Features: large flow capacity, small pressure loss, resistance to water impact and pollution; Removable structure for easy repair and maintenance; Indicating mechanism adopts magnetic transmission structure, the reading is clear and intuitive (the counter part also has liquid seal type for users to choose).
Conditions of use:
Water temperature: 0℃ ~ 40℃ (cold water meter) 0℃ ~ 90℃ (hot water meter)
Water pressure: ≤1MPa (1.6mpa when special requirements)
Maximum allowable error:
(a) From the low zone including minimum flow (Qmin) to the low zone excluding boundary flow (QT) : ±5%
(b) From high zone including boundary flow (QT) to high zone including overload flow (QS) : ±2% (hot water meter ±3%)
