Abstract
Meters are described. In one example, a meter includes a totalizer including an electronic circuit and a metering screen, a cap at least partially covering the totalizer, the cap including a window to facilitate viewing of data of the metering screen, and a screen cover mounted on the cap and movable between an open position and a closed position in order to cover the metering screen. In such an arrangement the electronic circuit includes a device for detection of the open position or the closed position of the screen cover, and the detection of the open position or the closed position controls scrolling of data of the metering screen.
Claims21
A meter comprising:
- a totalizer comprising an electronic circuit and a metering screen;
- a cap at least partially covering the totalizer, the cap comprising a window to facilitate viewing of data of the metering screen;
- and
- a screen cover being mounted on the cap and movable between an open position and a closed position in order to cover the metering screen, wherein the electronic circuit comprises a sensor to detect a magnet for determination of the open position or the closed position of the screen cover, and wherein the determination of the open position or the closed position controls scrolling of data of the metering screen, wherein determination of a number of successive closures of the screen cover defines a context to select a parameter corresponding to the number of successive closures, the parameter to be displayed on the metering screen, and wherein the magnet is over-molded into a protrusion of the screen cover that extends from an inner surface of the screen cover.
The meter of 12, wherein a perimeter of the perimeter protrusion follows an outer perimeter of the screen cover.
A meter comprising:
- electronics including a sensor and a metering screen;
- and
- a screen cover movable between an open position and a closed position in order to cover the metering screen, wherein the sensor detects a magnet to determine whether the screen cover is in the open position or the closed position, and wherein the determination of the open position or the closed position controls scrolling of data of the metering screen, wherein determination of a number of successive closures of the screen cover defines a context to select a parameter corresponding to the number of successive closures, the parameter to be displayed on the metering screen, wherein the magnet is over-molded into a protrusion of the screen cover, the protrusion extending from an inner surface of the screen cover.
A method for use in a meter, the method comprising:
- displaying a first data item on a metering screen;
- determining, via detection of a magnet by a sensor, that a screen cover associated with the metering screen has changed position between an opened position in which the metering screen is visible and a closed position in which the metering screen is not visible, wherein the magnet is over-molded into a protrusion of the screen cover, the protrusion extending from an inner surface of the screen cover;
- selecting a second data item based on a number of successive closures of the screen cover, wherein the number of successive closures defines a context to select a parameter to be displayed as the second data item;
- and
- displaying the second data item on the metering screen in response to detecting that the screen cover over the metering screen has changed position.
