Flow sensors and transmitters, flow meters
The flow rate meter type SU is an inline flow rate meter. The propagation time of the sound depends to a large extent on the medium (gaseous, liquid). Therefore information about the type of medium must be given to the measuring system so that the respective correction factors can be included. In addition to simple flow rate monitoring the SU also monitors the temperature of the medium. It is displayed on site and provided for signal processing. This makes the system particularly suitable for the monitoring of cooling circuits, because temperature and flow rate can be monitored at the same time. The processed information for integration into the process and further processing is of course important for the user. The SU provides a variety of possibilities for representing and processing the data. In addition to the display of all settings and process data on site there are also various possibilities of signal processing. If continuous documentation of processes is required the measured values are available via analogue outputs (0...10 V / 4...20 mA). Binary evaluation of measured values is part of the standard. Pulse outputs for counting and totaliser functions are available internally as well as externally. There is also the possibility to allocate an output to the function of a preset counter. In this case a switched signal is provided after a preset flow rate. The operating principle is simil ar to that of an electronic water meter. A compact design which is ready for connection and can be adapted to various process connections enables the SU ultrasonic flow rate meter to be used in a wide range of applications. All functions described here can be set directly on site via alphanumeric menu navigation, but they can also be set before installation.

1. Piezoceramic sound transducer 2. Measuring length 3. Piezoceramic sound transducer Differential tran sit time principle: Sound pulses are alternately emitted and detected in and against the direction of flow
using piezoceramic sound transducers. The flow rate is exactly calculated from the difference of the transit time (in the nanosecond range from 0.5 to 500 ns). Reliably, wear-and maintenance-free.
