公称口径40mm及以下的水表通常称为小口径水表,公称口径50mm及以上的水表称为大口径水表。这二种水表有时又称为民用水表和工业用水表,同时这种分法也可以从水表的表壳连接形式区别开来,公称40mm及以下的水表用螺纹连接,50mm及以上的水表用法兰连接。
Product overview
Water meters with a nominal diameter of 40 mm or less are usually referred to as small-diameter water meters, and water meters with a nominal diameter of 50 mm or more are called large-diameter water meters. These two types of water meters are sometimes referred to as household water meters and industrial water meters. In addition, these two kinds of water meters can also be distinguished from the case connection. Water meters with nominal diameter of 40mm and below are of threading type, and water meters with nominal diameter of 50 mm and above are of flanging type.

◎ No worm gear transmission mechanism. The impeller directly drives the counter, with high transmission efficiency and low start-up flow rate
◎ Wide metering range, suitable for occasions with large flow changes.
◎ Full flow rate metering, with high metering accuracy.
◎ Dry magnetic transmission structure to ensure clean counter and clear display.
◎ Six-digit large digital character wheel display reading. The reading is better for reading.
◎ Detachable metering core structure for easy maintenance.
◎ Internal adjustable structure to prevent private adjustment.
◎ Built-in stainless steel strainer to effectively protect the metering mechanism.
◎ High wear-resistant bearing system (jewel bearing for aviation instrument + high wear-resistant carbide shaft) to ensure long-term stability and reliability of the product and significantly increase the maximum flow rate of the product.
◎ Stainless steel fasteners and epoxy resin powder shells are sprayed inside and outside to maximize rust prevention and extend product life.
◎ Optional prying-resistant protective cover. (Prevent users from disassembling the core, destroying or changing the measuring mechanism to maximize
