Orifice std refers to standard orifice sizes used in engineering. Types of taps include flange taps, corner taps, and D and D/2 taps.

• Orifice std refers to standard sizes of orifices used in flow measurement

• Types of taps include flange taps, corner taps, and D and D/2 taps

• Flange taps are used for large pipes, corner taps for small pipes, and D and D/2 taps for general applications

Pressure gauge operating range refers to the minimum and maximum pressure values that the gauge can accurately measure.

• Pressure gauge operating range is typically specified by the manufacturer.

• It is important to ensure that the pressure being measured falls within the gauge's operating range to ensure accurate readings.

• For example, a pressure gauge with an operating range of 0-100 psi should not be used to measure pres

Straight length requirements for orifice flow element ensure accurate measurement by allowing flow to stabilize before reaching the element.

• Straight length requirements typically range from 10 to 44 pipe diameters upstream and 5 to 22 pipe diameters downstream of the orifice.

• These requirements help prevent flow disturbances and ensure accurate measurement of flow rate.

• For example, if the pipe diameter is 4 inches, the ...read more
