Abstract: the use of vortex flow meter scale points and installation requirements of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Vortex street flowmeter: first, some selection of vortex flowmeters in diameter selection or due to the change of process conditions after the design selection, before making the choice of a little bit big, actually should choose the diameter as small as possible, in order to improve the measuring precision, thus. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the use of vortex flow meter scale points and installation requirements for details. Vortex street flowmeter: first, some selection of vortex flowmeters in diameter selection or due to the change of process conditions after the design selection, before making the choice of a little bit big, actually should choose the diameter as small as possible, in order to improve the accuracy of measurement, the resulting problems are: ( 1) : indicates that the long-term inaccurate; ( 2) Instructions: wide fluctuations, not reading; ( 3) : big traffic instructions can also, small flow indicator is not allowed. The process condition change is only temporary. Can be combined with the parameters of setting to improve accuracy of instructions. Two: the installation of ( 1) : the length of straight pipe in front of vortex flowmeter is insufficient, affect the accuracy of measurement, instructions are not allowed to be for a long time. For example: the straight pipe in front of the sensor, because FIC203 not used for metering, used only for control, all the current accuracy of using equivalent to degrade. Three: parameters setting direction ( 1) Parameter error makes the secondary instrument full frequency calculation error, indicating no, always without instructions, long-term instrument K coefficient can not be sure, many data are not consistent. ( 2) : full frequency almost makes instructions are not allowed to be for a long time, the actual full frequency gets calculation of full frequency makes instructions from wide fluctuations, readings, and material parameters on the inconsistency of zui will affect the parameters again, such issues need to calibration, determine parameters are compared with each other, to solve the problem. Four: secondary instrument failure ( 1) Directions: no, never, etc. , this part of the fault is more, including: a circuit board have break line, vortex street flowmeter range set individual who display bad, K coefficient set individual who bad, make uncertain range setting and K coefficient setting, etc. With the appropriate repair of fault, the problem is resolved. Five: four routes road connection ( 1) : part of the loop line connection is very good on the surface, and check carefully, some loose joint has actually led to the suspension of circuits, although some joint connection is tight but due to line problem tighten screw fastening on the line of leather, also makes the circuit interruption, this part mainly vortex flowmeter and always no instructions. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
