3/8" BSPP Female to 1/4" NPT Male

[MrToad]

Does such an adaptor exist in the UK? I mean, as stock product, not as "order 10k units minimum".

I don't mind if it's made of SS-316, Brass, Kevlar, Kylar, Nylon or Microwave Hardened African Elephant Crap.

I haven't been very successful "googleing" for it so far

What do you need the fitting adapter for?

[MrToad]

Connect a SF800 flowmeter to a filter. The SF is 3/8" BSPP Male and the filter is 1/4" NPT Female.

I'd rather not having to put barbs on each, although if that kind of adapter doesn't exist I'll have no other choice.

How about one of these 3/8 BSP to 1/4 NPT M/M:

Then you have a number of options. i.e. 3/8 BSP Female to Female Coupler, Ball Valve or T.

The base of the T could then be fitted with a plug or a drain.

You shouldn't leave a filter in place permanently as it is a flow killer. You should only leave it in for a week or two then take it out of the loop.

Is a double flow killer. The filter kills about 0.4 bar (expected) + another 0.4 bar from the flow meter (that's if I actually achieve the 6-7 lpm I'm hoping for). The filter is in place basically to protect the meter. All my components are brand new, and although I've cleaned them thoroughly, you never know when the radiator is going to release that particle that's gonna screw up your meter.

Unfortunately I won't know the actual flow until I measure it... It's a catch 22 situation

Thank you for the suggestion. It actually makes sense to put a drain ^^. It will help with the mess when, finished the experiments, the flowmeter has to come off

what did the flowmeter cost you? how are you converting the flow to some form of reading?

(i'm looking to connect some type of flow meter into a motherboard connection if possible).

The flowmeter was €37.50. If you live in the US it might be slightly more due to delivery charges.

Well, you can connect it to a MB header. It comes with bare wire, but if you don't have a crimp tool and the pins/housing for the molex 3 pin fan connector, you can always do it the easy way, get a fan extension lead, cut the male, solder the resistors directly in the wire, use some heatshrink tube to cover it and problem solved.

For the reading part you can either use MBM, which let's you change the output parameters, or use the calculator ^^.

The meter sends 6100 pulses per liter. Usually when it comes to rpm, 2 pulses = 1 rev. So 3050 rpm reading = 1 liter per minute.

Divide your reading by 3050 and you're good to go.

If you live in the US, 1 Gallon = 3.785 liters. So to be above the 1 Gpm, you need to read 11545 rpm +. To be in that magic 2.4 Gpm, 27706 rpm.
