ULTRASONIC FLOW SENSOR APPLICATION Ultrasonic flow sensor QALCOSONIC F2 is designed as sub-assembly of heat meter for measuring heat-conveying liquid volume in heating/cooling systems and conversion it into electrical pulse signal. It is used in conjunction with the type approved heating/cooling energy calculator. As a component of heat energy meter the QALCOSONIC F2 flow sensor could be used for commercial account of energy quantity in district heating plants, in factories, in single or multifamily houses. • Dynamic range up to Qp/Qi = R 100/250 • Temperature of conveying liquid: 5° C ...130° C • Power supply options: Battery/External 24V AC/DC • Battery lifetime > 12 years • Mounting in any installation position • Can be mounted in both flow and return pipe. • No straight sections required up to DN50 • Pulse value is freely ordered1 Ultrasonic technology • High accuracy

POWER SUPPLY: Power supply (one of following depending on meter configuration): • AA battery 3,6 V 2,4 Ah (Li-SOCl2) battery, operation time at least 12 years, • 12..42 V DC or 12...36 V 50/60Hz AC external power supply, used current 10 mA and back up battery AA 3,6 V (Li-SOCl2), operation time at least 12 years.
