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).

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.

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 anti-interference performance and other characteristics.

meter has photoelectric, Cat1, Rs485, bluetooth multiple communication interfaces, can be used directly with infrared read/write

head to read/write data, can also be used to configure the instrument parameters and RS485, Cat1 and other communication

parameters.

has menu displays such as common interface, detection interface, data information interface, error information interface, Cat1

information 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;

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;

valve mechanism includes: valve body, actuator and drive circuit, valve body valve body using rubber lined butterfly 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.

Intelligent management system can realise intelligent management such as remote control, flow rate adjustment, forced switching

of valves and so on;

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.

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
