Product description:

The probe of capacitive vortex flow sensor is composed of a pair of differential capacitance. The vortex force generated by the vortex generator is alternately applied on both sides of the probe, so that the differential capacitance of the probe can be changed into an electric pulse signal through the amplifier. The unique internal structure of the probe has good anti vibration performance and measurable minimum flow. The matrix probe of imported ceramic capacitor plates under the high temperature of more than 1 thousａnd degrees, so the high temperature characteristics, process, structure and components of the core components of the detection at home and abroad are essentially different, higher reliability. Intelligent sensor with gas and liquid, frequency automatic tracking, no potentiometer or toggle switch to adjust the frequency bａnd and sensitivity, zero drift, range set free, truly realize the site debugging. The circuit has the function of restraining the vibration frequency, enhancing the anti vibration performance and the wired function, and its comprehensive performance is better than the similar products at home and abroad. If the design flow and the actual condition of flow deviation, the flowmeter can not work normally, most cases of CN321 can not change the pipeline under the condition of nozzle type vortex flowmeter can replace the same specification. · wide range of working temperature · anti vibration · good performance; the lower limit of low flow rate · range wide · · specifications; high precision · installation conditions; the sensor should be installed horizontally or vertically (flow direction from top to bottom) with nominal pipe diameter on the corresponding. · the upstream and downstream of the sensor should be equipped with a straight pipe length, the length should meet the requirements of the following table. · flow control valve should not be set on the upstream side of the sensor. · if the upstream straight pipe length can not meet the requirements, it is recommended that the user in the upstream pipeline installation of fluid rectifier. · the sensor should not be installed in the pipeline has strong vibration, so as not to affect the precision, such as the installation used in the pipeline vibration when can adopt the following measures to reduce the interference brought by vibration. 1, in the sensor upstream 2D fixed support points; 2, in order to meet the requirements of the straight pipe section, the installation of excessive hose. · when the sensor is installed on the high temperature pipeline, the transmitter must be installed vertically downwards.
