First, the classification of float level meter

Float level gauge according to the float installed in different locations are also divided into two types of internal and external float, the so-called internal and external division refers to the float installation place, in the measured liquid container is the internal float, in the measured liquid outside the container is called external float.

The inner magnetic float level gauge itself does not have a measuring cylinder, the float is directly installed in the container with liquid, which is mainly used in zero level tanks, underground pools and other environments below the ground. The inner float type level indicator is mounted vertically on top of these vessels through the top flange.

The external float level gauge for tanks itself has a measuring cylinder, the top and bottom of the measuring cylinder are connected to the side of the vessel of the liquid to be measured through the interface flange, forming a liquid level connector, the float is suspended in the center of the measuring cylinder through the top torsion bar and connecting wire.

Second, the structure of the float level meter

Float level meter is mainly composed of the following parts: float, connecting parts (steel wire, fixed card), torque rod, torque sensing transmitter and measuring cylinder (external float) and other table accessories.

Float is a thick-walled metal tube welded at both ends, leaving an interface ring at one end for the upper end of the float.

Connection steel wire is a toughness good sex becomes small stainless steel strip, one end of the connection fixed in the float pull ring, one end fixed in the torsion bar fixed card, the float and the torsion bar connected, is a force of soft conductive components.

The torsion bar is a mechanical torsion arm, connecting the wire by the interaction of gravity and liquid buoyancy of the buoyant force generated by the tension, converted to the axis of rotation around the shaft displacement.

Torsion sensing transmitter on the torsion bar arm of the shaft displacement detection processing conversion, and then with the transmitter internal program parameters for arithmetic comparisons, calculated at this time the height of the liquid level, display and output of standard current signals for remote transmission. Realize the liquid level detection.
