-
Key Applications: Their solutions are actively deployed for vaccine and ultra-low temperature freezers, cold storage, pharmaceutical warehouses (such as Imexpharm), cleanrooms, and pipeline pressure monitoring—providing automated reporting and multi-channel alerts (SMS, phone calls, mobile push, and email).
Below, we would like to present their hands-on experience and insights in the field of remote pressure monitoring.
PROBLEM TO SOLVE / TASK
Pressure sensors are installed in water, oil, chemical, or compressed air pipelines for continuous pressure monitoring. In the event of a pressure issue, a PLC controller operates a pump or valve to immediately increase or decrease the pressure. However, most pressure sensors only provide control signals and lack alerting capabilities.
As a result, early detection of issues outside working hours remains extremely difficult. This is particularly critical in water treatment plants, where water supply pipelines operate continuously, making 24/7 automated pressure alert solutions essential.
Comparing local on-site indicators with remote 24/7 pressure monitoring
In industrial facilities, pipeline pressure is typically monitored using mechanical or electronic pressure gauges, with pressure switches used to trigger local warning lights and alarm sirens. However, this system is only effective when staff are physically present on site. Outside regular working hours, these local alerts become useless.
Pressure warning via mobile app
Therefore, a 24/7 pressure monitoring system that delivers instant notifications to mobile phones is an essential solution.
The comparison table below highlights the key differences between these two methods:
| Comparison Criteria | Local Alerting | Remote Mobile Alerts |
| Fault Detection Capability | Requires staff to be present on site | Automatic detection and instant alert sending |
| Incident Response Time | Depends on the frequency of manual inspections | Immediate notification |
| After-Hours Coverage | Ineffective | Fully operational 24/7 |
| Pressure History Tracking | Manual handwritten logs | Automated data archiving |
| Managing Multiple Points | Difficult and labor-intensive | Simple – all data displayed on a single platform |
| Trend Analysis | Not feasible or very limited | Detailed charts and analytical reports available |
| Long-Term Operating Costs | High | Low |
Easily monitor pipeline pressure using the app
SOLUTION
To implement their remote monitoring projects, TIN VIET ENGINEERING TECHNOLOGY COMPANY LIMITED. chose the automated pressure monitoring and alert system developed by the Polish brand Efento. Operating in over 40 countries worldwide, this solution is widely recognized for its reliability, speed, and precision.
When safe thresholds are exceeded, the system delivers multi-channel notifications, including:
-
Simultaneous voice phone calls to multiple users,
-
SMS notifications sent to selected phone numbers,
-
Instant push alerts in the mobile application,
-
Email notifications sent to an unlimited number of recipients.
Beyond basic alerting, the solution offers advanced notification configuration features:
-
Recurring alert repeats (e.g., every minute) until action is taken,
-
Configurable time delays before sending alerts (to prevent false alarms during temporary pressure spikes),
-
Alarm level categorization (e.g., warning vs. critical levels),
-
Automatic notifications when pressure returns to safe limits.
The system also includes comprehensive analytical and management tools that simplify daily oversight and trend analysis:
-
Minute-by-minute measurement history recording,
-
Automated generation and email delivery of daily reports and trend charts,
-
A dedicated real-time pressure dashboard,
-
Granular user permission management,
-
Multi-sensor management on a single unified platform,
-
Free, unlimited access via both the mobile application and web browser.

Pressure Monitoring Options by Efento
Efento offers two primary system architecture options:
1. NB-IoT – Direct Cloud Transmission (SIM Card)
The smart Efento NB-IoT logger features a built-in SIM card and connects directly to the Efento Cloud platform.
-
Battery Life: A high-capacity battery (6,300 mAh) paired with power-saving modes provides up to 10 years of maintenance-free operation.
-
Costs: Requires a periodic SIM data plan subscription fee.
-
Best For: Ideal for outdoor pipelines or remote sites far from network infrastructure—operates fully independently without external power or additional hardware.

2. BLE (Bluetooth Low Energy) – Gateway Transmission
In this setup, the logger wirelessly transmits data to a gateway (LTE or Ethernet), which then forwards it to the Efento Cloud.
-
Costs: No individual SIM fees per sensor—multiple loggers can share a single gateway.
-
Benefits: High connection stability and a lower cost-per-point in larger deployments.
-
Best For: The most cost-effective choice for indoor installations (e.g., production plants) where network infrastructure or power for the gateway is available.

Frequently Asked Questions (FAQ)
Can the system detect pipe leaks?
Yes. A leak causes a rapid pressure drop. When readings fall below the configured safe threshold, the system immediately triggers an alert so maintenance personnel can inspect the site promptly.
Can multiple geographically separated sites be monitored?
Yes. The Efento platform enables centralized management of hundreds of pressure sensors across different branch locations from a single dashboard.
Does the alert system work during a power outage?
Yes. Sensors are battery-powered and operate fully independent of the main power grid. In NB-IoT setups, data transmission continues without interruption.
Is cellular communication (NB-IoT / LTE) reliable?
Yes. These technologies leverage commercial cellular networks with nationwide coverage, ensuring stable and secure telemetry transmission.
Is historical pressure data saved for future review?
Yes. All measurement data is securely stored in Efento Cloud for up to 6 years, allowing you to access and analyze historical trends at any time.
