Product Description

DEFINITION: Set of moving device that fitted into a closed conduit driven directly by water flow. Its turbine rotor rotates about the axis which is perpendicular to water flow. WORKING PRINCIPLES: Water flow drives vane rotate. Rotating times which is proportional to water flow speed are gathered, hence total volume passed through water meter is recorded. CHARACTERS: Types: Wet, dry, vertical, liquid sealed. Wide measuring range, high accuracy. Stable measuring capacity Long working life Low pressure loss All technical figures are conformed with GB/T778. 1~3-1996 which is equivalent to ISO4064 Standard Class B. WORKING CONDITION: Water temperature≤45ºC(Hot water meter≤90ºC) Water pressure≤1Mpa MAXIMUM PERMISSIBLE ERROR: From the minimum flow-rate (qmin) inclusive to the lower zone of the transitionalflow-rate (qt) exclusive: ±5%. From the transitional flow-rate (qt) inclusive to the higher zone of the maximum flow-rate (qmax) exclusive: ±2%(hot water meter±3%. ) DN/Q Q4=1.25Q3    Q3 R=Q3/Q1 Q2=1.6Q1    Q1 R=Q3/Q1 Q2=1.6Q1    Q1                l/h               l/h            l/h    15        3125 2500         80         50   31.25      100        40    25    20        5000 4000         80         80   50      100        64    40 Nominal size DN (mm) Class of measurement Overload flow-rate q  s (m 3 /h) Permanent flow-rate q  p (m 3 /h) Transitional flow-rate q  t (l/h) Minimum flow-rate q  min (l/h)        15            B          3          1.5          120         30        20            B          3          1.5          200         50 Overall dimensions and weight Type Size (mm) Length (mm) L Width (mm) W Height (mm) H Connecting Thread D Weight(kg) LXSG(R)-13D4     15 110/115        77        80       G 3/4"B    0.78 LXSG(R)-20D4     20 110/115/130        80        80       G 1"B    0.98
