BTU meters measure energy change in liquid or gas flows. One BTU is the amount of thermal energy necessary to raise the temperature of one pound of pure liquid water by one degree Fahrenheit at the temperature at which water has its greatest density (39 degrees Fahrenheit). This is equivalent to approximately 1055 joule (or 1055 watt- seconds). Natural gas BTU represents the amount of energy generated by burning one volume of natural gas. A BTU meter is a portable meter. On supplying power to the BTU meter, alphanumeric characters in two separate lines are displayed on the screen. Next, consecutively press and release the supply and return temperature buttons to display the temperature variation in the form of cycle. After successfully displaying the temperature lines, verify them for their correctness. There are many types of BTU meters. Examples include a furnace and energy meter. A BTU furnace is used for raising the temperature of one pound of water by a single degree Fahrenheit. An energy meter is a three phase meter for measuring, recording, and displaying energy consumption. Other BTU meters are commonly available.

There are several ways in which BTU meters function. BTU meters work in bi-directional dual mode. The recorded reading is calculated using a BTU calculator and is displayed on a control system. An operating temperature of BTU meters ranges from 40 to 120° Fahrenheit. The input power required for working a BTU meter is 24 +/- volts, having a frequency of 50/60 Hz, and electric current of 500 mA. In addition, an 18 to 22 ga shielded cable is recommended for flow signals. BTU meters are designed and manufactured to meet most industry specifications.

BTU meters are used in many applications. BTU meters are widely used in the automotive industry, power industry, and electrical labs in institutions. BTU meters are designed for use in industries that are free of corrosive fumes and liquid, extreme temperature variations, and heavy condensation. BTU meters are also suitable for environments that have direct liquid exposure. BTU meters should adhere to the standards used in manufacturing ONICON BTU meters.
