HYDRAULIC COMPONENT OVERVIEW
DUAL PHASE PULSERS (STANDARD FLOW)
The 3000 series pulsers are dual phase electronics pulsers that pulse at a rate of 1024 pulses per gallon. These pulsers are physically
mounted to the output shaft of the Bennett SB-100 meter. Note: There is one pulser for every meter. As fuel flows through the meter,
the output shaft rotates and turns the pulser. Approximately 8 rotations of the meter represents 1 gallon of fuel. Refer to the Service &
Troubleshooting section for more information.
SB-100 METER (MECHANICAL OR ELECTRONIC)
The Bennett SB-100 meter is used to measure the flow of fuel in the ‘Standard Flow’ 3000 Dispenser. It is a volumetric meter employing
four pistons with seals and associated chambers. The SB-100 meter maintains a .3% accuracy for flow rates from 1.3GPM (5LPM) to 26
GPM (100 LPM). Note: The SB-100 meter must be calibrated prior to dispenser use. This meter can be ordered with mechanical
calibration or without. If ordered without it, the electronic calibration must be used. Refer to the SB100 Meter Operation, Service, and
Parts Manual for detailed information.
HIGH FLOW METER AND PULSER
The high flow meter and pulser are contained in a single unit and used in the ‘Big Fueler’ dispensers to higher flow rates. This meter /
pulser assembly is electronically calibrated in the field using the E-CAL switch on the 719 CPU board. Refer to the Electronic Calibration
portion of this manual for further details.
