MECHANICAL METER REGISTER

The 7887 Mechanical Meter Register is used to register the volume of any liquid fluid, allowing stock (inventory) and dispensing transactions control.

Utilizing a geared drive available in a wide selection of ratios, this equipment records in practically any unit of liquid measure, such as liters, decalitres, gallons and barrels.

Special adaptors are available to mate the Mechanical Meter Register with any volume meter register available in the market.

Optionally, the Mechanical Meter Register can be connected to other modules, what makes it even more functional for data control and delivery, according to the models below:

• Model 7890 = 7887 Mechanical Meter Register with Printer 7888
• Model 7891 = 7887 Mechanical Meter Register with Preset 7889
• Model 7892 = 7887 Mechanical Meter Register with Printer 7888 and Preset 7889

The 7888 Printer enables printing of data recorded by the 7887 Mechanical Meter Register for documentation. There are two printer models, the Cumulative and Zero Start.

The Cumulative Printer first prints the cumulative total of the previous dispensing transaction and then the grand total adding the new dispensing transaction. The quantity of delivered liquid is calculated by subtracting the previous total from the final total.

The Zero Start printer resets any previously accumulated value before printing. Therefore, the total printed after the liquid delivery is the actual quantity of the transaction, without the need for making calculations.

The 7889 Preset is used to predetermine the quantity of liquid fluid to be delivered. The presetting is easily programmed manually on the equipment keypad.
