What are the wiring methods for flow meters? Hello, Yangpai Technology, an intelligent oil and gas metering system service provider, is pleased to answer your question. There are several wiring methods for flow meters, each with its specific application scenarios and advantages: series wiring method: connect one end of the power cord to the "+" pole on the flow meter interface, and the other end to the "+" pole on the switch or sensor. Connect one end of the power cord to the "-" pole on the flowmeter interface and the other end to the "-" pole on the switch or sensor. Three wire wiring: suitable for situations where temperature compensation is not required. Connect the positive pole (+) of the power supply to the red wire of the flow meter. Connect the negative pole (-) of the power supply to the black wire of the flow meter. Connect the signal acquisition cable, usually a white wire. Four wire wiring: Compared to three wire wiring, it has temperature compensation function, which can improve the accuracy of flow meters. Connect the positive pole (+) of the power supply to the red wire of the flow meter. Connect the negative pole (-) of the power supply to the black wire of the flow meter. Connect the positive pole (+) of the temperature compensation cable to the blue wire of the flow meter. Connect the negative pole (-) of the temperature compensation cable to the white wire of the flow meter. The wiring method of electromagnetic flowmeter: three wire method: red wire connects voltage output signal, black wire connects current output signal, and white wire connects ground wire. Four wire method: On the basis of three wires, add a shielded wire to reduce noise and connect it to the instrument housing. Two wire method: It is relatively simple, with red and black wires connecting the current output signal and ground wire respectively. However, it should be noted that this wiring method requires the Quelv gear to measure the conductivity of the medium above a certain value, otherwise the measurement accuracy will be affected by residual noise. Connection method of pipeline: flange connection: a commonly used connection method, suitable for various flow meters, such as electromagnetic flow meters, turbine flow meters, etc. Threaded connection: It is commonly used for pipe diameters smaller than DN50 and is widely used in the medical and food industries. Clamp on connection: Simple and convenient, this connection method is commonly used in vortex flowmeters. Clamp connection: suitable for small diameter and low working pressure pipelines, easy to install and disassemble quickly. In summary, there are various wiring methods for flow meters, and the specific choice of method needs to be comprehensively considered based on factors such as the type of flow meter, application scenarios, and measurement requirements. During the selection and installation process, relevant technical specifications and safety operating procedures should be followed to ensure the accuracy and service life of the flowmeter.

2. Installation requirements for straight pipe section of steam vortex flowmeter

The installation requirements for straight pipe section of steam vortex flowmeter are as follows: the basic installation direction and concentricity dispersion require the flowmeter to be installed horizontally on the pipeline, and the allowable pipeline inclination angle is within 50 degrees.
