1. Wiring Instructions for Vortex Flow Meter
The vortex flow meter sensor adopts a three line inspection system: power supply, signal, and power ground. Use three core shielded cables. The shielded wire is connected to the housing ground at one end of the sensor. Do not connect the secondary instrument terminal to the ground. Connect the three cores to the power supply, signal, and ground of the monitoring (Ω) power supply respectively. The transmitter in Figure 10 is a two-wire system: using a two core cable, the "+" and "-" terminals of the vortex street are respectively connected to the+24V and the "+" terminal of the test instrument signal input, and the "-" terminal of the signal is connected to the 24VDC "-" terminal. The output of this circuit is 4-20mA. See Figure 11
2. Why is power distribution required when connecting the Di Yuan vortex street flowmeter to the lubrication flow integrator? How to connect the power distribution lines? Connect From the diagram, it can be seen that the wiring is done using a two-wire system, which means that there are only two wires from the module to the field instrument or transmitter. These two wires serve as both power and signal lines. Power distribution is to supply electricity to the vortex street. If there is no power supply, the vortex street will not work. To put it bluntly, the integrator supplies power to the vortex street at+24V, and the vortex street outputs a 4-20mA current signal to the integrator. The signal transmission is all done through these two wires. On the first picture, there is no problem with the wiring. On the second picture, the red lines on terminals 6 and 23 are redundant and useless. The integrator in the second picture should have
3. Wiring instructions for vortex flowmeter
The sensor of vortex flowmeter is designed with a three wire system, including power line, signal line, and power ground line.
. This design uses a three core shielded cable, where the shielded wire is connected to the ground of the housing at the sensor end. It is worth noting that Bi should not regret connecting the shielded wire to the ground at the secondary instrument end. The specific function of each wire is: the power line provides power, the signal line transmits data, and the power ground wire is connected to the ground terminal of the sensor. These three wires correspond to different functions, ensuring the normal operation of the equipment. The transmitter adopts a two-wire design and uses a two core cable. In the vortex street transmitter, the "+" terminal is connected to the+24V power supply, while the "-" terminal is connected to the signal input "+" Binance lifting terminal of the test instrument. The signal "-" end needs to be connected to the "-" end of a 24V DC power supply to form a 4-20mA current loop. This design enables vortex flowmeters and transmitters to work efficiently and accurately, especially in environments with limited power supply. By reasonable wiring and connections, interference can be minimized to the greatest extent possible and measurement accuracy can be improved. Proper wiring is crucial in practical applications. Incorrect wiring can not only cause equipment to malfunction, but also pose a safe
