Spirax-Sarco M800 flow computer, totalizer and indicator

The M800 gas flow computer receives signals from various pipeline transmitters and converts them to display flow,total flow,pressure and temperature. Flow computers operate with Gilflo,ILVA,linear flowmeters,vortex and orifice plates. The M800 can provide density compensated saturated and superheated steam with appropriate input pressure d\/or temperature transmitter. Operator-settable alarm limits are provided to warn when flow,temperature,or pressure exceeds or falls below specified limits. These alarms are shown on a graphic display and can be sent via 2 relays (see options below). The digital pulse output provides the standard signal quality or energy (per pulse).,4 - 20 mA analog output channels are also provided to allow retransmission of flow to a chart recorder or BMS system.,The M800 is also equipped with four independent timers,which are able to record the total flow and the time when peak flow occurs over a settable period of time. A customer-selectable security code is provided to avoid arbitrary tampering.
