Alarm occurs when using the electromagnetic flow meter scale

Abstract: the use of electromagnetic flowmeter scale alarm occurs when the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. When using electromagnetic flowmeter, occasionally appear alarm phenomenon, it is naturally associated with the flow meter where a failure? Actually, analyzing the specific issues that need to be electromagnetic flowmeter alarm phenomenon often has the following three misunderstandings: myth. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the use of electromagnetic flowmeter scale alarm occurs when the article details. When using the electromagnetic flow time, occasionally appear alarm phenomenon, it is naturally associated with the flow meter where a failure? In fact, analyzing the specific issues that need to be electromagnetic flowmeter alarm phenomenon often has the following three misunderstandings: myth: excitation alarm and alarm system of electromagnetic flowmeter is electromagnetic flowmeter is broken? The system alarm: SYS— — Excitation system alarm, also will be exciting alarm actually excitation alarm and alarm system is one thing, sometimes also called system excitation alarm, belong to the intelligent electromagnetic flowmeter intelligent testing of excitation signal alarm, when customer encountered such a situation, majority is because the pipeline vibration is too large, or in the process of using water be affected with damp be affected with damp cause excitation coil caused by open circuit wiring box. Electromagnetic flowmeter system alarm solution: the solution is simple, the user can get judged multimeter test excitation circuit on and off, specific terminal for EXT + and EXT— The two terminals, measuring whether there is resistance, through determine the cause of the resistance size to determine the excitation circuit disconnection. Specific criterion: excitation coil resistance is not more than 200 & Omega; 。 There is also a case belongs to the battery type electromagnetic flowmeter, its excitation alarm is the detection of excitation coil resistance, although there will be a exciting alarm, but does not affect the measurement result, users can set the excitation mode to solve this kind of phenomenon. Myth 2: electromagnetic flowmeter atc alarm is electromagnetic flowmeter failure? Atc alarm: FGP— — Fluid atc alarm intelligent electromagnetic flowmeter is generally have atc detection function, without additional electrodes. When a user in choosing atc alarm, when the flow in the pipeline is lower than the measuring electrode, the intelligent electromagnetic flowmeter can detect a atc state, when detect the state of atc, instrument of the analog output and digital output signal is 0, and instrument flow is 0. The significance of electromagnetic flowmeter atc alarm is that customers can know the real-time measurement of the flow of the medium in the pipeline, even tube hollow tubes with state, especially applicable to those opaque section, for the user to determine the fluid pipe zui for convenient and quick, embodies the humanization and intelligent design of intelligent flowmeter. So the electromagnetic flowmeter atc failure alarm is not electromagnetic flowmeter, but truthfully reflect the situation within the fluid. Of course the user can choose according to need to ban this setting. Myth 3: electromagnetic flowmeter flow limit alarm and flow limit alarm of electromagnetic flowmeter was range? FQH - — Flow limit alarm FQL— — Flow limit alarm flow and the lower limit alarm is in accordance with the flowmeter calculated as a percentage of the range of this parameter is to reflect the user in a particular flow range exceeds the range of concrete manifestation, doesn't mean the electromagnetic flowmeter is beyond the measuring range, the percentage of the counts as electromagnetic flowmeter set range, set stressed here because of the electromagnetic flowmeter range can be set up, and sometimes in order to improve the resolution of the output signal of electromagnetic flowmeter, so for the electromagnetic flowmeter, the lower limit alarm on the phenomenon, the user can according to the actual measurement need to be set, if you feel there is no need, also can choose to shut down, it is mainly used for a hint of specific volume of customers. Specific solution is as follows: the lower limit alarm prompt for output current and output frequency or pulse is overrun. After the flow range and change is small, cancellation, the lower limit alarm. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
