The processing method of no flow signal output of electromagnetic flow meter

Abstract: The information on the processing method of the no-flow signal output of the electromagnetic flowmeter meter is provided by the excellent flowmeter and flowmeter production and quotation manufacturers. 1. Fault causes No-flow signal output can be roughly classified into five fault causes, which are (1) power failure such as power failure; (2) system failure of connecting cables (excitation circuit, signal circuit); (3) ) liquid flow conditions. More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the details of the article on the processing method of no flow signal output of electromagnetic flowmeters. 1. The cause of the failure The no-flow signal output can be roughly classified into five reasons for the failure, which are (1) power failure such as power failure; (2) system failure of the connecting cable (excitation circuit, signal circuit); (3) ) Failures in liquid flow conditions; (4) Failures caused by damage to sensor parts or measurement of the inner wall adhesion layer; (5) Failures in terms of damage to converter components. 2. Inspection procedure Check the flow of electromagnetic flowmeter without flow signal output. First, make a preliminary inspection and judgment according to the overall consideration of the process, and then carefully check and try to troubleshoot one by one. The sequence of inspections listed in the process is based on the following principles: (1) It can be observed or inquired to understand that those that do not require major operations come first, that is, easy first and then difficult; Its own priority requires the higher one to come first. If it is confirmed by preliminary investigation that it is the cause of the latter failures, a detailed inspection can also be made in advance. ①The analog annunciator is a specially designed instrument for debugging and checking the electromagnetic flowmeter, simulating the output signal of the flow sensor, such as the LDZM type of Huaqing Instrument. a. Start b. Check the power supply c. Check whether the power supply is powered on. , Check the integrity of the excitation coil j, check the ground resistance of the signal terminal k, check the lining layer and the above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Processing Method of No Flow Signal Output of Electromagnetic Flow Meter'
