2 Function and system design Measuring principle Prosonic Flow operates on the principle of transit time difference. An acoustic signal (ultrasonic) is transmitted from one sensor to another. This can be either in the direction of flow or against the direction of flow. The time (transit) that the signal requires to arrive at the receiver is then measured. According to physical principles, the signal sent against the direction of flow requires longer to return than the signal in the direction of flow. The difference in the transit time is directly proportional to the velocity of the flow. Prosonic Flow calculates the flow rate from the pipe cross-sectional area and the measured transit time difference. v t Q = v A V = flow velocity t = transit time difference between the signal in the direction of flow and against the direction of flow Q = volumetric flow A = pipe cross-sectional area In addition to the volume flow, the system measures the sound velocity in the liquid. The sound velocity can be used to distinguish different liquids or as a measure of product quality. You can carry out an application-specific calibration of the Prosonic Flow in the field using the Quick Setup. Measuring system design The Prosonic Flow ultrasonic flow measuring system always consists of a transmitter and the related measuring sensors. All components are available in different versions depending on the application requirements. The transmitter is used to actuate the measuring sensors. The electronics and the software in the transmitter are used to prepare, process and evaluate the sensor signals and to convert the measuring signal to the desired output variables. The measuring sensors work bidirectionally as sound transmitters and sound receivers. The electrical signals of the transmitter are converted to a pressure signal in the measuring sensors and vice versa. Depending on the design, the different sensor versions of the ultrasonic flow measuring devices offer unique possibilities in the application. Properties and benefits of the various versions are explained on the following pages. 2

3 Sensor arrangement The transmitter offers 1 to 4 traverses as standard. Please note that every additional reflection will reduce the signal strength (2 traverses = 1 reflection point, etc.). To maintain the best possible signal quality, the least possible number of traverses should be used. To obtain the best possible signal strength and quality, the following traverse options are recommended. 1 = 1 traverse, 2 = 2 traverses, 4 = 4 traverses Recommendations: Due to their design and properties, the Prosonic Flow sensors are particularly suited to certain nominal ranges and pipe wall thicknesses. For this reason, various sensor types are offered for the Prosonic P for these different applications. Recommendations for sensor installation can be found in the following table. Sensor type Nominal diameter Type of mounting Prosonic Flow P 2 to 2-1/2 (DN 50 to 65) 2 to 4 traverses 3 to 24 (DN 80 to 600) 2 traverses 28 to 160 (DN 650 to 4000) 1 traverse Note: The installation of Clamp On sensors is mainly recommended in the 2 traverse type of installation. This type of installation allows the easiest and most comfortable type of mounting which also means that a system can be mounted even if the pipe can only be accessed from one side. If the pipe nominal diameter is smaller than 2-1/2, the sensor spacing with the W and P sensor can be too small for a 2 traverse installation. In this case, the 4 traverse installation must be used. In all other instances, the 2 traverse is the prefered method. The use of Prosonic P sensors from 4 to160 (DN 100 to 4000) is mainly recommended for pipes with a wall thickness > 0.16 (4 mm), pipes made of composites such as GRP, pipes with lining, even for nominal diameters < 4 (DN 100). This also applies to applications with media that has high acoustic damping. For these applications, we recommend mounting the P sensors with 1 traverse. If the measuring device displays an insufficient signal strength, reduce the number of traverses. Sensor selection and signal strength During start-up, the Prosonic Flow 93 automatically adjusts the operating frequency to the pipe and the sensors used. This function ensures that the system always operates at the highest signal strength. As standard, we offer a sensor type for the nominal diameter range of 2 up to 12 (DN 50 to 300) and a sensor type for nominal diameters of 4 up to 160 (DN 100 to 4000). Both sensor types can be used in the 4 to 12 (DN 100 to 300) range. Sensors for the 2 up to 12 (DN 50 to 300) should be used for wall thicknesses < 0.16 (4 mm). Sensors for 4 up to 160 (DN 100 to 4000) should be used for pipe wall thicknesses > 0.16 (4 mm). 3

