow rates.
l The product has a novel structure and is easy to install and maintain.
