Pressure Measurement
 

Here is where we discuss Pressure Measurement.

Pressure can be measured along with Flow (discussed here) either for finding out a block's flow characteristics, or perhaps while measuring the performance.

Suggestions and/or methods to take pressure measurments maybe? This is one area I have zero experience with.

I grazed over it in the Flow Measurement thread.

One option is to go digital. As I painfully discovered the limits of my flowmeter here, I also came up with a way to digitally measure pressure. Relatively cheap, but I never pursued it very far, other than the possibility, and I didn't delve into the accuracy, repeatability, nor calibration.

Otherwise, the simplest way is to use a manometer, as I've suggested many times before, for heatercores:
