The water industry is exploring to uncover new technologies to aid increasingly sophisticated customer demands and improve productivity and operational efficiency. The industry is taking great efforts to ensure high levels of process reliability, consistent quality and accurate billing. There is also a swelling need to prove that operations are economically and environmentally sustainable. State-of-the-art measuring technology is the key to warranting these standards are met as it is important to ensure and maintain highly stable measurement over a long period of time.
Application segments in the water waste water industry, like the municipal waste water, desalination, utility water etc. have their individual requirements and regulations to meet. One common thread amongst all is that periodic, traceable calibration or verification need to be carried out to meet these requirements.
There are few towering challenges for carrying out calibration periodically.
Applications in the Water and Waste water industry often use large line sizes which makes it not feasible mainly due to the logistics involved with removing the flowmeter from the pipeline.
Any interruption of service or water supply is not acceptable.
Lack of calibration rigs, especially for large line sizes
Requires calibration rigs to be accredited according to ISO/IEC17025, which in some cases is not available at all.
The above-mentioned challenges are the main reasons why users are looking for an economical alternative to re-calibration.
When looking for economical substitutes, Verification process comes to the forefront. This process is used to verify and show that the device meets specific technical requirements defined by the manufacturer or customer.
However, there are certain quality regulations that this process needs to adhere to, namely;
Flowmeters must be verified at regular intervals
Verification must be performed by a qualified third party and with an accepted inspection
method based on quality regulations (ISO 9001)
A test report needs to be provided (documented proof of evidence)
In the past, for lack of any other verification system, it was always required to use a third-party external verification service provider. However, external verification is a very complex process that requires access to the measuring point in the field.
During verification, the transmitter is opened to input external signals using a special testing adapter. Verification is carried out by a trained technician with specific knowledge and requires approximately 30 minutes. The process also depends on the assembly and upkeep of the infrastructure.
The evolution of internal verification with the latest generation of flowmeters has made reliable internal verification technology available at your fingertips with time and cost savings and minimum efforts. Most importantly, it is a step into the world of digitalization!
Heartbeat Technology™ offers an unprecedented degree of diagnostic coverage from the measuring sensor to the transmitter output.
Traceable factory calibration and redundant internal references complement the safety-by-design principle that Endress+Hauser follows, with minimal failure rates in accordance with IEC 61508. Heartbeat Technology™ provides continuous self-monitoring without process interruption and diagnostic signal output according to NE107. Results of the test can be read out on site or remotely using an asset management tool and forwarded to electronic validation management. Data sets are stored on the device’s SD flash memory.
Benefits at a glance:
Heartbeat Diagnostics
Standardized diagnostic messages with clear instructions facilitate an efficient and status-oriented maintenance. Permanent self-diagnostics of the instrument enable a safe plant operation with extended verification cycles.
Heartbeat Verification
A guided verification procedure without interruption of the process achieves documented verification results. The automatically generated verification protocol supports the evidence required for regulations, laws and standards.
Heartbeat Monitoring
Trend recognition for predictive maintenance is easy to achieve with the provided instrument and process data. With a combination of device and process parameters you analyze targeted process optimization.
Digitalization in no more optional
In today’s competitive business, tackling the challenges of reducing costs, optimizing processes or increasing efficiency with yesterday’s solutions will not yield the required results to create a competitive advantage.
The Industrial Internet of Things (IIoT) has ushered in huge potential: predictive maintenance, asset information management and device configuration, situational analysis and real time flow & quality monitoring are just some examples of the opportunities digitalization has in store for companies.
On the other hand, customer behavior and expectations are also changing rapidly. More and more customers are proactively contributing to sustainability and reuse. More the digitization of utilities, easier it becomes to make and take informed decisions. Digitalization creates new opportunities at various levels.
Keeping an eye on all field devices
As part of the IIoT strategy, Endress+Hauser have developed very specific applications that integrate seamlessly into the existing plant technology and immediately provide the user with added value.
Smart Systems
Smart Systems are easy-to-use complete packages consisting of measurement technology, communication solutions and mobile apps. With these packages, you can access your important measurement data immediately, at any time and from anywhere. You can thus ensure ideal production conditions and good perspectives for success.
Health
With Health you let the assets in your production plant speak for themselves, so that you know immediately, at any time and from anywhere how your production facility is doing. If the assets aren't doing so well, you'll know what the reason is and what remedies and steps you need to undertake.
Library
Library makes the collective knowledge of your production facility available to all your employees immediately, at any time and from anywhere. You save valuable search time and archiving work.
Analytics
We have the digital service Analytics, which provides you with an inventory of your production facility within a few minutes and thus gives you complete transparency. Based on the inventory, current optimization suggestions for your production plant are calculated for you at any time.
“The IIoT ecosystem provides an opportunity to enter into a new relationship with the customers that goes beyond the sale of products. We want to accompany them through their journey of activities and demonstrate new ways with which to configure their processes more efficiently” says Laxman AR, Marketing Manager, Endress+Hauser – ME.
