Flow meter?

[powerjunx]

How factored and unfactored scale affects flow rate? Flow meter specifies 2ms for unfactored, does it mean that it coincides with the rated flow rate?

Thanks.

Factored? Does that mean compensated or adjusted for pressure and temperature?

One possible explanation for "factored" pertains to the 0-10 square root charts and scales from the panel instrument days. You did not necessarily buy engineering unit scales in those days. Instead the scale read 0-10 with a scale multiplier based upon the engineering units. This would have no relationship to 2 milli seconds.

I love looking up all the old paperwork for the flow meters. You go back into a plant and they have changed the process over the last 30 years and the 0 to 10 root meter is ther and the plant says that meter doesn't match the tank strappings and it must be broken. Plug in new densities and stuff, give them a new scale factor and bingo the meter works now (I've even pretended to fiddle with the transmitter to make it work).

Thanks, guy.

I'm hesistant and getting lose to think the relationship of unfactored scale of having a 2 msec pulse with the flow rate.

Some rather say that this unfactored pulse, or factored pulse relates to flow rate resolution?
