Measure the diameter of the pipe. For example, assume the pipe has a diameter of four feet. Video of the Day Step 2 Determine how accurate your measurement needs to be. If you need a general estimate, you can use 3.14 as pi. If you need more accurate measurements, you should carry pi...
More accurate gauges typically have a bigger diameter. Pressure connectors are normally parallel pipe threads (G) according to ISO 228-1, or taper pipe threads (NPT) according to ANSI/ASME B1.20.1. There are also digital pressure gauges that have a numeric pressure indication instead of an ...
Step 1 Measure the diameter of the pipe. For example, assume the pipe has a diameter of four feet. Step 2 Determine how accurate your measurement needs to be. If you need a general estimate, you can use 3.14 as pi. If you need more accurate measurements, you should carry pi out to ...
I don't have any way to measure across the whole range accurately, but this gives you an idea. The controller board outputs a 9.5 VDC pulse to the solenoid. The solenoid draws about 0.3 Amp. The controller uses a TIP122 transistor (with no heatsink) so you should be able to load it...
parallel Metric threads is that an O.D measurement will reveal the actual thread size (i.e. 18.01mm measurement means the thread is likely M18). However, to do this accurately with Tapered Metric threads one must measure the O.D at the third row of threads from the end of the fitting....
NPT Pipe, Thread and Tube Sizes NPT thread and nominal pipe sizes © Eugene Brennan Pipe Sizes and Standards Can Be Somewhat Confusing For example, if you measure a 1/2 inch pipe or 1/2 inch fitting, neither the internal or external diameter of the pipe nor the diameter of the thread...
• Since flammable vapors are usually heavier than air, it is important to draw from the bottom vent and provide fresh air from the top vent. Seismic Protection For earthquake or hurricane-prone regions, or simply where an added measure of stability...
DO NOT adjust or attempt to measure gas valve outlet pressure. The gas valve is factory-set for the correct outlet pressure. This setting is suitable for natural gas and propane, requiring no field adjustment. Attempting to alter or measure the gas valve outlet pressure could result in damage...

to measure the the variation as the muscle contracted. Despite the silicone tubing (but probably because of my translucent fitting) I had lots of interference from ambient light. The readings were all over the place. I suspect that this was due to misalignment of the LED and photo-transistor...
