Water management is becoming increasingly important for residential communities, commercial buildings, industrial facilities, and municipal infrastructure. Traditional water monitoring methods often depend on manual inspections and locally installed control systems. These approaches can make it difficult to monitor multiple storage locations, identify water shortages, and coordinate water distribution efficiently.

NB-IoT (Narrowband Internet of Things) technology offers a wireless communication option for connecting water monitoring devices to digital platforms. When integrated with a tank level transmitter, NB-IoT enables water-level measurements to be transmitted to remote monitoring systems, helping facility managers access tank information without frequent physical inspections.

By combining a suitable Water tank level sensor, a Smart IoT Edge Gateway, and a cloud platform such as the MyTank IoT Platform, organisations can develop connected water infrastructure with improved monitoring and operational visibility.

Understanding NB-IoT Technology in Water Monitoring

NB-IoT is a cellular communication technology designed for Internet of Things applications. It operates through supported mobile network infrastructure and is intended for devices that transmit relatively small amounts of data.

In water infrastructure, NB-IoT can connect level monitoring devices installed in storage tanks, reservoirs, and other water storage facilities to remote monitoring platforms.

Its important characteristics include:

• Low-power communication: Designed for connected devices that need to transmit small amounts of data efficiently.

• Wide-area connectivity: Uses supported cellular networks to connect devices across geographically distributed locations.

• Indoor coverage: Designed to support communication in challenging indoor environments, subject to network availability and deployment conditions.

• Scalability: Supports large-scale IoT deployments through compatible network infrastructure.

• Remote data transmission: Enables sensor readings to reach central monitoring platforms without requiring a dedicated local wired connection to every monitoring location.

NB-IoT availability and performance depend on mobile network operator support, geographical coverage, device compatibility, and deployment conditions.

How an NB-IoT-Based Tank Level Transmitter Works

An NB-IoT-based tank level monitoring system combines measurement hardware with wireless communication capabilities.

A typical operating process involves the following steps:

1. Water-level measurement: A tank level transmitter measures the water level inside a storage tank.

2. Signal processing: The device processes the measurement and prepares the reading for transmission.

3. Wireless communication: The NB-IoT-enabled device sends the data through a supported cellular network.

4. Cloud data reception: A connected platform receives and processes the incoming information.

5. Dashboard display: Facility managers access available readings through a web dashboard or mobile application.

This process allows users to monitor water storage remotely and review the latest available measurements.

The exact architecture depends on whether NB-IoT connectivity is built directly into the transmitter or provided through an external communication device.

Choosing the Right Water Tank Level Sensor

The sensor is one of the most important components of a digital water monitoring system. Its measurement accuracy and suitability directly affect the quality of the information received by the monitoring platform.

Different sensor technologies can be considered based on tank dimensions, installation conditions, and application requirements.

Radar level sensors

Radar sensors use electromagnetic waves to measure the distance between the sensor and the water surface. They provide non-contact measurement and are suitable for many industrial and commercial water storage applications.

Ultrasonic level sensors

Ultrasonic sensors use sound waves to determine the distance to the water surface. Their performance can be influenced by temperature, vapour, condensation, and obstructions.

Hydrostatic level sensors

Hydrostatic sensors measure liquid pressure to calculate the water level. They are commonly considered for applications where contact-based measurement is suitable.

Float-based sensors

Float sensors use a mechanical floating mechanism to detect specific water-level positions. They are often used for basic level detection and control applications.

When selecting a Water tank level sensor, consider its measurement range, installation requirements, power consumption, environmental suitability, and compatibility with the communication system.

The Role of a Smart IoT Edge Gateway

A Smart IoT Edge Gateway acts as an intermediary between connected field devices and central cloud platforms in suitable IoT architectures.

It can collect information from multiple sensors, process data locally, and forward the required information to cloud-based applications.

In smart water infrastructure, an edge gateway may support several functions:

• Device connectivity: Connects compatible sensors and field equipment.

