The SFMc-150 flow meter is applicable for measuring flow rates of saturated and superheated steam, mass flow rates of Boiler feed Water in closed conduits. It is best suited for applications where affordability, reliability and ruggedness are of prime concerns.
It can be used as heat energy transfer meter to measure thermal energy using various fluids which are being used as the heat transfer medium.
In the conventional system of measurement, the differential pressure generated by orifice plate is measured by DP transmitter. The output from DP transmitter after square rooting is accepted as proportional to flow rate. This assumption is true only when the density is constant. Unfortunately, the density of the compressible fluid is never constant. The density of compressible fluid changes with line pressure and line temperature. Thus, introducing errors in flow rate measurement.
Features of Steam Flow Meter:
|Well established standards||Available||Not Available|
|Suitability for high pressure & temperature application.||Most suitable||Seal fails in the majority of cases after the certain duration|
|Installation||Easy to install||Critical & expensive because of Requirement of specially machined pipe lengths.|
|Existing pipeline modifications for installation||No modifications required.||The design is based on velocity & not on line size. As a result, customer line size & selected flow meter size may differ.|
|Recalibration of transmitter||Easy & can be done in-house||Has to be done on a flow-rig and hence is expensiv|
