1. What is the wiring method of the flowmeter? The wiring method of the flowmeter may vary depending on the type and brand. Here are two common wiring methods for flow meters for your reference.
1. Wiring method for split type flow meters: As shown in the above figure, the sensor and accumulator of the split type flow meter are installed separately and connected through signal cables. When wiring, it is necessary to connect the output signal of the sensor to the input terminal of the integrator. Generally speaking, the wiring method of a split type flowmeter is relatively simple. Simply connect the corresponding signal line to the integrator.
2. Wiring method of an integral flowmeter: As shown in the diagram, the integral flowmeter integrates the sensor and integrator together without the need for signal cables.
. When wiring, it is necessary to connect the output signal of the sensors dead end finger to the input terminal of the integrator. The wiring method of the integral flowmeter is relatively simple, just connect the corresponding signal line to the accumulator. It should be noted that different types of flow meters have different wiring methods, so it is necessary to carefully read the user manual of the flow meter before wiring to understand the correct wiring method. At the same time, safety should be taken into account during the wiring process to avoid contact with live parts or dangerous operations.

2. Schematic diagram of the working principle of an insertion type electromagnetic flowmeter

The insertion type electromagnetic flowmeter works based on Faradays law of electromagnetic induction, and its core principle is to calculate the flow rate by measuring the induced electro

motive force generated by the movement of a conductive liquid in a magnetic field.

. The following is a detailed explanation and diagram of the working principle: When a conductive liquid passes vertically through magnetic field lines with a magnetic field strength of B at an average flow velocity V, if the distance between two fiber electrodes is L, according to Faradays law of electromagnetic induction, an induced electromotive force E will be generated between the electrodes. The formula is: E=K × B × L × V, where K is the instrument constant (determined by factory calibration and cannot be modified by the user); B is the magnetic induction intensity of the excitation coil that causes damage, collision, and breakage; L is the distance between two electrodes; V is the average flow velocity of the fluid; Q? Is the volumetric flow rate of the measured fluid (proportional to the flow velocity V). By measuring the electromotive force E and combining it with known parameters K, B, and L, the volumetric flow rate Q in the pipeline can be calculated. The working principle diagram illustrates that the excitation coil generates a constant magnetic field (magnetic induction intensity B) perpendicular to the fluid flow direction. Electrode: inserted into the inner wall of the pipeline with a spacing of L, used to detect induced electromotive force E. Conductive liquid: flowing at an average flow velocity V, cutting magnetic field lines to generate electromotive force. Conversion display: Built in instrument constant K, receives electrode signals and calculates volumetric flow rate Q?. The key parameter relationship between electromotive force E and flow velocity V is proportional: E ∝ V. The relationship between volumetric flo
