    Description The MT100 is a thermal dispersion, industrial process grade air and gas multipoint insertion mass flow meter in a local probe/remote transmitter configuration. The instrument provides direct mass flow measuring and measures flow rate, totalized flow and temperature. An average of the individual flow signals (up to eight) gives an output signal that represents the total mass flow.

    MT100 Multipoint Flow Meter MAINTENANCE MAINTENANCE Warning: To avoid hazards to personnel, ensure that all environmental isolation seals are properly maintained. Warning: AC mains wiring is exposed when remote electronics enclosure is opened. Exercise caution when calibrating the instrument or opening the enclosure door.

  • Page 94: Power Fuse Replacement

    Make sure system power is OFF before replacing the battery. A 3-volt lithium coin cell battery powers the MT100 real time clock (RTC). Typical service life of the battery is two years. Replace the battery every two years with a type CR2450 coin cell battery. Figure 50 below shows the location of the lithium battery on the SB4 (main) board.

  • Page 96 TROUBLESHOOTING MT100 Multipoint Flow Meter Verify Standard vs. Actual Process Conditions The flow meter measures the mass flow rate. The mass flow rate is the mass of the gas flowing through a pipe per time. Other flow meters, such as an orifice plate or a pitot tube, measure the volumetric flow rate. The volumetric flow rate is the volume of gas per time. If the readings displayed do not agree with another instrument, some calculations may be necessary before comparing them.

    1. Verify the Delta R data sheet has the same serial number and group number as the flow meter calibration that is being verified. 2. Turn transmitter power OFF. 3. Disconnect a flow element sensor from the MT100 transmitter (TBx) and connect the FES-200 cable connector in its place. See Figure 54.
