1. Which is better for measuring the flow rate of diesel, vortex street or V-cone?
What flowmeter is better for measuring diesel or other oil media? For diesel with low viscosity, we recommend commonly used and cost-effective vortex flowmeters and turbine flowmeters. Zaizha code is suitable for some oils with high viscosity, such as engine oil. So can we use vortex flowmeter and turbine flowmeter? The answer is definitely no. Speaking of which, why does Chai Nian have such advantages when using a vortex flowmeter for diesel? Here, we need to analyze the characteristics of the vortex flowmeter. Only in its features can you find the advantages of the vortex flowmeter and feel why we recommend using it for measuring diesel. The principle of vortex flowmeter is based on the principle of Karman vortex street. In terms of structural construction, it is a vortex generator inside the pipeline. The fluid passes through the vortex generator to generate Karman vortex, and the instantaneous frequency of the fluid is calculated by the sensor. The cost of vortex flowmeter is relatively cheaper than other flowmeters. The vortex flowmeter also has some outstanding characteristics in terms of usage:
1. The volumetric flow rate is not affected by thermal parameters such as temperature, pressure, density, or viscosity of the measured fluid.
2、 No movable parts, simple measuring element structure, reliable performance, long service life
3. High accuracy, repeatability of 0.5%, and low maintenance.
4、 Can measure the flow rate of liquids, gases, or vapors
5. Generally does not require separate calibration
6. Wide measurement range. The range ratio can generally reach 1:10
7. The pressur
2. The difference between turbine flowmeter and intelligent turbine flowmeter
Turbine flowmeter consists of turbine, bearings, preamplifier, and display instrument.
. The principle of a turbine flowmeter is to place a turbine in the center of a pipeline, supported by bearings at both ends. When the fluid passes through the pipeline, it impacts the turbine blades, generating a driving torque for the turbine, which overcomes the friction torque and fluid resistance torque to produce rotation. Within a certain flow range, for a certain viscosity of the fluid medium, the rotational angular velocity of the turbine is proportional to the fluid flow velocity. Therefore, the fluid flow velocity can be obtained from the rotational angular velocity of the turbine, and the fluid flow rate through the pipeline can be calculated. The rotational speed of the turbine is detected by a sensing coil installed outside the casing. When the turbine blades cut the magnetic field lines generated by the permanent magnetic steel inside the casing, it will cause changes in the magnetic flux in the sensing coil. The sensing coil sends the detected periodic change signal of the m
