Electromagnetic flow meter scale installation considerations

Abstract: the electromagnetic flow meter scale installation note information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Electromagnetic flowmeter measurement principle is not dependent on the characteristics of the flow, if the line has some turbulence and vortex in the measurement zone has nothing to do with the measurement. A, installation location cannot have big vibration source, and reinforcement measures should be taken to stabilize the instrument near the pipe. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the electromagnetic flowmeter scale installation considerations article details. Electromagnetic flowmeter measurement principle is not dependent on the characteristics of the flow, if the line has some turbulence and vortex in the measurement zone has nothing to do with the measurement. A, installation location cannot have big vibration source, and reinforcement measures should be taken to stabilize the instrument near the pipe; B, not installed in large transformer, motor, pump and large magnetic field near the equipment, such as from the interference of electromagnetic field; C, sensors and pipeline connection should guarantee the full tube operation, good zui vertical installation; D, transmitter shell, shielded cable, ontology and at both ends of pipeline to ground, grounding electrodes should be set up separately, grounding resistance should be less than 10 ohms, not received electrical grounding or public online; E, requires before five times after 3 pipe diameters of straight pipe. If there is a steady state of the eddy current in the measurement zone will affect the stability of measurement and measurement precision, then can increase the length of the straight pipe before and after, using a flow stabilizer or reduce the number of measurement point section at a steady velocity distribution. Flow meter can be installed in a horizontal and vertical, but should make sure to avoid sediment and bubble influence on measuring electrode, electrode axial level as well. Vertical installation, fluid flows from bottom to top. Sensor cannot be installed in the pipeline zui high position, the position of the accumulation of bubbles. To ensure that the flow sensor in the measurement, the pipeline is filled with flow body, cannot appear the full package. Such as pipeline is not full package or exports have empty state, the sensor should be installed on a siphon. Electromagnetic flowmeter are the requirements for a conventional straight pipe before 10 d after 5 d, with the help of bent pipe, valve, respectively, have different requirements. Within the electromagnetic flowmeter grounding: electromagnetic flowmeter measurement electrode in a dc or ac field, if the environment can not be effectively shield in a no interference conditions, has serious interference on measurement. Sensor enclosure grounding or not, is directly related to the accuracy of measurement and stability, and the grounding conductor must not pass any interfering voltage, so the electromagnetic flowmeter requires very reliable grounding, grounding should be blocked, otherwise it will produce interference electric current. However, the benefits of the electromagnetic flowmeter grounding: if the connection pipes of sewage flowmeter is ( Compared with the measured medium) Insulation to use ground ring, its material should be selected according to measured medium corrosion. If it is ptfe sensors, in order to protect the flanging teflon is not damaged, should choose grounding ring. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
