I did a search and did not find a recent discussion on flow thru versus non-flow thru TPMS. I didn't look real hard so sorry if this has been discussed or is so obvious it doesn't warrent discusing.
Currently I have a two axel TT pulled by SRW pick-up.
Any pros or cons for either sensor?

Oh, and while we're on the subject, what about replacable batteries versus non-replacable?
Dutch said

I prefer the lighter weight and less bulky non-flow thru sensors. On our TST 507 system, I've removed the rotating security covers, making the sensors even lighter and less noticeable. That also makes removing the sensors to air up no different than removing regular valve caps. As for the battery question, I originally had a TST 510 non-user replaceable battery system. When the batteries started to fail after 5-6 years of full time use, it would have cost about $200 to replace the ten sensors with fresh ones. By switching to the TST 507 user replaceable battery system, the batteries need replacing every year or so, a simple process, and they cost less than $1 each. That makes my 5 year cost less than $50, versus the $200 sensor replacement cost for the 510 sensors.

One other thing to consider is the orientation of the valve stems, the size of the holes in the rim if you need to get fingers inside to install/remove the sensors (you do on my 5500) and the size of the sensors…need to make sure you don't paint yourself into a corner.
I have the non-replaceable sensors on my PressurePro…upgrading to the newer sensor type would force me to upgrade the whole system which sort of skews the 5 year cost.
Mine are non flow through…but PressurePro does sell some little add on doodads that screw onto the stem with a flexible steel hose leading out to 2 stem connectors…one for the sensor and one for air…and a bracket that goes under a lug bolt to hold the sensor/inflation end. I didn't get them because the $120 or so cost for the 4 I need was too much to pay for the slight bit of aggravation having them saves. The only sensors I have issues with are the inside dualley ones…but now that I know the right position to get the wheel in and where to stick my hand in it's only about an extra 3-4 minutes per side to get them on/off.
One issue with the flow through ones is that the set point doesn't reset itself unless you take the sensor off for 60 seconds…so depending on your whether this needs to get reset then maybe you have to take the sensors off anyway. I've found that I have to generally change tire pressures once in the spring as we head north and again in the fall as we head south. That doesn't necessarily change the set point but if you're close to an alarm and happen to put 2-3 psi more in a tire today then you can get erroneous high pressure alarms…ask me how I know this as Bill is want to say

Thanks Dutch. It’s good to hear that the sensors actually lasted five -six years. Is that common? Those sensors live in a pretty harsh environment.

My application is rather simple so I’m leaning to the non-flo thru also. When I graduate to a big-boy RV and truck in about four years, I my rethink the TPMS.

From other reports I've read, 5-6 years of battery life for the 510 sensors seems to be fairly typical. The battery life can be extended somewhat by removing the sensors between trips.

When my TST 510 sensors needed replacing, TST offered me deal on the user replaceable battery 507 system that came to only about $50 over the sensor replacement cost alone. Close enough that I couldn't refuse anyway...

I called TST at the time, and spoke with Dan Covington. He is very helpful on all things TST...

Hi,
I think the important thing on this the accuracy, reliability and easy-to-inflate. I have used one of external mounted sensor, named as FOBO. The best part of this is you can get your reading straight to your smartphone. It uses Bluetooth LE so I think it's a really good thing to have one if you're concern about tire pressure (it measure battery and temperature too)
The battery is replaceable, so it is convenient that we can just do it by ourselves.

Speaking from experience I can say that that is true. I currently have both ... flow thru on the 5th wheel and non flow thru on the truck (due to size and available space to install). Having had both, I would follow Dutch's plan. Buy the non flow thru and remove the outer cover as he has done. Replaceable batteries last about a year or so and cost about a dollar or so to replace. Dutch has a good plan.

My PressurePro sensor batteries lasted about 4 years before they started losing the signal to the cab unit.

So to recap the answer to the OP was??? Non-Flow Thru Sensors? Good feedback! Any concerns about the constant pressure on the shutoff insert in the valve stem with the screw on sensors? Any leaks or issues with that aspect of the sensor system?
Dutch said
06:00 PM Jun 10, 2017
I've been using TST sensors since 2008 with no leaks to date. I do pay close attention to the condition of the seals when removing and reinstalling the sensors.
