2. Product Description
CASCADEMIC Smart Water Meter Solution is a compact low power Industrial grade device that has the
features to work under a networked environment.
The Smart water meter has inbuilt Processing, storage and RF transmission unit. The Smart water meter is
an automated meter reading (AMR) based water meter which is integrated and can be completely sealed
based on the application requirement.
The modular approach design of this device provides the OEM’s
the flexibility to use any type of sensors that match their application
environment. For the current remote water flow meter application,
we can use ultrasonic sensor, AMR sensor or Hall Effect Sensor.
It’s works on the principle of
Hall Effect sensor where the
rotation of the magnet is
converted to pulses and water
flow is calculated.
It’s easy to install in all areas
and can be mounted either
horizontally or vertically
It can be external Powered or
can be powered completely
through battery our current
solution is field tested for the
operation duration of 1.5 year
with 1 Ah battery.
It has the inbuilt capabilities to
detect LEAK, BURST, TAMPER,
DRY, and REVERSE flow.

3. LoRa™ Why do we use Lora in CASCADEMIC Metering Solution?
Block Diagram
Lora use Digital proprietary nodulation based on DSSS with constant envelope modulation.
Supports all major sub-GHz bands
- 169 MHz, 433 MHz, 470 – 510 Mhz (China), 868 MHz and 915 Mhz
Completely asynchronous
Provides receiver sensitivity upto -148 dBm
It can achieve upto 5 Kms in suburban environment and 2 to 5 Kms in dense urban environment.
The additional range provided by LoRa eliminates the need for repeaters in these applications
Superior co-channel interference robustness.
Simultaneously it can receive from multiple channels.

4. Wireless M-bus features
It has been designed to meet the future
needs to work under various hazardous
environments and it is optimized for
ultra low power, RF friendly, high
efficient operation.
Way of communication
Supports bidirectional communication.
The measuring equipment sends the
data based on the Concentrator Ping
message or through a predefined data
protocol at set intervals.
Performance and data security
Three different performance classes of
transceivers are defined in the wireless
M-Bus standard and the stack is fully
compliant with all the modes. AES-128
(encryption) is provided for data security.
Using CASCADEMIC Remote metering
technology the processed and stored data
from the meter is transmitted through
the concentrator to the network. There is
no need for appointments or home
inspections.
Wireless M-bus
wireless remote meter reading system
CASCADEMIC have specially developed along with our partner
and Integrated smart communication system for the remote
monitoring of water meters.

5. Smart Water meter Solution
Hardware Description
Controller board
The processor used in SWM is Freescale kinetis L series
processor which is an Ultra low power processor. The core
used is ARM cortex M0+. This processor contains various
power modes such ad Run, sleep and deep sleep. The
maximum RAM capacity available is 32 KB and flash is 256 KB.
Sensor board
The hall sensor can sense magnetic field upto 3mTesla and
can detect upto 20 rotations per second.
A Hall effect sensor is a transducer that varies its output
voltage in response to a magnetic field. The rotation of the
magnet is converted to pulses and water flow is calculated.
Hall effect sensors are activated by a magnetic field and
device can be operated by a single permanent magnet
attached to a moving shaft or device.
RF board
Our current solution of RF board supports LoRa (long range).
SX1276 and LoRa:
Our RF board incorporates the LoRaTM spread spectrum modem.
It is Completely asynchronous.
Provides Receiver sensitivity up to -148dBm.
Superior co-channel interference robustness. Signal recovered
below interference level – jammer resistant.
>69dB adjacent channel rejection.
LoRa bit rate from 300bps to 40Kbps
LCD board
A customized LCD solution with low power consists of
8 digit, measuring unit and information code is used in SWM.
The display appears as below:

6. WHY
CASCADEMIC
Smart water meter
solution?
LOW POWER
SWM is a low power water meter which can
operate for 1.5 year with 1 Ah battery.
The processor used Ultra low power processor
and it is operating in deep sleep mode when
there is no water flow and switch between deep
sleep and run when there is water flow.
The Low power board and system design -
very less power consumption (few microA).
The RF Module consist of various power
mode and it is operated in least power mode so
that the overall power consumption is reduced.
INFO CODE
LEAK:
If water flow is registered continuously for 24
hours, then this LEAK code will be detected
BURST:
For the given value of continuous 30 minutes if the water flow
exceeds that value then BURST will be detected.
TAMPER
This information code will be activated when some unauthorized
person try to open or access the water meter. If once this
code is activated then the meter will no longer be used for
billing and other code will not be send through WMbus.
DRY:
This code is activated if there is air in meter.
REVERSE :
When the water in meter flows in reverse
direction this code will be activated.
RADIO OFF:
If the meter reading is not sent through
WMbus this code will be activated.
CONCENTRATOR
The concentrator box consist of
Freescale kinetis L series processor board.
RF module which contains LoRa Technology.
It can handle upto 72 meters connected to it
The concentrator can communicate to the utility provider
through GSM, 3G or WAN.
This setup will be powered using USB adapter and a back
up battery will be provided in case of power failure.

7. TARGET APPLICATIONS
This technology can be incorporated in a simple
coffee machine to a large industry.
The meter can be used in various industries such as
petroleum, chemical, medical, water purifying
industry etc.
The meter can be installed in apartments to get
the amount of water consumed by the apartment
and each homes.
This technology is applicable to all the metering
application.

8. In the era of the smart technologies ,where the convergence of the technologies extending from our
phones and PDA's to the standalone intelligent devices, we at CASCADEMIC extended and evolved our
decades of embedded fables ODM expertise from the SCADA to the M2M & IoT space.
CASCADEMIC Solutions is a Fabless ODM in M2M and IoT Space
In the process of continuous evolution of technology, the process and processor SoC’s are evolving
and becoming more and more capable ,faster and smaller than ever before. The distance between
the countries is narrowed down as well as the devices connected in it.
At this changing phase of technology where integration of technology is extended till the final end
devices – We are today connected to everything around us and we at CASCADEMIC extended that
connectivity to our home water problems.
Our OEM Smart water meter solution is an ideal solution for the monitoring and controlling of the
water flow remotely, with the advanced technologies such as LoRA and Wireless M Bus. We make
devices to connect and communicate to the human connected world
