Water Meter

Features This is the meter of the MW type structure meter that the flow water rotates the impeller through several classification holes near the inside in the bottom part, and its sensitivity is acute and meter range is wide. The classification holes in the inside of bottom part improves the sensitivity still more by selecting D nozzle and displays the superior performance in rainwater management. In spite of sharp of change of flow, this meter is excellent in precision and endurance.   Dimensions   Size   13(15) 20 25 32 40 50 Length of Meter I(mm) 165 190 225 230 245 305 Installation Length L(mm) 278 313 358 367 398 468 Height of Meter H(mm) 100 109 114 116 130 155 Installation Height h(mm) 27 33 35 40 44.5 59 Meter Connection Nut D(inch) PF 3/4 PF 1 PF 1 1/4 PF 1 1/2 PF 2 (ø70) Meter Connection Nut d(inch) PT 1/2 PT 3/4 PT 1 PF 1 1/4 PT 1 1/2 PT 2 Width of Meter B(mm) 95 100 100 100 117 138 Weight of Meter 1.1 1.7 2.0 2.3 3 4.5   Specification Type Tangent type , vane wheel type , multi water type Use Drinking water (water supply ) Temperature Available 0.3 ~ 30°C Pressure Available 0.3 ~ 10bar Precision ± 2% Installation Pattern Parallel installation (H)   Performance Flow(m3/h)   Standard(mm) 13 (15) 20 25 32 40 50 Max.
