Page 23: The Flow Sensor
Manufacturers of flow sensors have been working with alternative techniques to replace the mechanical principle. Research and development at Kamstrup have proven that ultrasonic metering is the most viable solution. Combined with microprocessor technology and piezo-ceramics, ultrasonic metering is not only accurate but also reliable. - Page 24 ® TECHNICAL DESCRIPTION MULTICAL In principle flow is obtained by measuring the flow velocity and multiplying it by the area of the measuring pipe: × where: is the flow is the flow velocity is the area of the measuring pipe The area and the length that the signal travels in the sensor are well-know factors.
