Don’t recognize the flow meter

What kind of flow meter is this? I need expert guidance
A flow meter with a differential pressure element is installed inside the pipeline, with two pressure taps connected to a differential pressure transmitter. It could be a built-in orifice plate, it could be balanced type, it could be a V-cone, it could be various types of valves, or... there are many possibilities. Isn’t it specified on your construction drawings or PID diagrams?
Insertion-type flowmeters are generally barometric or balanced type flowmeters that use differential pressure for measurement. As for precision? It’s a bit worse
DeltaBar flow meter, issue resolved
I’ve learned it; why is it named Ba Lei?
It’s a differential pressure type anyway; I don’t know its internal structure
Ba means Bar, which is the English translation for stick. The gauge, as a pressure or differential pressure measuring instrument, is rod-shaped and inserted into process pipelines; it gets its name from its shape. There are several holes in the bar; pressure is transmitted to the sensing element through these holes. Special instruments are used to measure the pressure and pressure difference, and by applying Bernoulli’s principle regarding the relationship between fluid flow velocity and pressure difference, the flow velocity of the fluid inside the pipe can be determined. This device is commonly used in large-diameter circular tubes or square ducts; due to its simple design and easy installation, it is employed for high-flow measurement in factories, although its accuracy is slightly lower than that of other similar devices.
