How does it work?
Our Portable Ultrasonic flow meters are cross-correlation transit time Portable Ultrasonic flow meters designed to work with clamp-on transducers, to provide accurate measurement of liquid flowing within a closed pipe, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install and there is no need to shut down flow or drain the system!
When ultrasound is transmitted between the transducers, its velocity is slightly increased when traveling in the direction of flow, and slightly reduced when traveling against the flow. The resulting transit time difference is directly proportional to the velocity of the flow in the pipe. Having measured the flow velocity and knowing the pipe cross-sectional area, the volumetric flow can be easily calculated.
Features & Benefits
Our Portable flow meters are simple to install and configure, no specialist skills or trades are required. They just clamp onto the outside of the pipe and are non-invasive, so no need to drain down systems, cut pipes and install flanges. As a consequence, the install time and associated disruption and cost are very small in comparison to traditional in-line meters. Other benefits of being non-invasive are that there is no pressure loss in the system and there is no risk of contamination of the fluid.
The significant features and associated benefits make our Portable Ultrasonic flow meters particularly suitable for liquid flow and hydronic energy investigations in HVAC/Building Services applications for example in Data Centres, Airports, and Hospitals where minimal downtime and maximum availability of metering systems are essential to ensure continuity of operation. And in Process or water industry applications, the non-invasive feature and associated benefits minimise production disruption and maximise availability to avoid costly shutdowns due to system pressure drop or contamination for example in the measurement of flow within systems associated with the production of semiconductors or food processes.
