QK2000 Ⅱ Domestic Diaphragm Gas Meter is a lightweight gas meter. The volume is 0.8L, which is smaller and lighter than the conventional 1.2L diaphragm gas meter. The center distance of the 110mm joint can be eccentric through the elbow joint to adapt to the installation requirements of 90mm or 130mm pipe pitch. Similarly, the linear reciprocating spool valve structure is designed and equipped with an error adjustment system, so that it has high measurement accuracy, stable performance and good expandability.
