1. Could someone please explain in detail the starting flow rate issue of the flowmeter? The more detailed the better.
The vortex flowmeter is a flow measurement instrument designed based on the Karman vortex principle, suitable for measuring the volumetric flow rate of gases, liquids, and vapors, as well as the volumetric flow rate or mass flow rate under standard conditions.. Its measuring medium includes but is not limited to gas, liquid, and vapor, with various connection methods including flange clamping, flange, and insertion, and a wide range of caliber options. The measurement range of the vortex flow sliding pin gauge is wide and suitable for fluids with Reynolds numbers between 1.5 × 104 and 4 × 106. For gases, the measurement range is 5-50m/s; The measurement range for liquids is 0.5-7m/s. In addition, the measurement accuracy of vortex flowmeter is divided into 1.0 level and 1.5 level, and it is believed that the temperature range of the measured medium covers normal temperature -25 ℃~100 ℃, high temperature -25 ℃~150 ℃ or -25 ℃~250 ℃. This flowmeter has two output modes: pulse voltage output signal and pulse current remote transmission signal. The high level of the pulse voltage output signal is 8-10V, the low level is 0.7-1.3V, the pulse duty cycle is about 50%, and the transmission distance can reach 100 meters. The pulse current remote transmission signal is 4-20 mA, with a transmission distance of 1000 meters. The working environment requirements for vortex flowmeters are relatively tolerant, with a temperature range of -25 ℃ to+55 ℃ and humidity of 5-90% RH below 50 ℃. The material selection of vortex flowmeter is diverse, including stainless steel and aluminum alloy. The power supply i

2. From performance to certification: Why has the TS certified vortex flowmeter become a market benchmark?
The vortex flowmeter with TS certificate has become a market benchmark due to its compliance, superior performance, wide applicability, and perfect service. The specific analysis is as follows:
1. Compliance and Authoritative Recognition TS certificate is a mandatory certification of special equipment (including design, manufacturing, installation, etc.) by the State Administration for Market Regulation, which proves that the product meets the requirements of the Special Equipment Safety Law and has the legal qualification for safe operation.
. In industrial scenarios, especially in high-risk areas such as pressure pipelines, the use of unlicensed products may lead to regulatory penalties or safety accidents. The vortex flowmeter with TS certificate has passed the national authoritative certification, which can effectively avoid such risks and ensure that users use it in compliance.Secondly, the vortex flowmeter with TS certificate is of reliable quality and superior performance. It strictly follows national standards in the production process, has a complete quality control system, and has stable and reliable performance.
