Insert type electromagnetic flow meter scale how to correctly install

Abstract: insert type electromagnetic flow meter scale how to correctly install information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. A straight pipe, 3 d5d ( D for pipe diameter) , all types of valves, elbow in front, after you install the instrument, enough to make sure there is a straight pipe, is in line with the general principles for flow patterndistribution pipe installation tea is inevitable, as much as possible. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a plug-in electromagnetic flowmeter scale article details how to properly installed. A straight pipe, 3 d5d ( D for pipe diameter) , all types of valves, elbow in front, after you install the instrument, enough to make sure there is a straight pipe, is in line with the general principles for flow patterndistribution pipe installation as tea is inevitable, reducer, flowmeter, should be put before the pipeline, 10 d, all kinds of valve 90 & deg; 5 d bend, straight tee the general requirements of the pipe diameter. Second, the installation position and direction of the sensor is installed vertically zui as the ideal, but must pay attention to the fluid flow. Must be horizontal axis horizontal electrodes. As an axis vertical electrode, gas in upper electrode simple dirt and impact contact electrode, electrode includes the following scale, easy to set the fluid, the surface errors such as this. Location is liquid, at any time, at zero measuring tube. In order to prevent the illusion caused by program, you need to select measuring liquid catheter. The design of the pipeline, it is necessary to make sure that you don't create bubbles, air bubble liquid flowmeter, therefore, in order to prevent the throttle valve to reduce the effect of pressure in the pipeline, upstream of the valve you need to install it. In order to avoid the measurement error of sensors around the electromagnetic interference ( For example, high power motor, transformer, etc. ) It is impossible to have. Three, grounding potential electromagnetic flowmeter to measure fluid circuit as the determination of zero potential, most of the opportunities, the electrical connection in the vortex precession flowmeter by point grounding of sensor output signal and flow volume measurement of liquid, the halfway point of the grounding potential input converter. In addition, the output signal of electromagnetic flowmeter sensor, the velocity of 2. 5 ~ 8. 0 mv full scale is very small, only very small, the output is slight interference, there are only a few millivolts, outside, you affect the accuracy of the meter and the world. In order to reduce the electrical interference, in order to ensure the normal operation of the electromagnetic flowmeter, electromagnetic flowmeter has the good earth [ 1] 。 Electromagnetic flowmeter on the ground, you should pay attention to the following points. （ 1) Tube sensor, shell, shielded wire, converter and secondary instrument measurement must be grounded [ 1] 。 （ 2) Sensors, must be grounded to an independent converter, absolutely, the resistance of motor is connected to the ground, process piping, must be less than or equal to 10 & Omega; ( 1] 。 （ 3) Converter in the field of grounding, shielding equipment control room above ground multiterminal the secondary side of the ground, will go to don't need to avoid introducing various interference [ 1] The possibility of. （ 4) Ground wire can connect sensors installed in a metal tube, sensor, depending on the manufacturer's requirements, the pipe flange side to form a reliable grounding loop ( See figure 1) You are. The ground equipment, it must be a separate grounding, grounding line and other electrical equipment connected together is not allowed. Four, piping, 1) To eliminate the flange to beat and fracture, the installation flow timing should tilt or correction of the pipeline, plastic pipe flow meter and the installation of the distance deviation between two flanges. If the installation on the long overhead lines, flow meter between the two flanges should have the bearing support line, prevent pipeline vibration stress. （ 2) Foreign body eliminate the pipe welding slag, etc. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
