1. Share the wiring method of the two-wire system for vortex flowmeter?

For the two-wire wiring method of the vortex flowmeter, please refer to the attached diagram. When you open the junction box, you can see a row of wiring terminals on the green circuit board. The first group is connected to the positive+24V power line, and the second group is connected to the current output signal accompanying wire. The two-wire wiring method here is 24V+and current I+. If this is a combination wiring, that is, the wiring method for the 4-20mA output of the two-wire system, be sure to pay special attention when wiring and do not connect it incorrectly.

2. 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.

3. Is the flow meter in front of the five finger arrow or behind the arrow?

The first five and the last three refer to the straight pipe section distance of 3 or 5 times the diameter (unit) in front or behind the rock search surface where the pipeline is opened. For example, if the flow meter is DN100, there should be a 5 * 100mm straight pipe section at the front and a 3 * 100mm straight pipe section at the back to ensure proper distance. Refer to Wang Shens figure for calculation method:
