CASCADEMIC SMART WATER METER

Ultra Low Power

Long Rang(LoRa)

Multiple meter connectivity

Able to detect Leak, burst, dry, reverse flow and tamper

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.

Detection Capabilities

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.

Wireless M-bus featuresIt has been designed to meet the future needs to work under various hazardousenvironments and it is optimized for ultra low power, RF friendly, high efficient operation.

Way of communicationSupports 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 securityThree 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 meteringtechnology the processed and stored data from the meter is transmitted through the concentrator to the network. There isno 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.

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 boardThe 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 outputvoltage 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 boardOur 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 boardA customized LCD solution with low power consists of8 digit, measuring unit and information code is used in SWM.

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 detectedBURST:For the given value of continuous 30 minutes if the water flow exceeds that value then BURST will be detected.TAMPERThis 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.

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 apartmentand each homes.

This technology is applicable to all the metering application.

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
