1. What is the measuring structure of the flange mounted type? The so-called flange mounted vortex flowmeter is one of its measurement methods, and the flange mounted virtual macro installation is also the most commonly used and common structural measurement form. The body of the flange mounted vortex flowmeter does not have a connecting flange. Generally, when connected to the pipeline, the flowmeter is clamped between two specialized flanges and then bolted to the pipeline.

2. Technical parameters of plug-in vortex flowmeter

◆ Measurement medium: gas, liquid, vapor ◆ Connection method: flange card type, flange type, plug-in type ◆ Caliber specification: flange card type. Caliber selection: 25, 32, 50, 80, 100. ◆ Flange connected caliber selection 100, 150, 200 ◆ Flow measurement range Normal measurement flow velocity range Reynolds number 1.5 × 104~4 × 106; Gas velocity of 5-50m/s; The normal measurement flow range for liquid is 0.5-7m/s. The measurement ranges for liquid and gas flow are shown in Table 2; The steam flow range is shown in Table 3. The measurement accuracy is 1.0 level, 1.5 level, and 2.5 level. The temperature of the measured medium is normal temperature -25 ℃~100 ℃, high temperature -25 ℃~150 ℃ -25 ℃~250 ℃, which is easy to disperse. The output signal pulse voltage output signal is high level 8-10V and low level 0.7-1.3V. The pulse duty cycle is about 50%, and the transmission distance is 100m. The pulse current remote transmission signal is 4-20mA, and the transmission distance is 1000m. The instrument is used in a friendly environment. The temperature is -25 ℃~+55 ℃, and the humidity is 5-90% RH50 ℃. The material is stainless steel and aluminum alloy. The power supply is DC24V or
