Consult a flow meter for measuring pipeline wind speed
Thread Content
Dear colleagues, our factory has a 250KW blower with a pipe diameter of DN600. The instrument used for measuring wind speed was originally a LUGB-2350 vortex flow meter, but it wasn’t very reliable and often malfunctioned; therefore we want to choose a different model that can provide a 4-20MA output. Please share your suggestions.
Measure the flow rate? Thermal type, Ba type.
There is also an insertable multi-trachea type
. A back-to-back pitot tube flow meter – I think that will work.
To select the appropriate model, you must provide the maximum flow rate, normal flow rate, minimum flow rate, medium composition, allowable pressure loss, and whether corrosion is present. It is certain that vortex streets are not good.

Our company has many successful cases of using vibration-resistant insert-type vortex flow meters in air ducts. As long as the seismic performance is good, it is possible to measure the low-density, low-velocity air in the ducts; if necessary, we can discuss this further.
With such a large diameter, I think an ABB flow meter can be used
Aoniuba, Weiliba, Bituoba are all fine
