The beneficial effects of the utility model:A kind of liquid level meter connecting device of the present utility model, variable resistance is slided by adding
Device, the slide plate on slide rheostat is driven using the change of water level, so that resistance occurs in the circuit where rheostat
Change, therefore pointer can rotate in instrument board, when pointer rotates to white portion, water level is in Lower state, works as water level
When normal, pointer can rotate to scale zone, and when pointer rotates to black region, siren can sound the alarm, and represent
Water level is higher, has reached the effect for the change that can intuitively reflect water level;
It is connected by concave groove with the gap of glass inside pipe wall, ensures the stability of connecting rod so that is suffered by ball float floating
Power can completely be converted into the pulling force of connecting rod, change rheostatic resistance by slide plate, reach and reduce water level detecting
The effect of error;
By installing waterproof case, prevent liquid from entering damage power supply in power pack, so as to ensure that the normal fortune of circuit
OK, the effect for extending the service life of equipment has been reached.
