Abstract
A level measuring device for measuring the level of a liquid in a container. The device has an elongated support which extends approximately horizontally into the container and is fastened at a fastening end 6 to a wall 3 of the container while its other resting end 3 rests under initial spring pressure against the bottom 2 of the container. On the support there is fastened a carrier 12 on which a mechanical-electrical transducer is disposed and on which there is pivotally mounted a lever 13 which bears a float 14 and acts on the transducer. The support is developed as an elastic spring in the region between its fastening end 6 and the carrier 12.
Claims11
A level measuring device for measuring the level of the liquid in a container, the device comprising
- an elongated support which extends approximately horizontally into the container and includes a first end and a second end opposite the first end, the support being fastened at its first end to a wall of the container while the second end of the support rests under initial spring pressure against a bottom of the container;
- a carrier fixed to the support between the first and the second ends of the support;
- a mechanical-electrical transducer supported by the carrier and having a lever mounted pivotally to the transducer, there being a float carried by the lever for controlling the transducer;
- and wherein
- the support is formed as an elongated member, the elongated member being bent in the manner of a coil having at least one turn in a region between the carrier and said first end of the support, the coil functioning as an elastic spring;
- and
- a plane of said at least one turn is approximately vertical with respect to a surface of the liquid and parallel to a vertical plane containing said first and said second ends fo the support.
Apparatus operative with liquid in a container, comprising:
- an elongated support which extends within the container and includes a first end and a second end opposite the first end, the support being fastened at its first end to the container, the second end of the support resting under spring pressure against a bottom of the container;
- a carrier fixed to the support between the first and the second ends of the support;
- a mechanical-electrical device operative with the liquid and supported by the carrier;
- wherein the support is formed as an elongated member, the elongated member being bent in the manner of a coil having at least one turn in a region between the carrier and said first end of the support, the coil functioning as an elastic spring;
- and
- a plane of said at least one turn is approximately vertical with respect to a surface of the liquid and parallel to a vertical plane containing said first and said second ends of the support.
