The Smith Meter Load Printer is an electro-mechanical, accumulative or zero-start ticket printer that records and prints information received from a pulse-transmitting device, for installations that need a locally printed ticket of each transaction. It works with a Smith Meter AccuLoad or with positive displacement meters equipped with a transmitter / load controller / flow computer providing up to 250 Hz. It takes 10 contact closures per unit volume to advance the right-hand wheel one unit; the electronics drive a stepper motor which drives a standard Veeder-Root mechanical printer head. The operator turns the side handle to lock the ticket and print, and turns it again at the end of the transaction.

How to read the model code
Example: K6LP-XU(Z)-OFW-L. Read the code left to right; each position selects one option:
K6LP (Model designation): Load Printer (K6 is factory reference only and is not shown on the nameplate)
XU (Housing): XU = explosion-proof and UL
(blank) / Z (Printer): Blank = accumulative; Z = zero start
OFW (Hardware options): OP = OPV board; FW = right-hand fixed wheel; LT = long ticket guide; OFW = OPV + fixed wheel; OLT = OPV + long ticket guide; FLT = long ticket guide + fixed wheel; OFL = OPV + long ticket guide + fixed wheel; 000 = none
L (Fixed symbol): Z = zero only; S = litre symbol; L = zero and litre symbol; M = cubic meter symbol; 0 = none (any symbol other than none requires the right-hand fixed wheel option)
How to specify / order
The bulletin asks for the following when ordering:
Complete model number (above), including the fixed-wheel number and/or fixed symbol where used
Units of registration (gallons, liters, barrels, etc.)
Maximum rate of flow
Approval required (UL)
Options: OPV board, right-hand fixed wheel (liter registration in decaliters), long ticket guide
Bulletin notes: the features list says Class I, Group D, Div. 1 while the approvals section says Class I Groups C & D; humidity is printed "5 to 95% with condensation"; standard tickets are given as 7-3/4 in long but the long ticket guide is "for tickets longer than the standard (7.8")"; the example code order (symbol after options) does not match the order of the code table headings. This is a different product from the meter-mounted counter ticket printer (listing SM-TICKET-PRINTER).
