volumetric rotary piston water meter

Feature: -- Adopt volumetric rotary piston principle of measurement with conformity to ISO 4064 class C, High sensitivity enables the accurate measurement even at a low flow rate of 4 1/h, No location limitation for installation.Accuracy is not to be affected wherever installed at a horizontal,vertical or inclined pipeline Register is sealed with a special liquid to keep a clear reading in long term service Mechanical parts use of high-quality material to ensure a stable characteristic Working condition: 1 Water temperature ≤+50°C Water pressure ≤1MPa Maximum permissible error: (1) in the lower zone from qmin inclusive up to but excluding qt is ±5%. (2) in the upper zone from qt inclusive up to and including qs is ±2%; MAIN TECHNICAL SPECIFICATIONSTypeSize (mm)ClassqsOverload FlowqpPermanent FlowqtTransitional FlowqminMinimumFlowMinimumReadingMaximumReadingm3/hL/hm3LXH-1515c31.522.5150.00019,9992 DIMENSION CodeDescriptionQTY1Nut22Coupling23Gasket24Copper Wire15Seal lead16Bottom Body17O-ring18Non-return Valve19AStrainer19BChamber19CBush19DDivision plate19EPiston19FCover110Clamp frame111Spring112Clamp slider113Transmission assembly114Register115O-ring116Upper body117Lid118Hinge pin1
