Do turbine flow meters need maintenance and overhaul?
Every flow measuring instrument requires regular maintenance and repair every year, and turbine flow meters are no exception..
2. 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.
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 pressure loss caused is small. The LUGB vortex flowmeter produced by Chengfeng Company is based on the Kalman vortex street principle, mainly manifested by setting a non streamlined vortex generator (blocking fluid) in the flowing fluid, and alternately generating two columns of regular vortices from both sides of the vortex generator. Widely applicable to the measurement and control of superheated steam, saturated steam, compressed air, general gases, water, and liquids in industries such as petroleum, chemical, metallurgical, thermal, textile, and papermaking.
