HAC-MD_S External Two-way Low Power Wireless Valve Control Meter Reading System

HAC-MD_S External Two-way Low Power Wireless Valve Control Meter Reading System

HAC-MD_S External Two-way Low Power Wireless Valve Control Meter Reading System


System Introduction:

   HAC-MD_S system is designed according to the overseas customers?? special requirements for water and gas meter system. The working frequency range is 915-928MHz, it is suitable for American market. This system also can be customized for 470~510MHz for domestic market or 169MHz&868MHz for Europe market. 
   
   Statement: The wireless waking method for HAC-MD_S AMR system is the international invention patent owned by Shenzhen HAC Telecom Technology Co., Ltd.

System Feature:

Ultra Narrow-band, Frequency Hopping and Spread Spectrum Technology:
Narrow-band, high sensitivity, strong penetrability, frequency hopping, spread spectrum, anti co-channel interference, ensuring the communication distance and reliability.
Wide Working Voltage Range & Ultra Low Power Consumption Design:
HAC-MD_S module??2.8??6V DC, Static current??8??A, Average power-consumption??25??A,Max pulse current??70mA, valve control current??500mA.MD reports data every day and opens&closes valve once every half month automatically. Suppose  wake meter for meter reading and open&close valve once in every month, using 3.6Ah ER18505M power type battery, the actual using capacity is 50%, and the battery working life is more than 8 years.

Patented Waking Method??
a.HAC-MD_S module reports current metering data and state once in every 4 hours or in every 0.5m3
b.Concentrator reads meter data and controls valve. The concentrator or repeater can direct communicate with metering module, the visible distance is more than 2000m (LOS).
c.Handheld Terminal reads meter data and controls valve. The visible distance between Handheld Terminal and metering module is more than 1000m (LOS).
Wall-mounted Wireless Collector??
Easy for installation and using, flexible expansion. It can be used with multi-metering type water and gas meter, the battery can be changed.
Well-equipped & Fully Functional System:
The system includes HAC-MD_S collector, HAC-PDAD Handheld Terminal, HAC-RPD Repeater,  HAC-GWD Concentrator, HAC-MRD/P1 simple Concentrator and HAC-Sen series sensor collector.
HAC-MD_S collector includes wireless metering module, valve control circuits, interface terminals, battery and enclosure. It connects with water and gas meter with sensors. A HAC-MD_S collector can connect with some water and gas meters at the same time.
Valve Control:
HAC-MD_S module includes valve control circuits, it can connect with an external valve directly. Using Concentrator or Handheld Terminal can achieve remote wireless valve control.
Flexible Applications:
Connect with multi-metering type meter (Reed switch, Hall sensor and so on), Direct-reading meter (Customized). A collector can connect with some water and gas meters at the same time.
Customized special collector for the convenience of wireless transformation:
