DESCRIPTION 
The electronic register module contains a microprocessor 
board powered by a lithium battery. It can be programmed 
to measure in liters, pints, quarts, or gallons. A calibration 
factor and unit of measure are programmed during factory 
test. Unlike mechanical registers, these units can be 
electronically recalibrated in the field when necessary. A 6-
digit LC display, accurate to three decimal places, shows the 
exact amount of fluid that has passed through the meter. The 
entire register module is protected from normal wear and 
tear by a rugged, shock resistant housing. 
OPERATION 
Industrial oval gear meters and nutating disc meters have 
rotating magnets that cause the reed switches to send pulses 
to the register when fluid passes the meter.  
The register is in a sleep mode until it detects these pulses 
caused by fluid going through the meter. The micro-
processor in the register then measures the flow and will 
display the totalization and the flow rate of the fluid going 
through the meter on the 6-digit display. 
The registers batch totalizer is a 6-digit display with three 
places of resolution after the decimal point. 
If the total dispensed exceeds 999.999 then the display will 
shift and only 2 digits will be displayed after the decimal 
point, 9999.99 and will continue to shift to the maximum 
value of 999999. 
After reaching 999999 the batch totalizer will rollover to 
0.000. The batch totalizer is reset to zero when the reset 
button is depressed. 
The register also has a resettable totalizer that requires that 
the total and reset button both be depressed to reset (hold 
the “Total” button, then press the “Reset” button to reset this 
totalizer while resettable totalize is displayed). This would be 
used for multiple batch totalization purposes. 
The register´s life time totalizer is 11 digits and will either be 
in gallons or liters based on the unit of measure selected. 
Pushing and holding the total button while the life time 
totalizer is displayed will display the full 11-digit life time 
totalizer value.
