The present invention is to measure the flow rate by installing in an oil tank such as a hot air heater or a boiler for oil, and the movable plate linked with the float detects the fixed resistance value by moving the float in the oil tank up and down according to the flow rate. By sending this to digital or L, E, D lamps and other indicators, this fixed resistance value is converted to a numerical value or lit by L, E, D. The flow sensor that has been used has been designed to mechanically connect and rotate the shaft with the indicator needle by means of the ball, so that the indicator needle can be rotated as the ball attached to the shaft moves up and down. Several types of flow detectors are known, but they are far from the oil tank because they have to be attached directly to the oil tank. It was not possible to measure the flow rate from the outside, so in order to measure the flow, there was a hassle that the measurer had to go to the oil tank and check it. It was.

In view of these problems, the movable plate is rotated according to the up and down movement between the operation with the float, and the variable board is fixed by the fixed contact piece connected to the movable contact piece on the movable plate. By detecting the resistance value and sending it to the display unit, the flow rate value is converted into L, E. D lamps, etc., but this is sensed by detecting the variable resistance value that changes according to the position where the movable contact piece is connected on one fixed contact piece It was difficult to measure the exact value of the flow rate because it was supposed to measure the flow rate value.

The present invention has been devised in view of the above problems, and it is possible to fix a plurality of fixed contact pieces on the engine so as to be separated from each other, and to connect each fixed contact piece with a fixed resistance having a predetermined value of resistance. When the contact piece is connected, the specific resistance value is transmitted to the display unit to measure the accurate flow rate, and to make it easy to measure the flow rate at any place other than the oil tank installation place. When described in detail based on the accompanying drawings as follows.

According to the present invention, the flow sensor 5 having the detector mounting portion 3 integrally formed under the support 1 having the stoppers 2 and 2 'formed on the upper and lower sides thereof, and the opening 4 being attached to one end thereof. The rotating shaft 6 is rotated in accordance with the flow of the flow interval 5 by being fixed to the rotating shaft 6 of the detector mounting portion 3, and a plurality of fixed contact pieces on the upper surface of the detector mounting portion 3 ( 7) are fixed so as to be separated from each other, and each fixed contact point piece 7 is formed with a substrate 8 connected with fixed resistors 7 'each having a constant resistance value, and is fixedly installed about the rotational axis 6. However, the movable plate 9 having the movable contact piece 9 'connected to the fixed contact piece 7 on the substrate 8 fixed thereto is inserted into the rotating shaft 6 and rotated according to the rotation of the rotating shaft 6. While rotating, the fixed resistance value of the fixed contact piece 7 connected to the movable contact piece 9 'is sensed, and the power line 11 is connected to the terminal 10 of the upper end of the support 1 to connect the digital or L , E, D lamps It is configured to display the flow rate value by transmitting the detection result to the time portion 12, reference numeral 13 is an oil tank, 14 is a fixed flange.

Referring to the operation and effect of the present invention having the above configuration as follows.

When the present invention flow rate detection device is installed in an oil tank 13 such as an oil heater, a warm air heater or a boiler, the float 4 moves up and down according to the flow rate in the oil tank 13, and accordingly the float 4 is When the attached rotating shaft 5 flows and the rotating shaft 6 in which the flowing shaft 5 is condensed rotates, the movable plate 9 inserted and fixed to the rotating shaft 6 rotates in the same direction and then stops. The movable contact piece 9 'on the movable plate 9 is connected to one of a plurality of fixed contact pieces 7 which are separated from each other and fixed on the substrate 8, and thus the fixed resistance of the fixed contact piece 7 is fixed. By detecting the value and transmitting it to the display unit 12, the flow rate value is converted into L, E, D lamps or digital numbers. The outline of such a circuit process indicates that the movable plate 9 depends on the level at which the mouth 4 is located. The fixed resistance value of the fixed contact piece 7 to which the movable contact piece 9 'of the phase is connected is transmitted to a known computing device, and The device detects and calculates the changing potential and applies its output to the corresponding L, E, D to light it up. The display is connected to the display circuit by L, E, D, or digital display by segment. In this case, the plurality of fixed resistors 7 'fixed on the substrate convert the electric potential to adjust the input signal so that the measurer can read the flow value on the indicator, such as digital, L, E, and D lamps. The indicator makes it possible to measure the flow rate in places other than the oil tank installation place, as well as to accurately measure the flow rate in the oil tank with less troubles than conventional mechanical oils. It is an advantageous design that can be easily mounted and used on the tank.
