General
A pulser is an optional device which is used when external monitoring of the dispensing unit
operation is desired. The pulser transmits one electrical signal (pulse) for each predetermined
amount of fuel dispensed. The signal is received by the external monitor (fuel management
system) which keeps a running total of the quantity of fuel being dispensed during each
transaction.
All of the pulsers in the Series 9120Q are operated with DC voltages. These pulsers include the
reed pulser which outputs 10 pulses per unit of measure and the electronic pulsers which are
available at 100 pulses per unit of measure. The pulser type should be selected according to the
monitoring equipment, the application, and the regulations that must be met.
Refer to the wiring diagrams in the previous section for pulser wiring.
