Energy Management Equipment
Our BTU meter is a new generation ultrasonic heat and cooling meter designed to measure heat and cooling energy consumption. It is used in district heating and cooling applications, such as residential houses, companies, organizations, and heat supply facilities. The precision of measurement helps to reduce energy loss, and the innovative body combined with latest technology and a long-life battery expands the meters capabilities, the precise measurements and detailed data provided by BTU meters help achieve higher energy efficiency and reduced costs of energy.
What is BTU meter?
BTU meters are devices used to measure the energy consumption of cooling and heating in HVAC, ventilation, and air conditioning systems. These meters calculate the amount of thermal energy transferred by tracking the flow rate of a cooling and heat transfer fluid (usually water) and its temperature difference across the system. BTU meters are essential in various applications, including residential, commercial, and industrial settings, to monitor and optimize energy usage, ensure fair billing, and support energy efficiency initiatives. By providing accurate and real-time data on thermal energy consumption, BTU meters help in managing energy resources more effectively and reducing operational costs.
