Heater Electronic and Electrical Components
Coriolis Meter Interface Board (M10030A001)
The Coriolis Meter Interface Board interfaces the Coriolis Meter and Pump CPU, as well as to
the Freeze Sensor. The meter receives a 24 V input from the 24 V power supply and supplies
5 VDC logic power to the Temperature Control Board. The meter can handle up to two
Coriolis Meter inputs. However, only Side A is used on a commercial dispenser.

The Coriolis Meter contains electronics within the meter that monitor the function of the meter
and create pulses in proportion to the volume of flow through the meter. A Coriolis Meter
Interface Board provides power to the meter as well as accepts pulses and diagnostic data from
the meter that are processed and directed to the standard PCN. Additional functions of the
Meter Board are to provide power to the Heater Control Board and to accept input from the
Pump Freeze Sensor.
