1. Correct wiring method for vortex flowmeter
The correct wiring method for vortex flowmeter is as follows: power line wiring: clarify the power requirements of the vortex flowmeter and select the appropriate power line. Connect the positive pole of the power cord to the "+" end of the flowmeter and the negative pole to the "" end. Ensure the polarity of the power cord is correct to avoid equipment damage. Signal wiring: The output signal of a vortex flowmeter is usually an analog signal of 420mA. Connect the positive pole of the signal line to the "420mA+" terminal of the flowmeter and the negative pole to the "Lujin 420mA" terminal. Ensure that the shielding layer of the signal line is grounded to reduce the impact of electromagnetic interference on the measurement results. Attention: Ensure that all wiring terminals are securely fastened to avoid measurement errors or equipment malfunctions caused by poor connections and poor connections. Avoid threading power lines and signal lines in the same conduit to reduce electromagnetic interference. If on-site debugging or maintenance is required, the power supply should be cut off first to ensure safety.
2. Wiring method between vortex flowmeter and flow integrator
The wiring between vortex flowmeter and flow integrator needs to ensure signal type matching and correct parameter setting. The core steps include signal type confirmation, wiring operation, parameter setting, and compensation calculation.
. Here are the specific methods:1. Signal type confirmation and preparation before wiring. Vortex flowmeter signal requirements: The output signal must be proportional current (4-20mA), not square root signal, and the range must be set to volu
2. Wiring steps Power connection: Provide independent power supply (usually 24V DC) for the vortex flowmeter and flow integrator, ensuring correct polarity (positive pole connected to "+", negative pole connected to "-").
. If the flowmeter requires an external temperature/pressure sensor, connect the power supply and signal line according to the sensor manual. Current signal line connection: Connect the current output terminals (usually labeled as "I+" and "I -") of the vortex flowmeter to the current input terminals (labeled as "AI+" and "AI -") of the flow integrator. Ensure that the shielding layer of the signal line is grounded to reduce interference. Compensation signal wiring (if required): Temperature compensation: If an external temperature sensor (such as PT100) is used, connect its signal wire to the temperature input terminal of the integrator (marked as "TI+" and "TI -"). Pressure compensation: If an external pressure transmitter (output 4-20mA) is used, connect its signal line to the pressure input terminal of the accumulator (marked as "PI+" and "PI -").III. Parameter Setting: Basic Setting of Flow Accumulator: Differential Pressure Setting: Fixed at 1.000 (corresponding to the linear range
