Based on no moving parts electromagnetic technology, SmartMeterTM is not affected by wear (and the subsequent inaccuracy caused by mechanical wear) even in areas where grit and sand are an issue. The meter’s advanced sensing technology also delivers extended operational life with long term accuracy. Its unique air detection system prevents measurement of air flow, which can occur at high points in the water network and at the start of water delivery. The robust new Fortron (PPS) base is totally resistant to acid/corrosion attack in all water conditions. The material has excellent properties of tensile strength, hardness and surface integrity. It can be used with brass and other metallic fittings.
