Model ST1
The STEEMCO flow meter model ST1 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 ST3 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 ST5 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
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 obtainable using STEEMCO with a multivariable transmitter. Mass flow measurement of super heated steam. See EMCO’s STEEMCO-MAS mass flow meter
