Don't change the cause of the metal flow meter scale pointer

Abstract: the change of metal flow meter scale pointer is not information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Metal flow meter site maintenance, often see flow indicator is changeless, is fixed on a certain value. Judgment method is quickly, will be on the remote display section to change its position with the rotor part of the up and down, dynamic traffic simulation float state. With this. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the change of metal flow meter scale pointer is not the article details. Metal flow meter site maintenance, often see flow indicator is changeless, is fixed on a certain value. Judgment method is quickly, will be on the remote display section to change its position with the rotor part of the up and down, dynamic traffic simulation float state. Metal float at this time is fixed, using the float magnetic principle, monitor the follow-up magnetic steel and the float coupling linkage if the float is stuck, mobile display part of the pointer to function change, according to the evidence that part of the normal. If the pointer cannot change for remote display and signal power failure. The cause of the problem has the following aspects: 1. Pointer ( 1) Damage to squeeze the pointer stuck metal flow meter glass panel. Processing method is: open display table to replace glass panel; ( 2) Vibration, while other equipment maintenance or instrument repair touch attack instrument pointer loose deformation, distorts the pointer value cannot reflect the real traffic. Processing method is: replace with same type display table to install. 2. Pointer jitter ( 1) Metal flow meter pointer for piping and medium wave will produce slight fluctuations. ( 2) Piping and medium because of unstable operating pressure cause a larger wave; Causes can look for operation and control room above, adjusting process parameters and stable pressure, temperature, flow, increase the damping metal float flowmeter, improve the technological environment make flowmeter is stable. 3. Signal power failure ( 1) Signal amplification conversion parts damage failure; ( 2) Loose screw transmission line fault; ( 3) DCS control station terminal fault; ( 4) Control station I / 0 module failure. Troubleshooting method is: use & other; Segmentation & throughout; In the control room control station set terminal after measuring voltage DC ( 1 - 5) V, analysis the judgment is a field failure or control failure, zui high failure rate is terminal screw loose, tighten screw fault can be ruled out. Fault cannot be ruled out according to the terminal, find DCS fault measurement module, search module failure indicator, see if there is a failure, also can use & other Substitution method & throughout; Replacement of the same model measuring module replacement, to see if display is normal. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
