Product Features：
1.large diameter flow sensor using ultrasonic flow measurement principle design,transducer components using high-quality piezoelectric ceramic sensors, circuit components using ultrasonic flow measurement of special chips and matching embedded software, to ensure that the flow measurement part of the wide-range ratio, high-precision and stability and reliability; flow measurement of the specific performance indicators see the fourth article (technical indicators).
2.large diameter flow sensor structure parts without any mechanical movement, no wear and tear, not easily affected by water quality and low maintenance costs, with stable work, long service life and other advantages.
3.The main chip of instrument adopts professional chip as microprocessor, advanced micro-power consumption design, with large programme capacity, rich functional pins, small quiescent current, strong
4.Meter has photoelectric, Catl, Rs485, bluetooth multiple communication interfaces, can be used directly with infrared read/writhead to read/write data, can also be used to configure the instrument parameters and RS485, Cat1 and other communicatior parameters.
5.Meter has menu displays such as common interace, detection interface, data information interace, error information interface, Catinformation interface, etc. it can display flow rate, flow velocity, water temperature, pressure, valve status switch angle, time,calibre as well as the instrument's working status and faults and other information.
6.Data storage function:this meter can store the daily freeze data, can store the daily cumulative, monthly cumulative and other historical data of the instrument.
7.Valve mechanism includes: valve body, actuator and drive circuit,valve body using rubber lined butterly valve, valve actuator using a large reduction ratio mechanism (25900:1), torque ≧ 100NM, actuator operating voltage 2.5 ~ 6v, drive circuit using a special high-current drive chip and match with the protection of the electronic devices, The overall valve mechanism is flexible to open and close, can respond quickly, long service life, safe and reliable, the valve can perform switching action, can also be adjusted angle to achieve the specified flow rate.
8.Intelligent management system can realise inteligent management such as remote control, flow rate adjustment, forced switchingof valves and so on.
9.With self-maintenance function: the valve body can be automatically switched on and off according to the setting of staggered time, automatic sewage washing valve function, remove the scale formed inside due to long-term inactivity, to avoid the phenomenon that the valve can not be switched on and off.
10.Valve has a manual self-integration function in the power outage or failure can use special tools to open or close the valve through mechanical devices.
