True Blue Ultrasonic Heat Meterzelsius ® WR3-IUF - Heat Exchanger Station Use
Utilizing ultrasonic measurement technology, we offer solutions for metering large heating/cooling pipelines, particularly suitable for heat/cooling metering in buildings, heat exchange stations, or district heating stations.
Zelsius® WR3-IUF features a wide measurement range for large diameter heat meters, with a housing made of high-grade stainless steel castings. It maintains stable measurement under low flow and polluted water conditions. The metering mechanism, optimized for fluid dynamics, ensures the WR3-IUF's durability in cold/hot measurement and ease of installation. It is also equipped with IP68 protection to ensure the meter's installation in harsh environments.
The Zelsius® WR3-IUF accumulator for large diameter heat meters can be independently separated and installed in a suitable location, saving installation space on-site and facilitating the reading of various data. The accumulator also displays the meter's operating status directly through a large LCD screen. With a single button, you can conveniently operate and read consumption data, such as the daily usage on the day of reading, historical usage values, or the monthly historical data stored during the entire usage period of the meter.
