BTU Meter

What is the BTU Meter ?

What is it?

BTU (British Thermal Unit) meters are devices used to measure the heat energy flow in heating, ventilation, and air conditioning (HVAC) systems. They can be used to accurately monitor energy usage, identify inefficiencies, and optimize system performance.

Why we use it?

We use BTU meters to improve energy efficiency, reduce operating costs, and ensure accurate billing for heating or cooling services in commercial and industrial buildings.

How it works?

A BTU meter typically contains sensors that measure the temperature differential and flow rate of a liquid or gas passing through a pipe. Based on these measurements, the device calculates the amount of heat energy being transferred and reports this data to a building automation system or controller.

Major brands that manufacture it

Some of the major brands that manufacture BTU meters include Siemens, Kamstrup, Itron, and Elster.


There are different types of BTU meters, including inline and clamp-on models, with various measurement ranges and communication protocols to fit different applications.

How do we select it?

When selecting a BTU meter, consider factors such as measurement range, accuracy, communication protocols, compatibility with your existing control and automation systems, and compliance with relevant industry standards.

How to install it?

BTU meters should be installed according to the manufacturer's recommendations. Sensors should be securely mounted on pipes and any necessary wiring connections should be made to the building automation system or controller.

Wire connections required to receive the signals

The wire connections required to receive signals from a BTU meter may vary depending on the specific device and building automation system. Typically, they will require electrical wires that connect to the building automation system or controller. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
