Abstract

A device for periodic, automatic, readable recording of a meter value from a consumption measuring meter including a casing attachable to an otherwise conventional meter and provided with a slot, a printing unit disposed within the casing and located out of the plane of the slot in order to be tamper-proof, the printing unit being composed of an identification data printer and a consumption value printer and being adapted upon insertion of a record card in the slot of the casing to apply to the record card a visually readable marking of the identification data and meter consumption value, and a push button connected to the printing unit and manually actuable for causing the marking to be applied to the record card by shifting the printing unit towards the record card inserted into the casing through the slot.

Claims

1. A device for periodic, automatic, readable recording of a meter value from a consumption measuring meter comprising:

a casing attachable to an otherwise conventional meter and provided with a slot;

a printing unit disposed within said casing and located out of the plane of said slot in order to be tamper-proof, said printing unit being composed of an identification data printer and a consumption value printer and being adapted upon insertion of a record card in the slot of the casing to apply to the record card a visually readable marking of the identification data and meter consumption value; and

a push button connected to said printing unit and manually actuable for causing said marking to be applied to the record card by shifting said printing unit towards the record card inserted into the casing through said slot.

2. The device as claimed in claim 1 for measuring consumption of a medium other than electricity the meter being driven by and measuring the number of consumption units of a flowing medium which is caused to pass through a conventional metering unit wherein said casing is screwed onto the unit.

3. The device as claimed in claim 2 wherein the metering unit is a meter of volume-metering type and further comprising an adapting ring and a mounting ring mounting said casing on said adapting ring.

4. The device as claimed in claim 2 wherein said consumption value printer comprises a number of counter elements and said identification data printer comprises several individually adjustable and subsequently lockable number wheels for adapting the identification code of the individual meter to existing codes, and a record card inserted through the inserting slot can have applied thereto, in addition to the identification code, also a record of the actual positions of the individual counter elements.

5. The device as claimed in claim 1 wherein the identification data and consumption values are provided side-by-side for application to the record card at predetermined locations situated side-by-side.

6. The device as claimed in claim 1 wherein the identification data and consumption values are arranged in line with each other for application to the record card at locations provided in line above each other.

7. The device as claimed in claim 1 wherein said printing unit is adapted to apply to the record card a marking which is also optically readable.

8. The device as claimed in claim 1 for use with a record card in the form of a postcard.

9. The device as claimed in claim 3 wherein the metering unit is a water meter.
