Rotor wet type hot water meter LXS－15E～50E
◆Overview: The water meter is the meter that is used to meter the total volume of cold (hot) water in the tape water fully charged closed pipe.
◆Performance characteristics:
☆Multiple flow velocity, wide metering range, high metering precision, small startup flow rate, convenient reading.
☆It uses a high-quality corrosion-resistant movement that can ensure stable and reliable performance and long service life. Strong commonality of the meter ensures convenient replacement and repair.
☆The shell materials of the water meter include copper, gray iron, nodular cast iron, engineering plastics, stainless steel and aluminum alloy and other several materials.
※Based on order requirements, the model 15-20 cold and hot water meters with stainless steel meter housing can be provided without affecting flow errors.
◆Working conditions:
☆Water pressure：No more than 1．0MPa（10bar）
☆Water temperature: Cold water meter 0．1℃～50℃ Hot water meter 0．1℃～90℃
◆Indication Error：
a.The maximum permissible error in the low zone from the minimum flow inclusive to transitional flow exclusive is ±5%.
b.The maximum permissible error in the high zone from transitional flow inclusive to overload flow inclusive is ±2%, and is ±3% for a hot water meter.
