Electromagnetic flow meters are primarily used for measuring conductive liquid media; they cannot be used to measure gases, vapors, or liquids containing a large amount of gas. Affected by the flow velocity distribution, under axisymmetric conditions, the flow rate signal is proportional to the average flow velocity. Therefore, a certain length of straight pipe sections before and after the electromagnetic flowmeter is also necessary. Prone to external electromagnetic interference. The performance in use is influenced by many factors. The truthfulness, reliability, and accuracy of measurements depend not only on the converter but, more importantly, on the sensor; furthermore, the excitation technology of the sensor has a significant impact on flow measurement. The advantages of Qingtian Instrument’s electromagnetic flowmeters are as follows: (1) They have a simple structure, with no moving parts or disturbances/throttling elements that could impede the flow of the measured medium; thus, they are less prone to issues such as pipe blockages and wear when dealing with sticky or solid-liquid two-phase media. It can compensate for the limitation of mass flow meters in measuring such media. (2) An electromagnetic flowmeter is a device for measuring volumetric flow rate, and its measurement is not affected by changes in the fluid’s density, temperature, pressure, viscosity, Reynolds number, or conductivity within a certain range. Electromagnetic flowmeters need only be calibrated using water as the test medium; they can then be used to measure other conductive liquids without any additional corrections. This is an advantage that other flow meters do not have. (3) Electromagnetic flow meters have a very wide measurement range; some products offer a measurement range of up to 1000:1. For sensors of the same diameter, the full scale range can be set arbitrarily as long as the medium flow velocity remains within the range of 0.3 to 15 m/s. The measurement range of electromagnetic flow meters can cover both turbulent and laminar flow velocity distributions, which is unmatched by differential pressure flow meters, turbine flow meters, vortex flow meters, and other types of flow meters. (4) The measurement principle is linear; it features high measurement accuracy and entirely electrical signal output. It has a fast response speed, enabling the measurement of pulsating flow as well as rapid accumulation of total volume. (5) It has good corrosion resistance. (6) In principle, it measures the average flow velocity in the flow cross-section; thus, there are relatively low requirements for the velocity distribution. Therefore, the length of the straight pipe sections before and after the sensor is required to be shorter than that for other flow meters. (7) Can measure fluid flow in both forward and reverse directions. The above are the advantages of Qingtian Instrument electromagnetic flowmeters as provided by the manufacturer. You can use this information as a reference; it is hoped that it will help users understand more about maintenance methods, thereby reducing measurement errors during use. Regular maintenance of the instruments can effectively improve their performance. Qingtian Instruments http://www.zgqtyb.com
