BTU Energy Metering Systems for Accurate Thermal Measurement

SRB Controls offers a full range of BTU energy metering systems designed for reliable thermal-energy measurement in heating and cooling applications. Our lineup includes Measurement Canada–approved meters and BTU flow computers for use with both inline and clamp-on flow technologies. Whether you’re managing a district energy network, a multi-building campus, or a process heat system, SRB delivers high-accuracy instrumentation and expert support to ensure traceable, compliant energy monitoring.

BTU Metering

SRB Controls has BTU energy meters for all pipe sizes. We supply small inline BTU energy meters for apartments and condos as well BTU energy meters that are strapped to the outside of 48-inch pipes.

We partner with trusted manufacturers like GWF and pFlow to provide complete solutions that include flow sensors, temperature probes, and energy calculators, all supported by SRB’s commissioning, calibration, and remote monitoring capabilities via MeterConnex.

Frequently Asked Questions About BTU and Energy Metering

What does a BTU meter measure?

A BTU (British Thermal Unit) meter measures thermal energy transfer by combining flow and temperature data from supply and return lines. It’s used to monitor heating or cooling consumption for billing, verification, or efficiency tracking.

Are SRB’s BTU meters Measurement Canada approved?

Yes. SRB offers Measurement Canada–approved BTU meters and flow computers, ensuring legal traceability for institutional, industrial, and commercial energy billing applications.

What’s the difference between a BTU meter and a BTU flow computer?

A BTU meter includes the flow sensor, temperature probes, and calculator in a single system. A BTU flow computer processes data from external sensors and can manage multiple circuits or integration with existing meters.

Can BTU meters be installed without cutting the pipe?

Yes. Clamp-on ultrasonic systems, such as the pFlow D118, measure energy flow non-invasively — ideal for retrofit or temporary monitoring without interrupting service.

How does SRB integrate BTU meters with remote monitoring?

Through MeterConnex, SRB connects BTU meters and computers into a single platform for centralized data logging, analysis, and reporting. This allows operators to track performance and detect issues in real time.
