Соединение счетчик воды

Compound water meter is also known as composite water meter consisting of detachable helix type water meter , small caliber helix type water meter and flow-rate interpreter installation automatically control whether the water flows through the small caliber water meter or through both meters according to the floe rate through the water meter. Thus the measuring range is between the minimum flaw-rate of the small cailber water meter and the maximum water rate of the big cailber water meter. Features: •easy to maintain •small starting flow-rate •wide measuring range • lowhead loss •Reed switch option •Particularly suited in commercial •institutional places of assembly and facilities with fluctuating usage and flow rates •The main register may rotate more than 360° for easily reading in any position Main technical data: ModelDNQsQpQtQminMinMaxmmm3/hm3LXF-808080400.20.050.0001999999+99999LXF-100100120600.20.050.0001999999+99999LXF-1501503001500.80.20.0019999999+999999 Dimensions and weight: ModelDNLengthHeight(H)Height(G)Width(B)Connecting FlangeWeightmmOuter Dia(mm)Bolt circle(mm)Connecting bolt PCSKGLXF-8080370276400310Ø200Ø1608 x M1627.5LXF-100100370286400320Ø220Ø1808 x M1633LXF-150150500345500445Ø285Ø2408 x M2064 Changeover flow rate: ModelStarting flow Qx2closing flow Qx1m3/hLXF-801.80.7LXF-1002.11.2LXF-15064.2 Working condition: Water temperature:≤40°c Water pressure:≤1 Maximum permissible error: a.)In the lower zone from Qmin inclusive up to but excluding Qt is ±5% b.)In the upper zone from Qt inclusive up to and including Qs is ±2% Flow error curve: Pressure loss curve:
