directly proportional to the velocity of conductive liquid, magnetic flux density and width of conductor (interior diameter of flowmeter). Such induced electromotive force is detected by a pair of electrodes on the tube wall of the flowmeter, and the equation of induced electromotive force is as follows: U = K×B×V×D U: Induced electromotive force K: Instrument Constant... -

Separated converter dimensions 3× 7 The separated type is generally used in on-site maintenance and debugging reading inconvenient occasions, but also used in more severe applications, such as high-temperature fluids and vibration sources. On most occasions, the integrated and separated types can both meet the requirements. -

When wiring, select the corresponding power terminal to connect to the power line according to the product specifications, and then connect to the signal line according to the required output form. See Table 3 for the specific meaning of the integrated electromagnetic flowmeter wiring terminals. Table 6 Terminal definition of separated type Terminal Symbol Function... - Page 11 Figure6 Front and rear straight pipe installation In order to ensure the upstream piping conditions required for high accuracy measurement of the flowmeter, the piping installation as shown in the figure below is recommended. When there are valves at the front and rear of the flowmeter, the front and rear straight pipe must meet the front 5D and rear 2D installation methods at least, and the valve must be fully open, as shown in Figure 7.
- Page 12 Figure 10. Figure 10 When the flowmeter is installed at the back end of the valve and the valve is not fully open, the flowmeter and the back end of the valve need to ensure a straight pipe section of at least 10D, as shown in Figure Figure 11 Installation Direction When installing, the positive direction of liquid flow should generally be the same with the direction of the...

Figure 13 Flowmeter installation symmetrically with the pipe axis Sensor Grounding Since the voltage of inductive signal of electromagnetic flowmeter is small, it is easily affected by noise. Its reference potential must be the same to the measured liquid potential. Therefore, the reference potential of the sensor (terminal potential), the reference potential of converters and amplifiers are also the same to measured liquid potential, and the liquid potential have to be the same as the ground potential. -

9.2 Converter start-up The measuring instrument is composed of a sensor and a converter and is ready for immediate use when it is supplied. All operating data is factory set according to your order, please refer to the provided inspection report for details. After turning on the power, the flowmeter performs a self-check first. -
