The Spirax Sarco M841 flow computer can be used in conjunction with ILVA piping units for the measurement of a wide range of media, including steam, water and compressed air. Available in a variety of mounting configurations for wall and panel mounting, the M841 provides density compensation for saturated and superheated steam and displays cumulative flow, instantaneous flow, temperature, pressure, and density in response to incoming pressure or temperature signals.<\/p>\n
Suitable for vapors, gases and liquids.
\nAccording to the temperature and pressure values, the steam is automatically judged to be in a superheated or saturated state, and the density value is obtained by checking the table respectively.
\nAutomatic density compensation, temperature compensation, Reynolds number compensation and expandability factor compensation.
\n0.1 level accuracy, high definition true color LCD display, with small flow billing, stopping steam judgment, over plan consumption billing, power outage record, paperless record function, to meet the trade settlement measurement needs.
\nIt can automatically save 65536 groups of the latest historical data, and the saving interval can be set, and use real color to draw the historical curve of instantaneous flow, fluid temperature and fluid pressure.
\nReal-time clock and timed automatic meter reading function.
\nThe password setting prevents unauthorized persons from changing the set data.
\nWith screen saver function to prolong the life of the screen.
\nPower failure data is not lost, power failure data protection without backup battery, protection time 10 years.<\/p>\n
