The tank body is made of translucent plastic, which allows you to visually control the liquid level.
A cover 9 is screwed onto the filler neck of the tank, which presses the housing 7 of the terminal device and the reflector 3 to the end of the neck. A device for monitoring the liquid level in the tank is mounted in the housing 4. It consists of a float 1, on the rod 2 of which a movable contact 6 is located, and a fixed contact 5, fixed in a plastic housing 4.
When the liquid level drops, the float drops, the contacts close the circuit of the control lamp, which lights up with a constant light.
In the central opening of the housing 7 of the terminal device, a pusher 8 is installed, when pressed, the operability of the control lamp circuit is checked at a full liquid level in the tank. In the housing 7, two terminals are made for connecting wires to them.
