ESMFS 10w/50w Side-mounted 304 stainless steel double float level switch sensor

The stainless steel float switch mainly consists of a float, a float rod, a switch assembly, and a housing. The float is usually made of 316L stainless steel, hollow inside, and can float on the liquid surface. The float rod connects the float to the switch assembly. When the liquid level changes, the float drives the float rod to move up and down, causing the switch assembly to close or open, thereby controlling the circuit connection or disconnection.

The most common control logic for dual float balls is automatic pump control:
Scenario: Automatic water replenishment for the tank.
Low-level float (Low Level): Set as the "pump start point." When the water level falls below this point, the float drops, the contact closes, and the pump starts to add water.
High-level float (High Level): Set as the "pump stop point." When the water level rises above this point, the float rises, the contact opens, and the pump stops to prevent overflow.
Result: Achieves fully automatic, unmanned liquid level maintenance, avoiding frequent pump start-stop cycles (a "dead zone" is formed by the level difference between the two points).

1. Avoid obstacles: If there is a mixer shaft, heating rod, or feed port in the center of the container top, a straight rod cannot be installed. An L-shaped rod can be inserted from the side to bypass obstacles and reach the designated detection area.
2. Edge installation: Suitable for small tanks or narrow spaces, the flange can be installed at the edge corner of the container top, with the rod bent toward the center.
3. Special flow field adaptation: In areas with strong turbulence near the water inlet, the L-shaped arm can extend the float to a calmer area on the liquid surface, reducing false alarms.
4. Bottom drain detection: Certain L-shaped designs can extend the low-level float very low, even close to dead corners at the bottom of the container, ensuring the accuracy of low-level alarms.
