| PURPOSE: To correct and display the amount of fuel in a subtank by providing a main tank part with a liquid level detecting mechanism having a variable resistor associated with a float, providing the subtank part with a liquid level detecting element, and finding the composite resistance of the resistance of the liquid level detecting mechanism and the resistance of the liquid level detecting element. CONSTITUTION: When the fuel in a tank main body 1 is consumed and the main tank part 3 and subtank part 4 need to be filled with fuel, an exector 7 sends the fuel in the tank 4 to the tank part 3. When the fuel in the tank 4 decreases exceeding a lower limit, the fuel in the tank part 3 is consumed to decrease below the highest level. The sequential variation in the amount of the fuel is displayed on a meter 21 based on the composite resistance R 5 of the resistance R 3 of the liquid level detecting mechanism 13 equipped with the variable resistor 16 associated with the float 15 and the resistances R 1 and R 2 of thermistors 19 and 20 which constitute the liquid level detecting element provided in the tank part 3 and have negative resistance temperature coefficients.

| PURPOSE:To detect and display the remaining quantity of fuel in a tank by a simple constitution even when a vehicle is tilted or accelerated or decelerated, by connecting a liquid level displacement signal, which is held in a holding circuit to a display means, when a slant detecting sensor detects the slant liquid surface. CONSTITUTION:When a body is kept horizontal, a flexible film 63 is deflected by the weight of a spherical body 62 and a switch 64 is closed. Then the remaining quantity of fuel that is shown by a float 3 is outputted as an electric signal from a potentiometer 4. The output is stored in a capacitor C and connected to a meter 5 through an amplifier AMP. When the body is inclined or the liquid surface of the fuel is inclined by acceleration or deceleration, a cabinet 61 of a slant detecting sensor 6 is inclined, and the spherical body 62 is moved from the upper part of the flexible film 63. Therefore, deflection of the flexible film 63 is returned to the original state and the switch 64 is opened. Then the output from a potentiometer 4 is cut OFF. A liquid level signal in the potentiometer, which is held in the capacitor immediately before, is outputted to the meter 5 through the amplfier AMP. | ||||||

| PURPOSE:To early detect an oil leak accident, by emitting an alarm on the basis of the detection of an oil level difference of an oil supply tank of each of the three phases of oil-filled cable. CONSTITUTION:Three guide pipes 10 made of non-magnetic material are arranged virtually in the shape of a equilateral triangle corresponding to single- core OF cables, and a main magnet 11 is incorporated in each pipe. The three guide pipes 10 are inserted through a floating body 12 having a hollow part shaped virtually in an equilateral triangle. Around the hollow part 13, a number of magnets 14 are arranged in the direction in which they are repellent to the main magnet 11. When the floating body 12 lowers, a movable supporting table 15 contacting therewith is fixed, and further a mercury switch 16 is fixed thereon. If an oil leak occurs in the OF cables of one or two phases or oil supply tanks, a level difference is caused, and thereby the floating body 12 is inclined. When the repellent force of any one of the main magnets 11 is decreased due to the lowering of the level, the floating body 12 drops. Then the mercury switch 16 is inclined by the weight of the floating body, and thereby an alarming circuit is connected to emit an alarm. | ||||||

| PURPOSE:To prevent an overflow accident while shortening intervals of monitoring for tanks wherein the amounts of liquid vary abruptly by selecting an optional tank and making intervals of measurement of the liquid level of the tank shorter than that of any other tanks. CONSTITUTION:When a switch A among tank specifying switches 7 is operated to supply oil liquid from a tank truck A to, for example, a tank A among tanks A-F, a switch control circuit 8 sends such a driving signal to the driver 4 of a sensor selection switch 2 that while a switch 3A is closed at every other time, switches 3B-3D are closed successively in other turns until one round is made. A liquid level sensor 1A sends a liquid-level detection signal to an arithmetic circuit 5 at a period a half as long as those of other liquid level sensors 1B-1F, and a display part 6 displays the measured amounts of liquid correspoinding to respective periods. When the switch G is operated for normal operation, the measured among of liquid of the tanks A-F are displayed at the same period. Therefore, even if the amount of liquid in one tank varues abruptly, an overflow accident is prevented. | ||||||

| PURPOSE:To detect the phase difference between both vibrations by sampling the amplitude value of the vibration produced by arising from a known frequency. CONSTITUTION:A detector 17 which detects the vibration of a mold 2 and a detector 16 which detects the molten metal level in the mold 2 are provided in a continuous casting plant. When the mold 2 makes simple vibration of a frequency omega (known), the signal of (equation-1) appears in the output of the detector 17. Also, the signal of (equation-2) (alpha: phase angle) appears in the output of the detector for the molten level vibrating along with the mold. These outputs are sampled at the times t1, t2, t3, and (equation-3) is obtained, by which the phase angle alpha is determined. Simultaneously, wave crest a0, y-intercept b are determined as well. In this way, the phase angle alpha is measured accurately dispite the existence of time lag of first order in the response of the molten level detector. Hence, the molten metal level in the mold is accurately maintained. | ||||||
