The FlowScaie transmitters' oroorammable functions are partitioned into
1)
those that are programmable;ia the front panel push-button key switches, and
2)
those that are programmable via internal switches.
The following areas are programmable from the front panel:
Mass and Time Units: Mass and time units for the flow rate and flow total are pro-
grammable. Available mass units are ounces, pounds, tons, kilograms and metric tons.
Available time units are seconds, minutes and hours.

High and Low Alarms: The high and low alarm levels are programmable for mass

Low flow Cutoff: The amount of "cutoff' applied to the flow rate signal can
lected by the user. The use of a low flow cutoff eliminates unwanted low-level system
noise from the rate and total at zero flow.
Fllter Constant: The amount of filtenna amlied to the mass flow-rate signal is programmable through selection of the filler constant The ab'l'ty to select the filter
constant is part'cularly helplul in noisy or pulsat~ng flow systems.
Frequency Output Parameters (optional): The frequency output generates a freauency Droportional to the mass flow rate. Scaling and sDan parameters are also Pro-

The following are internally programmable:
Meter Type and Meter Factor: The METER TYPE switches allow the FlowScale electronics to be attached to any sensor unit. The METER FACTOR switch is used to
