MONITORING & METERING
modified 747 jet engine running on gas. These sites can be started and shutdown very quickly, usually within
15-20minutes.Thisiscomparedtoacoal fired power station which requires about four weeks and nuclear power station fourmonths. These are especially useful on days when wind and solar are not able to output enough to meet demand.
7. Key points in the distribution network,this helps to manage the system but can also be used to detect leaks or theft.

4. Truck and Ship loading/
unloading.Ships are often used tomove product from one country to another. Trucks can be used to deliver product to off-grid locations, and this is especially true for refined products like petrol or diesel.
5. Factories and industrial
processes.Veryhigh energy demand processes – such as steel and cement works, and brick kilns – are required by EU legislation to have accurate measurements of usage, which can also be used to calculate emissions, (see point 10). The flow of coolant systems that are critical to the safety of such processes can bemonitored using flow computers.
6. Standby electricity generation
stations.These are placed at strategic locations, ready to deliver electricity at short notice by using, for example, a
8. Biogas injection sites. Waste organic matter is ‘brewed’ to release methane which is mixed with propane to increase the calorific value above the minimum level before injecting into the national grid.
9. Hydrogen generation. Mostly standalone but could be usedmuch like a Biogas Injection site, or in a closed system, to store wind and solar energy.
10. Exhaust emissions and efficiency measurements using standards such as BS8609:2014. By accurately measuring what fuel goes in and energy/work produced, a measure of efficiency can be made which can be used to predict maintenance requirements and pollution released from the process.
11. Steam, as a byproduct of electricity generation and other processes, can be sold to other nearby factories as a means of saving energy used for heating water. Steam is used during

steel production for both heating and cooling, as well as mechanical power.
CALCULATING FLOW Although primarily targeted at the hydrocarbon gas and oil market, the SFC3000 Flow Computer can be used to calculate flow ofmany other gases and
liquids including hydrogen, water, steamand CO2. Both of the terms ‘measure’ and ‘calculate’
have been used in this article. For clarity, the flow computer can make measurements directly or can accept values measured by other equipment to perform calculations to produce values that can represent an amount of product. This amount can be expressed as flow with time or a total in terms of volume, energy contained in the product or mass of product. These results can be displayed on the flow computer and/or transmitted to other systems for use. In summary, if it flows in a pipe, Ex-i can
measure it. The company understands the long term stability, reliability and accuracy required by the measurement industry and has therefore produced a flow computer that meets or even exceeds these expectations.
