An ultrasonic BTU meter uses ultrasonic flow measurement and temperature sensors to measure energy consumption in liquid heating and cooling systems. It can output measurements in British Thermal Units, Kilo Calories, or kilowatts. Ultrasonic BTU meters are available in sizes from 50 to 1500 mm and can have clamp-on or insertion installation. They measure flow and temperature accurately with no moving parts and provide isolated analog and digital outputs. Common applications include chilled water billing and leak detection in hot or cold water pipes.

Introduction
• 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.
• It can give outputs in British Thermal Units(BTU), Kilo Calories(Kcal) or in KW
• Available communication ports are BACnet, MODBUS with LAN Port.
• These meters can be either Clamp-on type or insertion type.
