What are the differences in usage between the split-type and integrated electromagnetic flowmeters? Is there a difference in performance? This post was last edited by wwxxss_1 on 2009-2-18 at 18:11.]
There is no difference; it’s just that the split-type converter can be placed in a location free from vibration and interference.
There is no fundamental difference; in actual installation, split-type instruments can sometimes be more convenient. For example, the sensing unit can be installed on the pipe rack while the transmission unit can be placed on the ground for easier maintenance
There isn’t much difference; it depends on whether you need on-site instructions or not. Integrated types are generally installed in locations where reading is convenient and the conditions are favorable, while separate types are usually used in places where direct reading or monitoring is difficult (such as overhead pipelines). There is not much difference in terms of usage; for the separate type, the converter and sensor need to be connected by a cable.
Split installation is troublesome, while integrated installation is simple； The split-type can have a deep-water version, but the integrated type doesn’t. Additionally, split-type units have poor interference resistance, as there is an extra signal wire between the sensor and the transmitter; their performance in areas with strong interference is not as good as that of integrated units.
What was said on the 3rd floor is correct; there is no fundamental difference. In actual installation, split-type instruments can sometimes be more convenient – for example, the sensing part can be installed in the pipe rack while the transmission part can be placed on the ground for easier maintenance
There is no difference in measurement. The separation facilitates observation by the user. However, it has many connections, requires extensive maintenance, and is prone to interference. There are also certain limitations on the installation distance, which vary among different manufacturers.
It mainly depends on the requirements of the on-site environment
Depending on the design environment and conditions, choose a split or integrated type. Separation requires a signal cable connection, which reduces the anti-interference capability!
The split-type design is generally used because the temperature in the installation site is relatively high; the transmitter section, which contains many electronic components, cannot withstand high temperatures. By placing the transmitter part away from areas with high temperatures, it is possible to avoid such issues. However, this design requires high standards for cable shielding, as even minor damage to the cables can cause problems； The integral type is used in areas with lower temperatures where heat dissipation is relatively easy.
There are still differences in selection; the split-type design can reduce certain interferences at the installation site. For example, the interference caused by frequency converters and high-voltage components on the instrument itself, or the impact on the instrument’s lifespan in complex environments.
