Portable ultrasonic flow meter P401 Energy

The P401i is a compact and mobile clamp-on ultrasonic flowmeter for non-invasive measurements on filled pipes. The device is primarily designed for temporary measurements. However, thanks to the integrated data memory and a battery life of up to ten hours, the device is also suitable for longer periods of use.
Energy measurement is also possible with this device thanks to high-temperature sensors. By using a connection box, the signal outputs in analog and digital versions as well as the Modbus RTU interface of a permanently installed device can be implemented on this mobile version.

The ultrasonic flowmeter uses the transit time difference method to determine the determination of the flow velocity or flow rate. The sensors of the ultrasonic flowmeter serve both as transmitters and receivers. as well as receivers. The ultrasonic signal through the pipe through which the medium is flowing pipe through which the medium flows has different transit times or transmission times depending on the direction. The ultrasonic waves of the signal propagate faster in the direction of flow than against the direction of flow. Due to these different signal propagation times time difference which is proportional to the flow velocity of the fluid. of the fluid.
