HAC-RHU Handheld Terminal

HAC-RHU Handheld Terminal

HAC-RHU Handheld Terminal

System Products:
 Connect to android phone through Bluetooth.
Set parameter like meter ID, initial water quantity, pulse constant to HAC-MD within 10cm range, without disassembly.
Set the Repeater power, Repeater working channel and Concentrator working channel within 50m range.
 Waken HAC-MD module to finish meter reading and valve control, 1500m (LOS), using for reading the meters in communication blind district.
 
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:
 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:
 The patented waking method will not have mistake waken and its power consumption is controllable. The waking window is less than 3ms, comparing with traditional waking window, it shortens 50% to lower power consumption effectively. The waking and meter reading period for Handheld Terminal and Concentrator is 8s, it can meet real-time requirements.
Mulit Metering Mode:
 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 1500m (LOS).
 Valve Control:
 HAC-MD module includes valve control circuits. Users can use Concentrator or Handheld Terminal to wireless control valve, which is convenient to expand the prepaid valve control function.
 Well-equipped & Fully Functional System:
 HAC-MD Transceiver: Single Reed Switch/Double Reed Switches Metering mode, Direct-reading mode (Customized), two-way communication, Soft clock, Power management, Break line detection, Anti-magnetic, Anti-disassembly (Customized).
