Regarding gas pipeline flow measurement
Thread Content
To measure the flow rate of coke oven gas, with normal temperature, pressure of twenty to thirty kilopascals, and a pipe diameter of 600; the gas contains coal tar, dust, etc. What type of flow meter would be suitable?
An insert-type vortex street – I’m not sure if that’s feasible.
1. The orifice plate is subject to pressure variations, but the pressure tap tubes are prone to being clogged by tar and dust. 2. In vortex flow meters, the small components used for measuring vortex frequency can become inaccurate if they get covered with tar; the vortex generators are also affected. 3. I don’t have any experience regarding the impact of tar on thermal mass flow meters; moreover, high-quality such meters are quite expensive. 4. Insertion-type target flow meters, from a structural and functional perspective, seem to be an ideal choice, and their price is moderate.
There is no information available on plug-in target flowmeters; one equipment manufacturer usually uses venturi tubes
Insertion-type orifice flow meters, such as Anuo Ba and Bito Ba, should be ordered with a backflushing interface.
