Using this technical scheme：The adjustment that gas flow rate is detected to pressure guiding pipe inside is realized with flow control valve, makes this
Product can adapt to the demand of the liquid level detection to various different denseness waste liquids.
It is further preferred that in above-mentioned waste liquid pool liquid level gauge：Also include pressure-reducing valve, the pressure-reducing valve is installed on air pump and impulse
Depressurized between the input of pipe, to the detection air-flow being pumped into by air pump in pressure guiding pipe.
Using this technical scheme：By operating pressure-reducing valve to enter the pressure value for inputting the detection gas to pressure guiding pipe
Row adjustment, makes the wastewater disposal basin that this product can adapt to different size size carry out liquid level detection.
It may further be preferable that in above-mentioned waste liquid pool liquid level gauge：Also include ball valve, the ball valve is installed on pressure guiding pipe,
Control the ON/OFF of pressure guiding pipe.
Using this technical scheme：Staff can be by operating ball valve to realize shut-off/opening to pressure guiding pipe
Switching, it is to avoid pressure guiding pipe all the time be in normally opened working condition, saved energy consumption, improved the service life of product.
Compared with prior art, the utility model avoids interference of the waste liquid pool bottom sludge to testing result, it is ensured that liquid
The stability of position height detection result, it is to avoid the generation of maloperation.
