Orifice DP Flow DDM
SKU: DDM
Manufacturer: Kirchner & Tochter
The DDM orifice is designed to measure and control the flow of liquids and gases.The differential pressure at the orifice is proportional to the square of the volume rate of flow through the pipeline. The DDM-DN orifice is fitted between flanges in the pipeline. The DDM-Rp/Gi/Ga orifice is installed in the pipeline using pipe unions or with either internal or external thread.

Operating Principle
A differential pressure arises at a pipe constriction, which is proportional to the square of the flow rate through the pipe.
The resulting differential pressure can be recorded with a meter and can be directly indicated as flow rate on a scale.
