Accurate flow measurement is vital throughout the process industry. In many process applications, density is used for process control and product quality assessment, whilst in the oil and gas sector it is required for allocation in shared transportations systems and for reporting annual production - the flow measurement system is, in effect, the cash register for the production facility.
Depending on the technology used, the flow rate may be measured by mass or by volume but there is often a requirement to convert between these quantities.
This requires a knowledge of the density of the fluid, as a function of temperature and pressure. Density, therefore, becomes a fundamental part of the flow measurement system.
Dr Norman Glen, TUV SUD NEL's density measurement expert, along with Dr Claire Forsyth, will present this popular webinar topic once again which will explore issues associated with on-line density measurement and calculation techniques for liquid density determination.
Join us on Wednesday 8th August, 2pm.

EXPERT PROFILE | Dr Norman Glen
Dr Norman Glen is one of the world's leading experts in fluid properties measurement.
What roles have you played/currently at NEL
I have worked on a wide range of projects including heat exchanger fouling, stack emissions monitoring, the application of data reconciliation techniques to flow measurement in pipe networks and the traceable calibration of industrial densitometers, all of which require traceable measurements. For the past 15 years I have been directly involved with many aspects of the UK National Measurement System (NMS) including formulation and delivery of programmes and projects in support of the NMS, such as the development of the CO2 measurement infrastructure at NEL. I also support many aspects of NEL's knowledge transfer activities, for example through publications, presentations and webinars (I gave NEL's first webinar, on flare gas measurement, in June 2012).
Where were you prior to NEL?
I joined NEL in 1983, after doing a PhD with Glasgow University, supported by NEL, on the measurement and modelling of thermophysical properties of fluids at elevated temperatures and pressures.
What is your academic background?
I have a BSc (2.1) in Chemical Physics (Glasgow University, 1980) and a PhD ("viscosity coefficient measurement at elevated pressure", Glasgow University, 1985).
What are you main area(s) of expertise?
Thermophysical properties of fluids
Heat exchanger fouling
Industrial water use
What are your current key projects and main clients?
I am heavily involved with two current Flow Programme projects, FPDE05 (Flow measurement infrastructure for high pressure injection systems) and FPDE06 (Infrastructure to support the transition to cleaner fuels), both of which make use of my expertise in thermophysical properties of fluids. I am also the technical lead for our Industrial Densitometer Calibration Service, which involves interaction with a wide range of operators and regulators including OGA and NPD.
What excites/interests you about working at NEL?
The range of topics I get involved with, the colleagues I work with and the clients I interact with.
What future trends do you see developing?
The hydrogen economy - hydrogen as an energy vector (use of renewable energy to generate hydrogen, thus providing storage of energy generated from wind, solar tidal). Although there are numerous demonstration schemes already in action, the true impact won't be felt until there is large-scale role-out, but it will affect electricity generation and storage, transportation and industrial and domestic energy consumption very significantly, hence why NEL are becoming involved with hydrogen metrology.
The IoT - although it is already a very widely-used term, the development of small, cheap, inter-connected sensors will transform many data measurement and processing application, including those in the flow metrology area.
