Specifications:
Both the CUENTA METROS Model 7M and Model 7ME feature a 7-digit display with digits measuring 8 mm in height. They have an approximate maximum counting rate of 500 meters per minute. The counters are equipped with a zero reset function using a key-lock combination. The impulse shaft is present on both sides, allowing for counting adjustments based on the direction of rotation, either adding or subtracting.

Model 7M:
This model is specifically designed with a counting ratio of 2 turns equaling 1 meter. Customers need to specify the required direction of rotation and whether an aluminium pulley or a rubber puller is needed when placing an order.

Model 7ME:
This model is tailored for measuring materials such as cloth, ribbon, and wire in reels.

Additional Information:
The document includes diagrams illustrating the direction of rotation and its impact on counting (adding or subtracting) in different positions. The contact information for TALLERES EMIT, S.A., the manufacturer, is provided for further inquiries.
