Assessment of Btu Meters for Hydronic Heating Systems. Topical Report October 1985-January 1986

摘要

A review of contemporary Btu meters that could be used with hydronic heating systems was conducted with the goal of identifying either a system suitable for multi-family dwellings and office complexes or the research issues which need to be addressed to develop such a system. Numerous Btu meters are currently marketed; however, they have not received as wide a distribution and use in the U.S. as they have in Europe where they are used extensively in district heating systems. A reliable, accurate and lowcost Btu metering system is expected to find a ready market in the U.S.; however, the quality and cost of the units available in the U.S. need to be optimized. The report presents a synopsis of the state-of-the-art in Btu meters and their main components like flowmeters, temperature sensors, and Btu calculating units.
