Imported brands of electromagnetic flowmeter by the magnetic circuit system, measuring conduit, electrode, shell, lining and converter and other components.
Imported brands of electromagnetic flowmeter by the magnetic circuit system, measuring conduit, electrode, shell, lining and converter and other components, the flowmeter is suitable for measuring the volume flow of conductive liquids and slurries in the closed pipeline, such as clean water, sewage, a variety of acid, alkali and salt solutions, slurry, slurry, pulp, pulp, sugar syrup, and food aspects of the liquid and so on.
This product has a variety of types of structural forms and installation methods, structural forms of one-piece and split two types, installation methods of flange mounting, threaded mounting, clamp mounting, and its choice of measuring electrodes are also a variety of 316L is the basic type, to cope with the general aqueous media, there are tantalum electrodes, HaC, titanium electrodes can be applied to different measuring media, the pipeline in the lining of the ordinary rubber, PP, PTFE, can be adapted to measure different properties and temperature of the medium.
The use of imported brands of electromagnetic flowmeter should first understand these:
1, the flowmeter should be selected at any time to measure the conduit can be filled with liquid position for installation, in order to prevent the measurement of the conduit is not liquid and produce the pointer is not in the zero point caused by the illusion. It must be installed vertically to reduce the liquid flow through the electrode bubbles caused by the error. If placed horizontally, the two electrodes of the flowmeter must be kept on the same level, in order to prevent sediment or air at the top of the pipe to insulate it.
2、If necessary, you can let the tube empty, the built-in empty tube detection line, will stop the totalisation and flow rate signal output.
3, in the anode protection of the flow of fluid in the pipeline, the installation of electromagnetic flowmeter, to follow the following points: in order to allow the fluid can be well grounded, to use the ground loop; sensor and pipe connected up, between the flange to have an insulating gasket, the screw should also be used on the insulating sleeve.
4, the converter should be installed to avoid AC and DC strong magnetic field and vibration, the ambient temperature of -2 ~ 5 ℃, and can not contain corrosive gases, relative humidity is not greater than 8%.
5, electromagnetic flowmeter should be installed in a dry indoor ventilation, avoid installation in the ambient temperature is too high, should not be subject to strong vibration, try to avoid equipment with strong magnetic field, such as large motors, transformers, etc., to avoid the installation of corrosive gases in the occasion, the installation of the location to facilitate maintenance, which is to ensure that the flowmeter normal operation of the environmental conditions.
6, in order to ensure that imported brands of electromagnetic flowmeter measuring tube filled with the measured medium, variable iterative must be installed vertically, the flow direction from bottom to top, especially for liquid-solid two-phase flow, must be installed vertically. If the site only allows horizontal installation, it must ensure that the two electrodes in the same level.
7, electromagnetic flowmeter should be installed at both ends of the valve and bypass.
8, in order to avoid interference with the signal, the signal between the flowmeter and the converter must be transmitted with shielded wires, not allowed to put the signal cable and power line parallel to the same cable steel pipe, the signal cable length generally shall not exceed 3m.
