WebCoriolis Flow Meter Principles. The basic operation of Coriolis flow meters is based on the principles of motion mechanics. As fluid moves through a vibrating tube it is forced to accelerate as it moves toward the point of peak-amplitude vibration. Conversely, decelerating fluid moves away from the point of peak amplitude as it exits the tube. WebThe flowmeter assembly consists of a particulate filter, upstream meter run (if applicable), the flowmeter body, and the downstream meter run with appropriate sensing taps (P f, T f) and sampling connections.The required flowmeter assembly dimensions follow a conservative design based on the following criteria: • A particulate filter. • Proper piping …

WebThese meters also provide a greater extended low-flow accuracy compared to mechanical meters across a wide range of pipe sizes with no pressure head loss and no moving parts to maintain. These devices offer a lot of connectivity and there are a variety of output options, such as tying into a programmable logic controller (PLC). WebThe upstream piping required in this case is 5D or 10D diameters upstream of the flow conditioner, then the flow conditioner, and an additional 10 D between the flow conditioner and the meter. There is a new design of flow conditioner permitting the distance between the flow conditioner and the ultrasonic meter can reduce from 10D to 7D.

WebIt is available for all pipe sizes, and if the pressure loss it requires is free, it is very cost-effective for measuring fluid flows in larger pipes (over 6" diameter). The orifice plate is … WebOct 12, 2015 · Installing the flowmeter 10 diameters downstream of two elbows out of plane (per the rule of thumb) would cause the flowmeter to not measure accurately. On the other hand, some flowmeters measure accurately with no upstream straight run — regardless of the upstream piping configuration. Therefore, each flowmeter has its own …
