Advantages and disadvantages of vortex flowmeter
Advantages of vortex flowmeter:
1. Suitable for gas, steam and liquid applications.
2. Insensitive to fluid conductivity.
3. Its pressure drop is usually lower than that of orifice flowmeter.
4. For pipes smaller than 6 inches, it is usually much cheaper than orifice flowmeter because it does not need impulse line and does not need any super existing pipe
Special antifreeze protection of the road.
Disadvantages of vortex flowmeter:
1. Vortex flow meters require turbulence to operate and will stop reading as the fluid transitions from a turbulent state to a transitional or laminar state. This is called an instrument
The "low flow cut-off" point below which flow measurement is impossible. (see more information below.)
2. Vortex flowmeter is effective (if unexpected) to start the filter. The vortex shedding rod (blunt body) on the ruler is very suitable for catching bolts and drinks
Cans, oyster shells and various other sundries. When a substance is caught by the body, the meter either does not read accurately or does not read at all.
3. - some vortex flow meters use small end C] to measure eddy current. These may be blocked by aggregates or solids, making the instrument unable to work properly. vortex
The design of measuring sensors is the main difference between instruments. The sensor design will allow some instruments to work in some applications, while others cannot.
4. For vortex flowmeter, high vibration or entrained solids may be a problem. It can detect and count solid particles or vibrations as if they were solid particles
It's actually flowing. (note that most instruments have a "noise band" or similar adjustment that can be set to suppress these vibrations, but this
It will reduce the sensitivity of the instrument and significantly increase the low flow cut-off point.)
5. Like orifice flowmeter, vortex flowmeter needs upstream and downstream flowmeter to establish a good flow profile. This operation shall not be less than 15 upstream
Diameter and 5 downstream diameters, but most suppliers want to see at least 25 upstream diameters and 10 downstream diameters
6. Vortex flowmeter measures volume flow, not mass flow. It can calculate the mass flow based on the assumed density, but if the fluid density changes
If there is a change, the reading will be wrong.
More than 6 inches of line, the economic advantage of vortex flowmeter will decline.
