These differential pressure flowmeters are the most common in use. They find their use in measurements with liquids, gases or steam in various industries. They are suitable for many operating conditions, common ones (water supply, swimming pool, etc.) as well as for high pressure and temperature (steam pipes, hydrocarbons, etc.) and aggressive fluids. They are very reliable for natural gas or wet gas measurements, and economical. Differential pressure flow-meters are suitable for a wide range of piping dimensions.

The device works according to the principle of differential pressure which is proportional to the square of the volume rate of flow through the pipeline. The DDM-DS11 series integrates an orifice plate inside an armature for wafer mounting or with threaded fittings The low and high pressure outlets on either side of the diaphragm are connected to a gauge in accordance with customer specifications.

The reliability of the measurement depends of the flow behaviour at the measuring point. The region of steady flow should covers piping distances of 6 ND upstream and 4 ND downstream.
