Abstract
Flow metering is absolutely required for evaluation of energy usage. In fact, determining usages and heat balances without metering are simply educated guesses. Recent technological innovations in flow metering have produced clamp-on, portable flow meters to measure liquids.
This paper reviews the principles of ultrasonic flow meters. Applications and costs of ultrasonic versus orifice flow meters are important to consider in energy audits. A discussion follows on 'how' and 'where' to use ultrasonic flowmeters. Estimated costs contained in this paper encompass equipment costs as well as installation costs associated with both ultrasonic and orifice meters.
