The Prosonic Flow B 200 offers full bore design; robust, dual-compartment housing; and diagnostic capability for process transparency. The B 200 also offers a specialized sensor design optimized for low pressure gas. The meter features a separate connection compartment for convenient device wiring. In addition to efficient process control and energy balancing, Heartbeat Technology ensures compliance and process safety at all times. The display features touch control and background lighting, eliminating the need to open the device.

The E+H Proline Prosonic Flow P 500 Clamp-On Ultrasonic Flow Meter applies a non-invasive measuring principle independent of pressure, density, and conductivity. The meter provides a bidirectional measurement of various fluids, e.g. liquid hydrocarbons and chemicals. The built-in FlowDC (Flow Disturbance Compensation) maintains accuracy even when the meter is mounted with a short inlet run. A stable signal is accomplished via maintenance-free permanent mounting from outside with coupling pads. Sensors for GRP and plastic pipes are available. The freely combinable I/Os offer full access to process and diagnostic information, as well as variety and reduced complexity. 

The measuring system uses a measurement method based on the transit time difference. In this measurement method, acoustic signals (ultrasonic) are transmitted between two sensors. Signal transmission is bidirectional, i.e. the sensor operates as both a sound transmitter and a sound receiver.

As the speed of propagation of the sound waves is slower against the flow direction than in the flow direction, this results in a transit time difference. This transit time difference is directly proportional to the flow velocity.

The measuring system calculates the volume flow of the medium from the measured transit time difference and the pipe cross-sectional area. The sound velocity of the medium is simultaneously measured along with the transit time difference. With this additional measured variable, it is possible to differentiate between different media or monitor the medium quality.
