Orifice Plates Series ISB/1

Orifice Plates ISB/1

The EMCO Orifice Plate Series for insertion between orifice flanges according to ANSI B 16.36 with RF or RTJ facing.
Material in stainless steel as standard, others on request.
The plates are calculated according to ISO 5167, ASME MFC-3M or other international standards.

Principle

EMCO orifice plates are used as primary elements in flow measurement of liquid, gas and steam according to the differential pressure principle.
