what is bevel? why bevel required in orifice plate?
Answer Posted / mohammed abdul rahman
Orifice plates which are used in flow measurement are mostly concentric "square-edge" type. The bore of the orifice is not constant when one moves from the upstream side to the downstream side along the cross section. The bore size is constant for a few mm only and then expands till it reaches the downstream face. This inclined cut is called the bevel in an orifice.
The main reason to have a bevel in the orifice is to avoid turbulence thereby providing more accuracy to the measurement. Restriction Orifice plates are not beveled since their intent is to reduce the pressure only.

I was working on calibrating turbidity transmitters endress+hauser at effluent polishing plant.We calibrated using NTU buffers.What happened is that when we immersed the sensor, everytime we raise and lower the sensor gradually, the reading will vary.my question is that is there any specifications on what is the required distance from the bottom of the container with buffer to the face of the sensor?Is it ok to install the sensor in a medium which has turbulence specially if bubbles are present?
