DN50-400 ULTRASONIC HEAT METER
The T3-7 series ultrasonic Heat Meter based on GB/T32224-2020They are two-channel and four-channel Ultrasonic Heat Meter with highintegration.
This series of ultrasonic heat meter has many advantages, such as wider measurement range, ultra low power dissipation, stable and reliable performance etc. Every single part of this series ultrasonic heat meter reaches IP68 protection grade, which can be used in all kinds of harsh working environment. They are extensively used in thermal power plants, heat ex-change stations, heating-supply companies, refrigerating systems, central air conditioning and other fields for heat and cooling capacity measurement.
