Abstract: how to choose the suitable scale vortex flowmeter information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The first vortex flowmeter is based on the principle of the karman vortex street, when gas to meet spiral body triangular prism produces karman vortex, record through vortex piezoelectric ceramic probe into frequency signal, can calculate the flow is treated through signal board value. Vortex flow. More flow meter manufacturers choose model price quote you are welcome to inquire, here's how to choose the suitable scale vortex flowmeter article details. The first vortex flowmeter is based on the principle of the karman vortex street, when gas to meet spiral body triangular prism produces karman vortex, record through vortex piezoelectric ceramic probe into frequency signal, can calculate the flow is treated through signal board value. Vortex flowmeter can be used for moisture measurement. At present, a lot of application is the measurement of steam. Vortex street flowmeter measurement advantage is small pressure loss, easy installation and use, measurement is more accurate. Vortex flow meter for measuring the steam of vortex street flowmeter generally need to bring warm pressure compensation, because the steam temperature and pressure is in change at any time, only measure the accurate temperature and pressure can be calculated vapor density value, so that to calculate the mass flow rate accurately. Temperature compensation and fission compensation voltage compensation generally fall into an organic whole, integrated the advantages of compensation is convenient installation and beautiful, but the accuracy is influenced. Because a size measurement of temperature and pressure have no direct contact and media. But the deviation is related to the product design and quality of each manufacturer, such as our manufacturers kyokuto vortex flowmeter instrument and meter plant temperature sensor is installed at the bottom of the probe and the actual deviation, almost no pressure deviation is very small. Accuracy, of course, compared with a shape or size of vortex flowmeter is more accurate, it is a separate temperature transmitter and pressure transmitter installed on the pipe is measured, the measurement result is more close to the real value. Imports such as E + H, rosemount vortex flowmeter accuracy and stability of general precision can be 0. 75% and 1. 0%, this value is the theoretical value, the actual precision is difficult to achieve, and the price is higher than domestic several times. Domestic vortex flowmeter can achieve such accuracy. So you don't worship things blindly, on the choice according to the site condition and its accuracy and stability requirements for selection. Vortex flowmeter are domestic product quality is good and bad are intermingled, of course, these several reasons, one is the machining for the vortex probe thread cutting technology, processing of vortex street flowmeter whether level off, good probe traffic no fluctuations, bad quality of probe to measure the flow rate will fluctuate. The stand or fall of the circuit boards of vortex flowmeter is also a factor, 8 bits MCU circuit board without the circuit boards of 16 strong anti-interference, USES a 16 chips, better anti-jamming performance and stable performance. Not because the flow of small vibration and produce substantial fluctuations. Affect the stand or fall of vortex street flowmeter and the stand or fall of prover. Some small workshop is almost no identification device, so there is precision. In addition to the standard table to calibrate some company is controlled, often in order to save cost and not the real standard table, so accuracy is not high also. We kyokuto both reference standard table calibration instrument and meter plant identification device, also have a sonic nozzle flow calibration, so the accuracy and stability is can be guaranteed. Vortex flow meter professional manufacturer huawei sailing automation instrument above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
