G10 Meter

[Kewat66]

Connecting onto a G10 meter with 22mm replacing a combi boiler with a water heater in 15mm. I don't have commercial but the installation size is within domestic limits. Can I install this? Do I test the meter as normal (the regulator has 2 test points?)

 

[newcastle phill]

Well if its within up/1b...yes ?

Do mean ECV and MIV

 

[Kewat66]

Yes that's correct

Meter volume 0.01m3 + installation pipe volume. UP/1/B test should suffice.

G10 meter volume 0.025m3 ??? + pipework +fittings
test from miv

A G10 is a U16 it should tell you the Qmax (16m²) on the front of it

Hi tamz.
Dont think that points in question.
I was rhetorically stating IV of g10 as reg mans .01 volume incorrect (according to viper)

 

[Dotty]

The IV of a G10 (U16 - as Tamz says, they're the same thing) is 0.025m3 (as Phill says) which leaves the op 0.01m3 to play with.....

Just testing if you were paying attention oop's.

I don't do a TT, am I a bad person?

 

[Reg Man]

Test volume still going to be a domestic TT.

I used to wonder why they called a U16 a G10 or a U25 a G16, U40 - G25, U65 a G40 or even a U6 a G4 etc always stepping down a size from what we were used to.
I asked a guy years ago and the G is related to the Q min eg G10 = 0.1m³ G16 = 0.16m³, G25 =0.25m³ etc.
So now you know.
Btw R5 isn't a meter size on imperials. It can be on any size meter and R5 only means it is pulse enabled. The meter size is on it in cubic feet
.
Full of usless information ain't i :smile:
