OVAL TURBO STEAM METER

Transcription

1 Steam Turbine Flowmeter for Saturated Steam OV TURBO STEM METER Mini: GSM Standard: GS, GSV GENER This Turbo Steam Meter is specifically designed and built for the measurements of saturated steam consumption at the end of steam line and is capable of directly indicating the total consumption in kilograms over a wide range. When coupled to a pulse generator, it also makes remote total count obtainable. In view of today, s increasing steam cost, this instrument will contribute to attaining significant energy saving through reasonable measurement management. GSM type (orizontal mount) GS type (orizontal mount) GSV type (Vertical mount) FETURES. Wide flow range and high measuring accuracy. 2. By exchanging the flow diverter nozzle, flow range can be changed without removing the meter from pipe line.. Meter count can be seen locally, and output signal for remote totalization is available too. 4. Manual pressure adjusting device or utomatic Pressure Compensator (PC) is optionally available for actual readout. 5. Robust and simple configuration makes the maintenance easier.

5 TURBO STEM METER GBT0E- INSTTION Mini Type (GSM): orizontal only Standard (GS, GSV): orizontal or vertical Straight pipe sections of 0D upstream of the meter and 5D downstream of the meter are required as minimum. This applies in piping with bypass lines also. Before starting operation, make sure to fill up the reduction gear chamber with clean antifreeze solution, particularly in winter time to avoid freezing. Suitable concentration of the antifreeze is described in the meter instruction manual. Typical piping layout 5D min. 0D min. Flow direction D: Piping I.
