The piston movement is transferred by a magnetic coupling to the register which has the appropriate reduction gearing.• Applications Domestic consumption and green houses. • Available Sizes 1/2”, 3/4”.• Standards ISO 4064 (class C) and EEC metrological requirements.Features:• Specially designed for high accuracy and wide measuring range.• Sealed super-dry register.• The UK version includes: IP68 Pulse under the glass register.• Optional Electrical Output: EV, EF, Dialog 3G, DPE, MPE.DomesticMode l P - Po s i t i ve D i sp l a cemen t Wa te r Me te r DomesticModel M15(short) M15 M20Nominal size(mm) 15 15 20(inch) 1/2 1/2 3/4L – Length without couplings (mm) 165 190 190L – Length without couplings (mm) UK Version134 165L1 – Length with couplings (mm) 260 285 285B – Width (mm) 100 100 100H – Height (mm) 108 108 112Weight (kg) 1.40 1.50 1.75Weight with couplings (kg) 1.60 1.70 2.10DimensionsPerformance data:Model Nominal size(inch)Qmax Maximum flowrate(m3/h)QnNominal Flowrate (m3/h)QtTransitional Flowrate(l/h)QminMinimum Flowrate (l/h)Maximumregistercapacity(m3)Smallestreadable unit(liter)Accuracy betweenQmax & QtAccuracy betweenQt & QminQ15 1/2” 3 1.5 22.5 15 105 0.1 ±2% ±5%Q20 3/4” 5 2.5 37.5 25 105 0.1 ±2% ±5%• The meter can be installed in any position (horizontal, vertical or inclined) • The meter must be always full of water while operating.• Prior to the installation of a new meter, the pipeline must be flushed out.
