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. What are the characteristics of remote vortex flowmeter?
The functional characteristics of the remote vortex flowmeter include several points under the good attack car
1. The meter also integrates temperature and pressure compensation function in the body, which can measure the standard volume flow rate or standard mass flow rate of the fluid
2. Fully intelligent and digital circuit design, which can automatically compensate for the density or standard volume calculation of the measured fluid
3. Accurate and reliable measurement of flow rate, and more convenient use and operation.
.3. Principle of Vortex Flow Meter
Vortex flow meter is a volumetric flow meter developed and produced based on the Karman vortex flow principle to measure the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids.
. Mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, steam, and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low main
