Oscillating liquid level measuring apparatus

摘要

The present invention provides an oscillating liquid level measuring apparatus includes a liquid level measuring unit 10 having: a floating member 3 floating on a surface of liquid 1 in a tank 2; a variable resistor 4 arranged o the top of the tank 2 for measuring a perpendicular displacement of the floating member 3; a transmitting member 5 extending from the floating member 3 and through the top of the tank 2 for transmitting the perpendicular displacement of the floating member 3 to the variable resistor 4; and holders 6 arranged to sandwich the transmitting members 5 for restricting the movement of the floating member 3 only in the perpendicular direction. A connection portion between the transmitting member 5 and the variable resistor 4 has a predetermined allowance 9 in the displacement direction 8 of the floating member 3.
