IWS Remote Temperature Monitoring System

Comprehensive System management and Legionella risk monitoring at your fingertips

Integrated Water Services’ remote monitoring solution offers a real-time, global overview of the water system. Complimenting a traditional approach to manual monitoring, Legionella control temperatures, system schematics and scheme of control are readily available through an online portal giving full visibility and instant alerts to out of specification measurements.

Corrective actions initiated and system changes are tracked by the software giving a full audit trail to support any control scheme. Using our continuously improved hardware and cloud-based software, the simple and easy to install LoRaRF temperature sensors provide constant feed-back on system utilisation, exceeding the requirements of HSG274 pt2.

System Overview

The IWS Water Hygiene range of wireless RF transmitters combine local data collection with remote configuration and monitoring via the Realtime Online™ web interface. All transmitters link to the web via the Integrated Water Services LoRa RF IoT GSM Gateway, providing standalone and secure access, independent of the client’s network infrastructure.

Remote temperature monitoring

System Specification

  • Connection for up to three external temperature probes
  • Typical accuracy of ±0.5°C (UKAS reference)
  • Temperature range of -40°C to +125°C max
  • LoRaWAN version available
  • High and low thresholds
  • Built-in antenna or SMA connection available for remote external antenna connection

Ensuring water safety …

Traditional manual temperature monitoring satisfies minimum guidance, but essentially confirms only the capability of the water system to reach required temperatures, not that they are consistently achieved.

Temperature data, measured by our sensors installed around the water system of the building, is received by the GSM Gateway. The gateway transmits real time data via GPRS to our secure cloud server. Graph production and visualisation tools help expose potential risks, understand contributing factors and highlight opportunities for increased efficiency.

Our system captures the high and low temperatures relevant to critical requirements that often go undetected by manual temperature checks or intermittent readings. Alert levels are tailored to individual systems and exceptions are communicated via text or email. This provides escalations and notifications of out of specification results, in real time, allowing immediate inspection and resulting in earlier issue resolution and a safer water supply.

  • Long Range wireless RF sensors
  • Non-intrusive monitoring
  • Automatic and continuous measurement
  • Long battery life
  • Expandable and simple to use
  • Readily accessible

Benefits

  • Level of monitoring vastly increased from manual visits
  • Restricted or difficult to access areas continuously monitored
  • Low maintenance costs
  • Exceeds requirements of HSG 274 pt2
  • Improved demonstration of compliance
  • Ongoing accuracy confirmed by validation visits.

 

Reassurance

The system exceeds all requirements of HSG274 Part 2 with the additional benefit of a document upload and storage facility, therefore proving a single source and easy to access resource for your Legionella Compliance.

Clients gain peace of mind over the condition of their water systems, ensuring the risk from Legionella Bacteria and Legionnaires’ Disease is minimised

Installation Process

Interrogation of the site legionella risk assessment, site survey and consultation with site responsible managers will confirm the system locations to be monitored. Installation is carried by IWS engineers and readings validated against calibrated temperature probes. Portal access and alert criteria are then established and monitoring is live.

Validation of data

IWS carry out (initial) quarterly validation visits where manual readings are taken to ensure the remote data is accurate. Sensitivity gain on the probes can be altered, allowing different pipe materials and external influence to be factored out.

Ongoing Support Services

In addition to validation visits, IWS can offer several supplementary levels of support, where both dashboard and individual probe data is interrogated for potential issues that may increase risk from the system.

Schematics

  • Water schematic displays points monitored
  • Sensors displayed are live and show the most recent temperature
  • Clicking on any sensor will access the graph for that sensor

Reports

  • Weekly exceptions
  • Weekly compliance
  • Weekly exceptions escalated
  • Monthly compliance
  • Failed sensor notifications
