what is the diffrence between mmwc and kg/cm2 for pressure
measurment when we are using mmwc and when kg/cm2 and why?????
?? what is the reason
Answer Posted / manimaran
when we r measuring very low pressure :: mmWC and general terms is Draft pressure and measuring high pr. :: kg/cm2/bar/psi...for example we r measuring like boiler furnaces pressure and flue gas path (draft) i.e very low pr.(250mmWC) so we r measuring in mmWC, and when we are calibrating the flow, draft and level transmitters we will indicate the range in mmWC. The error value for FSD will be higher side for the transmitters which are calibrated in mmWC.
