Kind of signal parameter, while measurement parameter is fed back into DCS control systems, facilitate DCS control systems show real-time flow,
Temperature, pressure value, so that operations staff observes.
3rd, the utility model eliminates flow integrator of the prior art, changes and completes to calculate by DCS control systems, saves
Cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model includes fluid line 1 and DCS control systems 9, fluid line 1 is provided at both ends with
Flange, the left end of fluid line 1 is liquid feeding end, right-hand member is outlet end, and whirlpool is provided with the liquid feeding end of fluid line 1
Device 2, baffle 7 is installed in the outlet end of fluid line 1.
Liquid input section 1-1 that fluid line 1 includes setting gradually, internal diameter are less than the undergauge section 1-2 of liquid input section 1-1 internal diameters and interior
Footpath is more than the extension diameter section 1-3 of undergauge section 1-2 internal diameters, and pressure is provided with the fluid line 1 between undergauge section 1-2 and extension diameter section 1-3
Electric transducer 6, the middle part outside fluid line 1 are provided with element mounting box 8, the He of pressure sensor 3 are provided with element mounting box 8
The test side of temperature sensor 5, temperature sensor 5 and pressure sensor 3 is extended in fluid line 1, and pressure sensor 3 is installed
Above undergauge section 1-2, temperature sensor 5 is installed on above extension diameter section 1-3,
The top of element mounting box 8 is provided with terminal box 4, and binding post 4-1, pressure sensor are provided with terminal box 4
3rd, temperature sensor 5, the output line of piezoelectric transducer 6 pass through binding post 4-1 and the DCS control system 9 in terminal box 4
Connection.
Operation principle of the present utility model：After fluid is by eddy generator 2, fluid is forced in eddy generator 2
The heart acutely rotates, and forms eddy-currents.Eddy-currents accelerates, and streamwise is after undergauge section 1-2, flow strength enhancing.Work as whirlpool
After stream enters extension diameter section 1-3, secondary rotating motion, i.e., secondary whirlpool precession occur for the whirlpool under the backflow effect of baffle 7.
The frequency of secondary whirlpool precession is directly proportional to flow, and in very wide range of flow, the frequency of secondary whirlpool and flow into
Linear relationship.The frequency of the secondary whirlpool can be measured by piezoelectric transducer 6, temperature sensor 5 and the also convection current of pressure sensor 3
The temperature and pressure of body monitor in real time and the data of the temperature measured, pressure, the frequency of secondary whirlpool is transferred into DCS
Control system 9, DCS control systems 9 obtain outflow instantaneous value, DCS controls system after the computing of Clapyron Equation formula and processing
System 9 carries out real-time display to the temperature and pressure value of flow instantaneous value and fluid simultaneously.
