Under this function the pulse output of the transmitter can be configured.
Pulse scaling
LOI menu path
Detailed Setup > Output Config > Pulse > Pulse Scaling
Transmitter may be commanded to supply a specified frequency between 1 pulse/ day at
39.37 ft/sec (12 m/s) to 10,000Hz at 1 ft/sec (0.3 m/s).
Note
Line size, special units, and density must be selected prior to configuration of the pulse scaling
factor.
The pulse output scaling equates one transistor switch closure pulse to a selectable
number of volume units. The volume unit used for scaling pulse output is taken from the
numerator of the configured flow units. For example, if gal/min had been chosen when
selecting the flow unit, the volume unit displayed would be gallons.
Note
The pulse output scaling is designed to operate between 0 and 10,000Hz. The minimum conversion
factor value is found by dividing the minimum span (in units of volume per second) by 10,000Hz.
Note
The maximum pulse scaling frequency for transmitters with an intrinsically safe output (output
option code B) is 5000Hz.
When selecting pulse output scaling, the maximum pulse rate is 10,000Hz. With the 110
percent over range capability, the absolute limit is 11,000Hz. For example, if you want the
transmitter to pulse every time 0.01 gallons pass through the sensor, and the flow rate is
10,000 gal/min, you will exceed the 10,000Hz full-scale limit:
