Ultrasonic heat meter Landis+Gyr Ultraheat-T330/UH30 DN20 (nar-nar)
The Ultraheat T330 ultrasonic heat meter is designed for residential heat metering. This heat meter has an all-metal measuring block with no moving parts in the measuring channel and is equipped with a special internal DuraSurface™ profile, which makes it insensitive to contamination and ensures trouble-free operation with constant measurement accuracy for many years.
The T330 meter is used in both heating and cooling systems. Water is used as a heat carrier or coolant.
