A water meter, is the measurement of water flow meter, mostly water cumulative flow measurement, generally divided into two categories of the volumetric water meter and the velocity water meter, originated in the United Kingdom, and the development water meter has nearly two hundred years of history, the choice of water meter specifications, should first estimate the size of the flow rate and flow range used under normal circumstances, and then choose the common flow rate closest to the value of the kind of specifications of the water meter as the first choice.
(1)Removable element structure, easy installation and maintenance, register for universal use within this rangedetachable without removing the meter from the pipeline.
(2)Dry-dial, Magnetic drive sensitive action, small pressure loss.
(3)Vacuum sealed register ensures the dial keeps free from fogand Keep the reading clear in a long term service.
(4)Selected high quality materials for steady & reliable characteristics.
(5)Technical data conform to international standard lSO 4064.
(1)Plastic register, copper register and full glass register.
(4)Cold / Hot water.
(5)Reed switch option.
(6)Flange standards can be chosen.
(7)360 degree rotates can be chosen.
(8)Cast iron, ductile iron, sS304, sS316 body can be chosen.
(9)Working pressure: PN16/25.
(10)Color can be changed on the body and cover.
(1)Water temperature: 0.1 C~40C for cold water meter.
(2)0.1C~90C for hot water meter.
(3)Water pressure: PN10/16/25.
Maximum Permissible Error:
(1)ln the lower zone from qmin inclusive up to but excluding qt is ±5%.
(2)ln the upper zone from qt inclusive up to and including qs is ±2%(士3% for hot water meter).
