Pressure gauge should be located within a distance of 4D to 7D on either upstream or downstream of the meter body. Pressure tap fittings must not protrude in the pipe. Tap holes must be burr free.
RTD Temperature tap must be placed on the downstream side of the flow meter and within a distance of 5D to 10D from the flow meter body (since a temperature measuring probe /thermo-well can interfere with vortex generation)
