Abstract: The inspection information of the turbine flow meter before installation is provided by the excellent flow meter and flow meter manufacturers. ZK-LWGY series turbine flowmeters are widely used to measure closed pipelines with stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum AI2O3, hard alloy without corrosion, and without fibers, particles and other impurities, the kinematic viscosity at working temperature is less than 510-6m2/ s liquid, viscous for movement. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are some points to check the details of the turbine flowmeter before installation. ZK-LWGY series turbine flowmeter is widely used in the measurement of closed pipeline with stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum AI2O3, hard alloy without corrosion, and without fibers, particles and other impurities, 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, and it can also be used for quantitative control, over-amount alarm, etc. It is an ideal instrument for flow measurement and energy saving. After installing the turbine flowmeter, be sure 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 turbine 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. 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, easily pollute 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. When the contact resistance changes, it indicates that the turbine flowmeter electrode is 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 normal operation of the instrument The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'A few points to check the turbine flow meter before installation'
