IES Lean Systems Ltd. have a long history of working in Instrumentation. Some instrumentation examples IES Lean Systems Ltd. supplied to and commissioned for are:

Field & Analytical
Life Sciences
Mining & Minerals
Oil & Gas

Field & Analytical

IES Lean Systems Ltd. have been a supplier of Instrumentation and the provider of Automation Solutions for over 20years.
Partnering with “Blue Chip” Instrument manufacturers such as Siemens and Fireye we provide a comprehensive full lifecycle service covering supply, installation, commissioning, calibration and maintenance. Our engineering staff can provide an economic, full specification, loop and hook up design facility if required. From a single transmitter to a full “Turn Key” system, IES Lean Systems Ltd. is at your service.

IES Lean Systems Ltd. provides top line products such as the Siemens Sitrans family of Pressure, Level and Differential Pressure transmitters.


Instrumentation is a bewildering field for the uninitiated with a variety of techniques, an array of ancillaries, a multiplicity of materials, styles, packaging and communications. Which will be right and most cost effective for your industry and your application?

IES Lean Systems Ltd. can provide both the range of product and the depth of knowledge to answer those questions.

Other areas that we supply instruments for are:
Solid Flow
Mass Flow
US&R Level
Capacitance Level
Valve Positioner
Process Protection
Ignitors & Pilots
Flame Monitor
Ignitors & Burners


IES Lean Systems Ltd. implement instrumented solutions such as the MCERT scheme. ies has experience in CEMS (Continuous Emissions Monitoring) and CWMS (Continuous Water Monitoring). MCERTs are the Environment Agency's monitoring and certification scheme for emissions to Air, Land and Water, to protect the environment and human health. MCERT schemes are run by SIRA, an independent UK body, on behalf of the Environment Agency. They appoint approved MCERT Inspection companies for the Flow Survey, carry out the Management System Audit and issue MCERTs. From December 2008 all industrial companies within EU member states who use water or discharge effluent during their process must be working towards MCERT certification. They must identify who is responsible for flow monitoring, establish that flow monitoring is on their EPR (Environmental Permitting Regulations - formerly PPC Polution Prevention & Control) permit document and contact a suitable company to implement a solution. Flow monitoring must achieve +/- 8% uncertainity for the complete measuring system for the total daily volume for all flows included on the EPR (PPC) permit.

Currently there two methods of measuring flow:
-Open channel across a weir or flume closed pipe with a magnetic flow meter
-Closed pipe with a magenetic flow meter

Both methods will collect data via a controller type transmitter either for storage or for transmittion across a network to a plant wide control system where it can be retrieved in an appropriate format upon an EA inspection.
Companies are required to have their site inspected under the MCERT Self Monitoring of Effluent Flow scheme. If their flow monitoring and site management systems are sufficient they need to ensure ongoing performance is adequate by an inspector who will apply to SIRA for an MCERT Site Conformity Inspection Certificate.

There are 3 basic elements to the process:
Flow Survey
Management System Audit
SIRA review of evidence

The Flow Survey and Quality Management Audit will be by 3rd party with ies providing remedial action: either structural or equipment supply if required, along with assistance prior to the audit and regular site visits to maintain MCERT standards.
ies can provide overall control of the whole process giving you the ease of using one point of contact.
