STEEMCO Flow meter for steam applications

Principle: STEEMCO is a velocity flow meter used as primary elements in flow measurement of steam according to the differential pressure principle

Features:

Construction

Model ST1
The STEEMCO flow meter model ST3 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 ST3
The STEEMCO flow meter model ST2 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 ST5
The STEEMCO flow meter model ST2 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 STEECMO 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 obtainbable using STEEMCO with a multivariable transmitter

Mass flow measurement of super heated steam. See EMCO’s STEEMCO-MAS mass flow meter