• Protocol conversion: Helps devices using different communication protocols exchange information.

• Local data processing: Processes selected measurements or events closer to the source.

• Data transmission: Transfers collected information to cloud platforms through available network connections.

• Communication management: Supports monitoring and coordination of connected devices.

• Network integration: Helps integrate field equipment with broader monitoring infrastructure.

For example, a facility may have several water tanks equipped with wireless sensors. A compatible gateway can collect readings from these devices and forward the information to a central monitoring platform.

However, an edge gateway is not required in every NB-IoT architecture. Some NB-IoT transmitters communicate directly with the cellular network and send readings to the cloud without a separate local gateway.

The choice depends on the sensor architecture, communication technology, and system requirements.

How NB-IoT Supports Smart Water Infrastructure

Smart water infrastructure involves connecting sensors, communication networks, monitoring platforms, and automation equipment to improve water management.

NB-IoT can support this approach by connecting remote water storage locations to centralised digital systems.

Important applications include:

Remote reservoir monitoring

Municipalities and water management organisations can monitor reservoir levels from central locations, depending on sensor and network deployment.

Apartment and residential water management

Facility managers can monitor underground sumps and overhead tanks to understand water availability and plan refilling operations.

Industrial water storage

Industrial facilities can monitor process water storage tanks and support more structured water management activities.

Agricultural water management

Connected level monitoring can help farmers understand water availability in storage tanks used for irrigation.

Commercial building management

Hotels, hospitals, offices, and shopping complexes can use connected monitoring systems to improve visibility into their water storage operations.

Cloud-Based Data Monitoring and Analytics

Once the sensor readings reach the cloud platform, they can be organised and displayed through digital dashboards.

Cloud analytics helps transform individual water-level measurements into information that supports operational decisions.

Depending on the platform's capabilities, users may be able to:

• View the latest available water levels across connected tanks.

• Compare water-level changes over time.

• Identify unusual changes in storage levels.

• Configure notifications for selected high-level and low-level conditions.

• Review historical measurements where data retention is supported.

• Monitor multiple locations through a central interface.

• Support water distribution and pump operation planning.

For example, a facility manager responsible for several buildings can use a central dashboard to review tank readings instead of visiting each location individually.

This improves operational visibility and can help maintenance teams identify potential issues earlier.

Integrating Tank Monitoring with Water Automation

NB-IoT-based monitoring can also be part of a broader water automation system.

When connected with compatible controllers and electrical equipment, water-level information can support automated pump and valve operations.

Possible applications include:

• Starting or stopping pumps based on configured water-level conditions.

• Monitoring underground sump and overhead tank levels.

• Supporting overflow prevention through suitable control logic.

• Coordinating water transfer between storage locations.

• Providing remote visibility into connected pump systems.

For safe operation, automation requires compatible controllers, appropriate electrical protection, correct configuration, and suitable installation. A monitoring sensor alone does not automatically control a pump.

How MyTank IoT Platform Supports Connected Water Management

The MyTank IoT Platform by Elint Systems is designed to support wireless water tank monitoring and automation through connected sensors, mobile access, and cloud-based monitoring.

Its capabilities include:

• Wireless radar-based water-level monitoring.

• Sump and overhead tank monitoring.

• Mobile application and cloud dashboard access.

• Monitoring of up to 256 tanks remotely, depending on system configuration.

• LoRa-based communication with connectivity of up to 5 km under suitable conditions.

• Wireless pump automation using compatible single-phase and three-phase smart starters.

• Automated valve control in supported configurations.

• Water quality monitoring through compatible sensors.

For NB-IoT deployments, it is important to verify the compatibility of the selected transmitter, communication module, network, and cloud integration requirements. MyTank's available connectivity options should be confirmed for the specific project before selecting an NB-IoT architecture.

By bringing monitoring and automation functions together, MyTank can help residential communities, commercial buildings, industrial facilities, and agricultural operations improve their water management processes.
