Even when properly applied, it seems the terrorists may just need two vehicles. One to displace the barrier, and one to do the deed. That means the lone wolf may need a partner, which probably decreases the odds a plan comes to fruition, which is good, but it's not total prevention.
Who cares, right? Once you get your system built with the transducers in place, get the system data and develop your flow correlation. Then, the details and intricacies of your system are baked into the data and your flow correlation.
The best way, of course, is to get real flow data on your installation (coil, pipe, and fittings - entire system). Then, provide a calculation methodology or a Look-up table or something.
Crane TP410 has a calculation method for coils too. Coils come in all kinds of shapes and sizes. You'll...
I graduated May 12 and started work May 14. 1979! I worked 45 years, was sold twice, never laid off, and retired this July. I credit my strong work ethic.

Jon,
The title says it all. I can't change my e-mail address. I retired and my old company e-mail address is no longer valid. In Account Details, I click "Change" beside the old e-mail address. I get a text box that asks for my password and I hit "Save", and, then, nothing happens. Help!
1: can you put the thermowell in an elbow and use the inline pipe for the thermowell? Check your standards or Google elbow thermowell standards.
2: do you mean nozzle extension from vessel wall? 8” (200 mm) is very common, but I’ve seen “as short as possible” up to 12”. I’ve never seen 1800 mm.
Back in my old phenolic resin days, after the operator opened the vent and cracked the man way open < 1 inch they would put a slight vacuum drag (negative pressure) on the still before opening the man way wide open. Man ways had cross bars so no one could fall in.
That was 40 years ago...
Addition systems can be engineered and built so the manways can be closed permanently, or until maintenance turnarounds occur. Decades ago, I saw the same thing where I worked. It's a management problem. Management has to decide whether exposing people is okay or not. There will be a lot of...
m/sec is not a variable. It’s the units of mass flow rate (m).
Snickster gave you the definitions. Please read them:
m is mass in pounds (weight mass W not W/g mass)
m/sec is mass flow in pounds per second
MW is the molecular weight of gas which is S.G. times 29 (MW for air)
Z = 1 for NG...