4 Two-channel measuring devices PROline Prosonic Flow 90/93 has two measuring channels which are independent of one another. In other words, the transmitter supports the simultaneous operation of two sensor pairs at two individual measuring channels. In doing so, the resources of the transmitter are split evenly between the two channels. This allows the transmitter to be used in different ways: Two-channel measurement Two-path measurement The transmitter can output the measured values of both channels either individually or arithmetically linked (as total, difference or mean). Two-channel measurement In the case of dual-channel measurement, the measured values of two independent measuring points are determined and processed by one transmitter. a b a Power supply cable b Signal cable (outputs) If required, the measured values of measuring channel 1 and measuring channel 2 can be arithmetically linked together. The following possibilities for outputting measured values are suitable for dual-channel measurement: Individual output of measured values from channel 1 and 2 Total of measured values from channel 1 and 2 Difference of measured values from channel 1 and 2 The measuring device supports the individual configuration of the measuring channels and the independent setting of the display and outputs. As a result, the sensor type and type of installation, for example, can be selected and configured separately for both channels. Note: Please pay special attention to the installation recommendations in Mounting location, Page 14; Orientation, page 16; Inlet and outlet runs, Page 17 as well as the recommendations on the type of installation, Sensor arrangement, Page 3. 4

5 Dual-path measurement In dual-path measurement, the transmitter is used to operate two sensor pairs (4 sensors) which are installed on the same pipe. Different applications can necessitate different types of installation. A B a b a b a Power supply cable b Signal cable (outputs) Note: Please note the recommendations in Sensor arrangement, Page 3. The following possibilities for outputting measured values are suitable for dual-path measurement: Individual output of measured values from channel 1 and 2 Arithmetic mean of the measured values from channel 1 and 2 (CH 1 + CH 2 / 2) The possibility of obtaining the mean value in dual-path measurement provides the advantage of a more stable measured value. A measured value that is generated from two independent measuring signals is generally less sensitive to irregularities and faults in the application. As a result, if conditions are not ideal, for example, the dual-path system means that the different flow components within the flow can be better determined thanks to the fact that the measured values are determined independently on two levels. Differences are than balanced out when the two measured values are subsequently averaged to form one process variable. This often results in a more stable and more accurate measured value than would be in the case with single-path measurement. The measuring device supports the individual configuration of the measuring channels. Note: Please pay special attention to the installation recommendations in Mounting location, Page 14; Orientation, Page 16; Inlet and outlet runs, Page 17; as well as the recommendations on the type of installation in Sensor arrangement, Page 3. 5

15 Operating conditions (installation) Installation recommendations Mounting location Correct measuring is possible only if the pipe is full. Avoid the following locations: Highest point of a pipeline (risk of air accumulation) Directly upstream of an open pipe outlet in a vertical pipe Vertical pipe mounting Correct installation in a vertical pipeline is possible using the recommendations in the figure. Restrictions in the piping or an orifice with a smaller cross section than the nominal pipe diameter can prevent the pipe from running empty while the measurement is in progress Recommended vertical pipe installation 1 Supply tank 2 Measuring sensors 3 Orifice plate or pipe restriction 4 Valve 5 Filling tank 15

16 Installation orientation Vertical (View A) The recommended flow direction in a vertical pipe is upwards. Entrained solids sink downwards and gases rise away from the measuring section. This also allows the pipe to completely drain during no-flow conditions and protects the pipe from solids accumulation. Horizontal (View B) The recommended horizontal installation orientation is shown below. This ensures that gases in the upper portion or solids in the lower portion have minimal effect on the measurement. The recommended installation range for maximum sensor performance is 120 (gray area C). A C C B Mounitng orientation A Vertical, flow upwards B Horizontal C 120 installation range Acoustic coupling medium A coupling medium is required in order to ensure good acoustic contact between the sensor and piping. This is applied to the sensor during installation and does not normally require replacement. The Prosonic Flow 93 includes a coupling monitoring function as part of the Extended Diagnostics software package which outputs the signal strength as a limit value. 16

17 Inlet and outlet runs To ensure a fully developed flow profile, the sensors should be installed upstream from flow obstacles such as bends, reducers, or valves. The accuracy of measurement can be affected if these values are lower than those given. If there are several obstacles in the flow, then the longest inlet or outlet path must always be used. ³ 15 x D ³ 5 x D D = Nominal pipe diameter ³ 40 x D Valve ³ 20 x D Pump ³ 40 x D Two elbows in different planes Connecting cable In order to ensure measuring accuracy, route sensor cables well clear of electrical machinery and switchgear.
