The Dynasonics TFX-5000 ultrasonic clamp-on flow and energy meters (photo) are designed for non-invasive, ultrasonic transit-time measurement for use in water and wastewater treatment, heating, ventilation and air conditioning (HVAC) and oil-and-gas applications. TFX-5000 meters measure volumetric flow and heating or cooling rates in clean liquids, as well as those with small amounts of suspended solids or aeration, such as surface water or raw sewage. By clamping onto the outside of pipes, ultrasonic devices like the TFX-5000 meter do not contact the internal liquid and have inherent advantages, such as reduced installation time and cost. The TFX-5000 devices are available in two versions: a flowmeter for water delivery, raw sewage, cooling water, sea water, deionized water, water-glycol mixtures, alcohols, chemicals and many caustic fluids; and a heating/cooling energy flowmeter used in conjunction with dual clamp-on resistance temperature detectors (RTDs) for temperature measurement in hydronic processes and HVAC systems. — Badger Meter, Inc., Milwaukee, Wis.
