hi,
does any experience this problem before :
On the BMS/BAS monitor screen, the chiller tonnage is X ton. but when i used the formulea
ton= (16*flow(l/s)*Delta T)/24, the value is often different ?
This is due to equipment calibration out. I yet to ask my BMS guy wat wrong ?
Is there a...

Will do a search on the internet too.
