Flo-Sonic FPFM

The Flo-Sonic FPFM is a permanent measurement system for full pipe applications using the ultrasonic transit time technology. It is designed to suit a large range of applications for clean to polluted water with pipe diameters ranging from 50 to 3000 mm. The Flo-Sonic FPFM can be equipped with either clamp-on sensors or insertion sensors.

The Flo-Sonic FPFM system consists of one ultrasonic speed processor and monitor and two Flo-Sonic probes per path. The Flo-Sonic FPFM can be equipped with up to 2 measurement paths and used as a dual flow meter measuring the flow on 2 different pipes controlled by the same processor and monitor.

Very complex applications can be equipped with up to 16 measurement paths. The Flo-Sonic OCFM uses the very latest electronic technology combined with highly efficient digital signal processing (D.S.P.). The D.S.P. technique maximizes the system performance giving the user significant benefits.

Operation principle:

The Flo-Sonic measurement principle is based on detecting the transit time of ultrasonic signal between two sensors. The transit time with flow is shorter than the transit time against flow direction. The difference between these transit times is proportional the average flow velocity along the measurement path.

Key Features:

  • Non-invasive external probes clamped on the pipe
