14. 3 75 All 27 74 19 and above 27 73 All Abstract The SICK FLOWSIC600 ultrasonic flowmeter determines the linear gas velocity through the meter tube by using multiple acoustic pulse paths The flowmeter analyzes these paths employing the delta time travel measurement method The OMNI Flow Computer either totalizes the flowmeter pulse input signal or determines the flowrate from the serial port data received from the flowmeter This device communicates with OMNI Flow Computers via OMNI s SV process I O combo module using a proprietary protocol To use the scaled pulse output of the SICK FLOWSIC600 the flow computer must have at least one B or E combo module installed FLOWSIC600 Ultrasonic Flowmeter Theory of Operation SICK s ultrasonic gas flow metering technology incorporates multiple pairs of transducers into a smart digital inferential instrumentation device This device is installed into a gas pipeline system to measure gas flow Each pair of transducers emits ultrasonic acoustic pulses that travel bi directionally to and from each transducer in the pair Up to four pairs of transducers are positioned across the meter so that the path between each transducer has an axial component i e one transducer is upstream relative to the other Pulses emitted by the downstream transducer are slowed down by the velocity of the gas With flow the pulse takes longer to travel to the upstream transducer than with n
