Combination Water Meter
FUNCTION:Measuring the volume of cold or hot water passing through the pipeline.FEATURE:In- line type of water meter comprising one large flow rate meter.one small flow rate meter and a change over device that depending on the magnitude of the flow rate passing through the meter automatically directs the flow through either the small or large meter or both. So the flow rate range of the meter compared with other types of meter is more widely. It is easy for maintenance for its removable measuring unit and directly magnetic coupling transmission. For the small meter, the wet dial register type and the liquid-sealed register type are on option.HYDRAULIC PERFORMANCESizemm5080100150inches2´´3´´4´´6´´Metrological class R(Q3/Q1≤1250) Q2/Q1≤(1.6、4)Q3m3/h2563100250TECHNICAL SPECIFICATIONSMaximum permissible error±5%between Q1and Q2(excluded)Maximum permissible error±2% with water temperature≤30℃between Q2(included)and Q4±3% with water temperature>30℃Temperature classCold water:0℃ 40℃ Pressure loss class△p63Nominal pressurebar10/1610/1610/1610/16Min readingm30.000050.000050.000050.00005Max readingm<(unknown) id="0" class="font1">(unknown)999,999999,999999,999999,999DIMENSIONSLmmWmm310330445HmmCONNECTING BOLTSOutside diametermmBolt circle diametermmConnecting bolts4-M168-M168-M168-M20
