MCERTS approval for Rosemount pH
analysers
Rosemount pH analysers and sensors, used to monitor process conditions and discharges to rivers, smaller watercourses and the sea in England and Wales, have gained MCERTS approval
The recently awarded MCERTS certificates were issued by Sira, who operate the scheme in England and Wales on behalf of the Environment Agency The approvals cover any combination of Rosemount Analytical Xmt, 54e, 1055 and 5081 transmitters with 399, 399VP and 381+ sensors from Emerson Process Management

Upgrading possible for old DCS systems.
New connection, control and display migration products from Emerson permit the easy and rapid conversion from older generation automation systems to the new PlantWeb digital plant architecture.
These products have been tested and found to comply with the required Environment Agency performance standards for continuous water on-line analysers.
Emerson Process Management is currently the only company to have successfully obtained MCERTS approval for pH analysers and sensors, and this involved working closely with the Environment Agency throughout the process.
Businesses that make emissions to air, land and water are regulated by the Environment Agency under strict European, English and Welsh laws, to protect the environment and human health.

Permits are issued to enable companies to operate and this normally requires emissions to be monitored to ensure they meet the necessary quality standards.
"Operators are being increasingly required to continuously monitor their discharges and provide valid records to us," said Paul Wiggins, Technical Adviser, of the Environment Agency: "Cornerstone to this scheme is the confidence that the records submitted are from an instrument that is both accurate and reliable.
Data from an instrument which has MCERTS approval will normally be accepted without any further evidence being required, allowing operators to run their businesses in the most efficient way.
Our policy is that where MCERTS equipment is available and appropriate, we expect operators to install it".
In order to be granted MCERTS approval, analysers are performance tested in the laboratory, and must undergo three months of field trials - or the manufacturer must submit field data from existing installations - in order to assess factors such as accuracy, repeatability, linearity and long term stability.
To meet the requirements for field data, Emerson used the records from a Scottish and Southern Energy (SSE) installation at Keadby Power Station near Scunthorpe, where Rosemount Analytical sensors are used to continuously monitor the pH of water which is extracted from the river and used for cooling.
The on site laboratory had been analysing samples independently so that direct comparisons could be made between the laboratory results and instrument readings.
"We appreciate the assistance that the the SSE Team at Keadby Power Station have given us in helping Emerson gain MCERTS approval," said Stephane Canadas, Business Development Manager for Emerson Process Management: "Emerson is committed to ensuring that its products meet the latest industry standards.
Using products with MCERTS approval brings many operational benefits for our customers while ensuring their operations meet strict environmental standards".
"By submitting its products for independent testing, Emerson has demonstrated its confidence in the performance of the Rosemount Analytical analysers," said Paul Wiggins: "Emerson has worked closely with the Environment Agency and Sira to help develop this particular scheme and we are pleased that these products have been awarded MCERTS certificates".
The MCERTS Scheme is formally recognised in England and Wales and accepted internationally.
It provides instrument manufacturers with an independent authoritative endorsement of the practical performance of individual products. Request a free brochure from Emerson Process Management ...
