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. Wiring method for Cologne flowmeter 485
The wiring method for Cologne flowmeter 485 is as follows.
.1、 Connect the A, B, and ground wires of the Yunjueheng RS485 bus to the macro head of the flowmeter, where the A and B wires are respectively connected to the RS485+a
2、 Next, we need to connect the A, B, and ground wires of the RS485 bus to the control system. After the connection is completed, we need to set the corresponding communication parameters in the control system, including baud rate, checksum, and stop bit, and finally debug and test them.
3. How is the ultrasonic flowmeter wired?
The wiring of ultrasonic flow meters is usually very simple, and the core is "matching the right place". Basic wiring process: Preparation: Power off operation! Ensure that the flow meter and system power are completely turned off. Finding interfaces: Find the wiring terminals or interfaces on the flowmeter converter (host), which are usually clearly labeled. Connect power supply: Connect the positive (L/+) and neutral (N/-) wires of the mains (such as 220V AC) or DC power supply (such as 24V DC) to the terminals labeled "POWER" or "Power Supply". Attention: Be sure to verify the voltage level required by the equipment! Output (if any): 4-20mA output: Connect to the terminal labeled "AO" or "4-20mA", used to connect DCS, PLC or recorder. Relay output: connected to terminals labeled "DO" or "Alarm", used for alarm or control. Communication interface: RS-485 and other communication lines are connected to terminals labeled "COMM" or "RS-485" for remote communication. Inspection: After wiring is completed, carefully check whether all cables are secure and ensure that there are no short circuits or looseness. Key points and reminders: Read the instruction manual first! There may be slight differences in the wiring methods of different models of flow meters, and the ins
