British ThermalUnit Energy Meters, or BTU meters, measure the energy used or transferred in a liquid system. These meters provide accurate data required to effectively track energy usage and allocate cost to tenants. Applications for this meter include heating systems, cooling systems, and heating/cooling systems within both small and large complexes. Submeter Solutions offer a variety of different BTU meter models that can monitor either heating or cooling on the same pipe or both in the same meter. These meters can be connected to an online reading system with the ability to access the meter data remotely.
