Electromagnetic flow meter alarm phenomenon and solution

Abstract: Electromagnetic flow meter alarm phenomenon and solution information are provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. When the user uses the electromagnetic flowmeter, there will be an alarm phenomenon occasionally, and the other party will naturally think that there is something wrong with the flowmeter? In fact, specific problems need to be analyzed in detail. The alarm phenomenon of electromagnetic flowmeter often has the following three misunderstandings: False. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the electromagnetic flowmeter alarm phenomenon and solutions. When the user uses the electromagnetic flowmeter, there will be an alarm phenomenon occasionally, and the other party will naturally think that there is something wrong with the flowmeter? In fact, specific problems need to be analyzed in detail. The alarm phenomenon of electromagnetic flowmeters often has the following three misunderstandings: Misunderstanding 1: Electromagnetic flowmeter excitation alarm and system alarm are electromagnetic flowmeters broken? System alarm: SYS——The system excitation alarm is also called the excitation alarm. In fact, the excitation alarm and the system alarm are the same thing, sometimes called the system excitation alarm, which belongs to the excitation signal alarm detected by the intelligent electromagnetic flowmeter. When customers encounter such a situation, most It is caused by the excessive vibration of the pipeline, or the open circuit of the excitation coil caused by the water entering the junction box during use. Electromagnetic flowmeter system alarm solution: The solution is also very simple, the user can use a multimeter to detect the continuity of the excitation circuit to judge, the specific terminals are EXT+ and EXT—For these two terminals, measure whether there is resistance, and determine the reason for the disconnection of the excitation circuit by judging the resistance. Specific judgment criteria: the resistance value of the excitation coil will not exceed 200Ω. There is also a battery-powered electromagnetic flowmeter. Its excitation alarm is to detect the resistance value of the excitation coil. Although an excitation alarm will occur, it will not affect the measurement results. The user can solve this phenomenon by setting the excitation method. Misunderstanding 2: The electromagnetic flowmeter empty pipe alarm is that the electromagnetic flowmeter is faulty? ATC alarm: FGP——Fluid Empty Pipe Alarm Intelligent electromagnetic flowmeters generally have empty pipe detection functions and do not require additional electrodes. When the user selects the empty pipe alarm, when the fluid in the pipe is lower than the measuring electrode, the intelligent electromagnetic flowmeter can detect an empty pipe state. When the empty pipe state is detected, the analog output and digital output signals of the instrument Both are 0, and the meter flow display is also 0. The significance of the electromagnetic flowmeter empty pipe alarm is that the customer can know the flow status of the medium in the measuring pipe in real time, and even the empty pipe full pipe status, especially suitable for those opaque pipe sections. It is the most convenient and fast for users to judge the fluid in the pipe. It reflects the humanized and intelligent design of the intelligent flowmeter. Therefore, the electromagnetic flowmeter empty pipe alarm is not a malfunction of the electromagnetic flowmeter, but a truthful reflection of the fluid condition in the measurement pipeline. Of course, users can choose to disable this setting according to their needs. Misunderstanding 3: Is the electromagnetic flowmeter over-range? FQH——Flow upper limit alarm FQL——Flow lower limit alarm The flow upper limit and lower limit alarm are calculated according to the range percentage of the flowmeter. This parameter reflects whether the user exceeds the set range in a specific flow range. It does not mean that the electromagnetic flowmeter exceeds the measurement range, only It is the percentage of the range set by the electromagnetic flowmeter. The setting is emphasized here because the range of the electromagnetic flowmeter can be set. Sometimes it is to improve the resolution of the output signal of the electromagnetic flowmeter. Therefore, the upper and lower limit alarms of the electromagnetic flowmeter are alarmed. , the user can set it according to the actual needs of the measurement. If it is not necessary, you can also choose to turn it off. It is mainly used as a prompt for customer-specific traffic. The specific solutions are as follows: The upper and lower limit alarms indicate that the output current and output frequency or pulse are all over the limit. After changing the flow range to larger or smaller, cancel the upper and lower limit alarms. Electromagnetic flowmeter, a domestic high-end flowmeter brand, takes customer demand as the first priority, and puts quality first, so that customers can use it with confidence.
