BFU-300-F-E Portable Ultrasonic Heat Energy Meter for Chilled and Hot Water
The BFU-300 is an advanced "transfer time" ultrasonic flow meter. This portable model has clamp-on flow trans ducers, meaning that pipe cutting is not required, just clamp on to the outside of the pipe for liquid flow measurement, with the option of heat energy metering with the addition of our PT1000 sensors. BFU-300 clamp-on technology allows the user to quickly verify liquid flow rates or to data log flow system values over an extended time period. The meter can be easily moved around site and is convenient to carry in the protective carry-case suppled. Its portability makes it an excellent choice for measuring flows across sites to verify pump, valve and system performance.

≈ Integral Data logger (32G Micro SD card included)
≈ Analog output 4~20mA
Clamp on ultrasonic flow meters are ideal for applications when system shut down is not feasible, they are non-intrusive and simply clamp on to the outside of the pipe and do not make contact with the internal fluid. Our ultrasonic flow meters are available for a wide variety of pipe materials in sizes from 15mm up to 1200mm.
Transit time or Time of Flight flow meters utilize two transducers which function as both ultrasonic transmitters and receivers. The flow meters operate by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers. The burst is first transmitted in the direction of fluid flow and then against fluid flow. Since sound energy in a moving liquid is carried faster when it travels in the direction of fluid flow (downstream) than it does when it travels against fluid flow (upstream), a differential in the times of flight will occur.
