Analysis of what routine inspections need to be carried out before the operation of the turbine flow meter

Abstract: Analysis of the routine inspection information that needs to be carried out before the operation of the turbine flow meter is provided by the excellent flow meter and flow meter manufacturers. ZR-LWGY series turbine flowmeter is a new generation of turbine flowmeter with the characteristics of simple structure, light weight, high precision, good repeatability, sensitive response, convenient installation and maintenance, etc. Widely used for measurement. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the article that analyzes the routine inspections that need to be carried out before the operation of the turbine flowmeter. ZR-LWGY series turbine flowmeter is a new generation of turbine flowmeter with the characteristics of simple structure, light weight, high precision, good repeatability, sensitive response, convenient installation and maintenance, etc. It is widely used in the measurement of stainless steel 1Cr18Ni9Ti, 2Cr13, corundum AI2O3 and cemented carbide in closed pipelines, which does not corrode, and has no impurities such as fibers and particles. The kinematic viscosity at working temperature is less than 5.×10-6m2/s liquid, for kinematic viscosity greater than 5×The liquid of 10-6m2/s can be used after real-liquid calibration of the flowmeter. If it is matched with a display instrument with special functions, it can also perform quantitative control, over-amount alarm, etc. It is an ideal instrument for flow measurement and energy saving. After installing the turbine flowmeter, don't rush into it yet. First, check whether there is any problem with the wiring of the installation box. If a problem is found, it should be dealt with in time, so as to ensure the normal use in the future. Due to the lack of operating experience of some personnel, it is necessary to carefully study the turbine flowmeter manual. Be good at analyzing and thinking about the problems encountered in the initial operation. The whole set of electromagnetic flowmeter has been adjusted and calibrated on the flow calibration device of the manufacturer. As long as the matching number of the sensor and the converter, and whether the instrument coefficient is correct, etc., the turbine flowmeter can be put into operation without any adjustment. Messed up the whole set of instruments that had been adjusted. Before the instrument is put into operation, the turbine flowmeter sensor must be filled with the actual measurement medium, and the zero point adjustment should be made in a static state after power-on. After being put into operation, it is also necessary to stop the flow to check the zero point regularly according to the medium and the conditions of use. Especially for the non-clean medium that is easy to precipitate, easy to contaminate the electrode, and contains solids, more inspections should be carried out in the early stage of operation to gain experience and determine the normal inspection period. For qualified users, several basic parameters of the sensor should be measured and recorded before the turbine flowmeter instrument is put into operation. These data are very helpful for the analysis of the reasons for the failure of the sensor after a period of operation. When the contact resistance of the two electrodes changes, it indicates that the turbine flowmeter electrodes are likely to be contaminated; if the contact resistance increases, the contamination may be insulating deposits; if the contact resistance decreases, the contamination may be conductive Deposits; the contact resistance of the two electrodes is asymmetrical, indicating that the two electrodes are polluted differently; the decrease in the insulation resistance of the electrodes and the excitation coil indicates the degree of dampness of the turbine flowmeter sensor; when the insulation resistance drops to a certain extent, it will affect the meter of normal work. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
