What are the uses and characteristics of electromagnetic flowmeters?
The universal flow calculator is a versatile and versatile multi-purpose flow calculator. In addition to conventional fluid temperature compensation, pressure compensation, density compensation, and temperature and pressure compensation, the instrument also has the following functions.

1 to compensate for the compression coefficient Z of the general gas;
2 super compression factor F for natural gas. Make compensation
3 compensate the nonlinearity of the flow coefficient;
4 compensate the expansion coefficient of the differential pressure flowmeter;
5 Check the steam density and make corresponding compensation;
6 Measure the dry part flow of the wet gas.
The mass storage in the meter can store the latest historical data of 11520 groups in turn, which is beneficial for reference and telephone meter reading in measurement management.
In the hardware structure shown in Figure 7.8, the process channel has a fluid temperature and pressure input channel in addition to the flow signal input channel.
The information flow shown in Figure 7.9 shows the information transfer relationship and signal processing sequence for implementing its main functions.
The function of the instrument is more powerful than that of the FC 3000. It not only completes the calculation and auxiliary functions of the FC 3000 instrument, but also has the following calculation functions.
(1) Fluid working condition compensation function Most flowmeters can only guarantee measurement accuracy if the fluid working conditions are consistent with the design conditions. Some fluids, such as gases and vapors, have a significant impact on measurement accuracy due to changes in fluid conditions.
Compensation must be made.
Depending on the flow sensor type and fluid type, different operating parameters and different compensation formulas can be selected. The compensation formula and implementation method of the current constant month are described below.
