Ultrasonic flow meters can measure almost all light homogeneous fluids including water, wastewater (100,000 data points, time stampedīuilt-in battery with external 12v input, 8-36 hours operation Less intrusive not subject to wear - no moving partsĪpplications for Ultrasonic Flow Monitoring Less intrusive little or no pressure drop less need for recalibration Process temperatures from -40Â☌ to 200Â☌Ĭomparison of Ultrasonic vs Other Types of MeterĪble to measure flow in medium and large pipe sizesĬan measure gas, steam & non-conductive liquids.Wide range of pipe materials and sizes: 12.7-7600mm.Easily installed clamp-on sensors with no interruption to flow.The PT878 portable ultrasonic flowmeter was made obsolete by Panametrics in 2018, but it still available for Rental from RS Hydro. We would recommend this flow meter to professionals who want the most from a portable ultrasonic flow meter. This meter has two external inputs which makes it ideal for a heat metering survey. It is suitable for most pipe sizes and materials, both Water/glycol solutions, crude oil, refined Wastewater, cooling and heating water, ultrapure The PT900 utilises a wide selection of transducers which makes it suitable for mostĪpplications, including many fluids, such as potable water, With superior diagnostics, functionality and accuracy this flow meter is regarded as leading edge technology. The Panametrics PT900 is the latest generation of portable ultrasonic clamp on flowmeter from Panametrics, it is designed to withstand rugged use in industrial applications. Panametrics Portable PT900 Ultrasonic Flow Meter Doppler ultrasonic flow meters are regarded as an old technology offering much poorer accuracies than transit time flow meters. Doppler flow meters using acoustic attenuation caused by the reflection of ultrasound signals from particles or gas bubbles within the liquid. The differential transit time of the synchronised signals is proportional to the flow rate of the fluid. The principle behind this type of non-intrusive clamp-on (strap on) flow meter is that acoustic waves with a frequency of >20kHz are emitted from one transducer to the other side of the pipe back to the opposite transducer requires less time than when travelling in the opposite direction. ![]() Transit time flow meters, or also known as 'time of flight' flow meters are mainly consigned to the measurement of clean liquids, although many flow measurement devices have a maximum tolerance of 5% solids.
