A pulse signal transmission of vortex flowmeters connection
Three-wire system output frequency signal flow sensor used DC24V power supply, or vehicle with DC12V power supply only usually by three core are connected to the display instrument or computer shielded cable, shielding layer should be reliably received amplifier shell, the grounding screw in the field environment that suits the shielded cable should be selected, additional shielding cable should separated from other strong power lines, not parallel to the line,
Second, the standard 4 ~ 20 ma vortex flowmeter signal wiring
Standard 4 ~ 20 ma output signal of the two wire transducer used DC24V power supply, usually by two core are connected to the display instrument or computer shielded cable, shielding layer should be reliably received amplifier shell, the grounding screw in the field environment that suits the shielded cable should be selected, additional shielding cable should separated from other strong power lines, not parallel to the line,
3. With 485 communication interface functions of vortex flowmeters connection
With RS - 485 communication function of vortex flow meter used DC24V power supply, and other equipment adopts four wire transmission way,
