Insertion plates

Application

Orifice plates BLS 100 are used to measure the flow of aggressive and non-aggressive gases, vapors and liquids, especially in large pipelines.

Designs

Blanking disk with attached grip label for direct installation between pipe flanges or orifice flanges (see below). Depending on the process conditions, it can be run as

Standard orifice plate

Quarter circle nozzle

Segment cover

Orifice plate with conical inlet

Double cone diaphragm

Further product information

Differential pressure tapping

A distinction is made between flange pressure tapping and pipeline tapping. The pressure is tapped at a defined distance from the panel. In special cases, the effective pressure can also be tapped in a standard-like manner as a corner tapping in the flange.

Measurement uncertainty

Depending on the application, the measurement uncertainty is approx. 0.5% – 1.2% of the flow coefficient.

Orifice flanges

Orifice flanges are flanges specially developed for flow measurement based on the differential pressure principle. The pressures are tapped through a hole in the flange at a defined distance before and after the orifice plate. Orifice flanges are manufactured according to ASME B 16.36 or DIN 19214 as standard. Other standards (e.g. NORSOK, JIS) can also be considered.
