DN25 Ultrasonic Heat Meters with M-Bus

DN25 Ultrasonic Heat Meters with M-Bus are kinds of home end used ultrasonic heat meters and there are ultrasonic Heat Meters DN15,DN20,DN25,DN32 and DN40 . Comparing with the mechanical heat meters, the DN25 ultrasonic heat meters with M-Bus have outstanding advantages:  The total absense of moving parts ensures maximum measurement accuracy,maintenance free performances and consistency of operations over time. The fluids volume measurement with the ultrasonic technology does not get affected by the presence of debris and deposits in the heating liquid and allows the mounting of the M-Bus ultrasonic heat meter DN25 in both horizontal and vertical with upward or downward flow direction.
