Has displacement transducer in the shell, displacement transducer, shaft collar, carriage, stroke lever, gag lever post, lead.Two shaft collars are fixed on the outer casing inner wall with screw respectively, carriage is fixed on the inwall, displacement transducer places on the carriage, displacement transducer middle and lower part and shaft collar screw are fixed, its top withstands on another group shaft collar, displacement transducer upper end lead is connected conducting with displacement transducer, and the displacement transducer lead-out terminal is connected with binding post by lead, and binding post is connected with metering house or computing machine.Has stroke lever in the displacement transducer cover bucket.Gag lever post passes the hole on the shaft collar, and fixing button is screwed in the gag lever post top with screw.

Benefit of the present utility model is:

1, the utility model adopts the uncovered sample bucket of the no end that stainless steel is made, be installed in the fluid to be measured, tested main body is separated with keg float and is connected, can reduce liquid fluctuating, reduce the foam viscous mass and ring measuring face, more accurate detection liquid level, degree of accuracy is 3/1000ths, and can import the 0-20mA signal, have versatility.

2, the utility model adopts bicone cylinder keg float, has solved the resistance of foam viscous mass.

3, in bicone cylinder keg float, have counterweight, increased keg float weight, bicone cylinder keg float is immersed in the ore pulp, can overcome the continuous variation of foam buoyancy and froth bed, accurately measure the ore pulp height.

4, adopt the design of anti-water seal owing to shell, displacement transducer, displacement transducer, solved the problem of liquid evaporation water vapor, prolonged the serviceable life of detecting device.

5, rational in infrastructure, the simple installation of the utility model, durable, corrosion resistivity is strong.Keg float adopts stainless steel to make, and can realize the robotization of flotation machine liquid level, remedies the blank of flotation machine equipment, has very high promotional value.
