EPSISTEEM Flow meter for steam applications

Principle: EPSISTEEM is used as primary elements in flow measurement of liquid and gas according to the differential pressure principle.

EPSISTEEM flow meter with 5 holes combines a traditional single hole
orifice plate with a flow conditioner.

This means that straight pipe run up stream the flow meter can be
reduced from 20 times inner pipe diameter to 5 times inner pipe
diameter, which is crucial with limited space available.

Construction

Model ES1
The EPSISTEEM flow meter model ES3 consists of a primary element based
on the differential pressure principle with an all welded integrated condensing pot
arrangement, with transmitter mounting flange and the possibility to mount a 3 valve double flanged manifold

Model ES2
The EPSISTEEM flow meter model ES2 consists of a primary element based
on the differential pressure principle, an all welded  construction with integrated condensing pot arragement with an integrated 3 valve manifold

 

Model ES5
The EPSISTEEM flow meter model ES2 consists of a primary element based
on the differential pressure principle, an all welded  construction with integrated condensing pot arragement with an integrated 5 valve manifold

Installation requirements

The EPSISTEEM flow meter can be mounted in a horizontal or vertical pipe.
The condensing pot arrangement shall be mounted horizontally with the
outlet pointing downwards.

To insure high accuracy of measurement, long straight pipe runs upstream from the flow meter is necessary. The required straight pipe run
depends on the disturbance upstream. To maintain the 1,2% accuracy
the minimum straight pipe run upstream shall be 14 x inner pipe
diameter and 6 x downstream
If an additional inaccuracy of ½ % is acceptable the required straight
pipe runs are reduced to half of the above values.

Mass flow measurement of saturated steam is obtainable using EPSISTEEM with a multi variable differential pressure transmitter.
Mass flow measurement of super heated steam : ask for EPSISTEEM-MAS mass flow meter data sheet.
