1. The impact of vortex flowmeter
The output of the two-wire (4-20) mA signal is transmitted to other devices using a two-wire system, requiring a power supply of 24V ± 10%, and the maximum load resistance of the output circuit is 600 Ω (including the resistance of the cable). Generally, 600VPVC insulated wires or cables are used for connecting wires; In sites susceptible to electrical noise interference, a two core shielded wire (RWP2 × 0.5mm) should be used, and the shielding layer should be reliably connected to the grounding screw inside the amplification spring plum box. The temperature of the vortex flowmeter has little effect on the amplifier. When used to measure high-temperature liquids or when frequent pipeline cleaning is required, the sensor can be inverted. On pipelines with insulation layers, do not use insulation materials to surround the connecting rod of the sensor connected to the amplifier box, at most not exceeding one-third of the height of the connecting rod. The sensor housing can be wrapped with insulation material. Vortex flow meters should be avoided from installation on very long overhead pipelines, as the sagging effect of the sensor can easily cause leakage between the sensor and the flange after long-term use. If installation is necessary, pipeline fastening devices must be installed separately at 2D locations upstream and downstream of the sensor. The installation of pipelines should be free from strong vibrations, otherwise necessary shock absorption measures should be taken. Install rubber stripping and pipeline fastening devices at the upstream and downstream 2D positions of the sensor, and add shock-absorbing pads. The minimum flow rate of a vortex flowmeter is often lower th
2. Do you know what precautions should be taken when using a vortex flowmeter?
Proper use and installation are crucial for vortex air flow meters, as they reduce the probability of problems. Next, let flow meter manufacturer Qingtian Instrument explain the precautions for installing vortex flow meters..
1、 The flowmeter should be installed indoors. If it needs to be installed outdoors, measures should be taken to avoid direct sunlight and rain.
2、 Flow meters should be avoided from being installed in places with strong magnetic field interference, small space, and inconvenient maintenance.
3、 Flow meters should be avoided from being installed in environments with high temperatures, equipment thermal radiation, or corrosive gases. If installation is necessary, insulation and ventilation measures must be taken.
4、 Flow meters should be avoided from being installed on pipelines with mechanical vibrations. If installation is necessary, shock absorption measures must be taken, such as installing flexible hoses for transition, or installing pipeline fixing support points and shock-absorbing pads at 2DN upstream and downstream of the flow meter.
5、 After spot welding the fl
