Cost-optimized modular design allows application-specific adaptations
The flowmeters of the SQ-FM2PA61 series use the ultrasonic Time-of-Flight (ToF) process. SonoQ piezoelectric transducers have been optimized for this application for the generation and reception of sound waves. In the flow direction, the flow velocity is added to the sound velocity or subtracted in the opposite direction. The difference in the sound propagation times is proportional to the flow. On the basis of the measured data, in addition to the flow determination, an empty pipe and bubble detection is implemented. Optionally, leakage detection can also be performed.
The ultrasonic flow sensor SQ-FM2PA61 (see picture) works largely independent of the temperature and electrical conductivity of the medium. The measuring principle works independently of position and almost without delay. It also allows for the determination of pulsating flows which, e.g., occur when using diaphragm pumps. The purely electronic sensor has no moving parts. It is therefore mechanically insensitive to excessive flow and has a high long-term stability.
The design of the flow sensor with nominal diameter DN10 and a measuring range of 0.3 to 30 l/min is modular in design and can therefore be easily and cost-effectively adapted to customer- and application-specific requirements. Typical applications are found e.g. in electronic water meters or in the monitoring of coolant in machine tools.
