An Ultrasonic BTU Meter for HVAC systems
BTU meter measures the thermal energy content of liquid flow in British Thermal Units (BTU) or in Kilo Calories (Kcal)., even sometimes in Kw.
Manas makes Ultrasonic BTU meters that can provide a solution for calculating the BTU or measuring the BTU consumption with their BTU meters with communication support like BACnet, MODBUS with LAN Port.
An Ultrasonic BTU meter comprises a combination of an ultrasonic flow meter with temperature sensors that measure energy consumption in any liquid heating or cooling system.
The ultrasonic flow meter can be either Clamp-on type or insertion type.
The Ultrasonic BTU meter gives long life, is trustworthy, and provides good accuracy.
Features
- Size available DN50 – DN 1500
- No moving parts and fast response to flow transits
- Highly accurate and reliable
- Isolated 4-20 mA output proportional to flow rate
- No need to cut the pipe or stop water, easy installation for clamp-on type
Applications
- Used for measurement for energy consumed
- Measures thermal energy required for air conditioning system
- Used in chiller water application with temperature sensor
Benefits
- Can provide precise readings even at low flow rates, making them suitable for a wide range of applications.
- They have no moving parts, which reduces the need for regular maintenance and minimizes the risk of wear and tear over time
- Due to their design with no moving parts and robust construction, ultrasonic BTU meters tend to have a long operational lifespan.
- Non-invasive flow measurement with clamp-on sensors ensures no contamination of the process medium

FAQ's
It uses ultrasonic sensors to measure the velocity of the fluid and the temperature difference across the system. With this information, it calculates the BTUs exchanged.
They are used in various applications, including district heating and cooling systems, HVAC systems in buildings, industrial processes, and renewable energy systems.
