The most popular float among pump manufacturers!
The BIP STOP float level switch is suitable for CLEAR WATER AND WASTEWATER for automatic pump control.
It is equipped with a simple mechanism and a changeover contact NO/NC (20(8)A- 250V), which signals the liquid level reached in the reservoir of tanks and other containers during filling or drainage, either directly or through a relay.
Thanks to its size and specific shape, the BIP STOP float level switch is a simple, reliable and economical solution used as an essential accessory by pump manufacturers in various industrial and wastewater systems.
Its large differential angle allows it to establish level contact without surges on pump motors and electrical devices in highly agitated liquids. It also detects both high and low levels in the same tank with a hysteresis not exceeding 0.6 m.
With a biconical shape, the copolymer polypropylene float is specially designed to prevent accumulation of impurities on its body, thus preserving its performance and longevity over time.
⚠️ Warning: due to its design, the BIP STOP float level switch is not recommended for slow filling rates. In this case, choose level switches from the AQUA or SOBA range, better suited to this type of application
100% French design and manufacturing.

Drainage or FillingThe BIP STOP float level switch operates on the principle of tilt-based level detection.
The float is equipped with a three-conductor cable (COM, NO, NC), allowing the selection of the operating mode during wiring: Used in pairs with another float of the same type, it allows regulation of the minimum and maximum levels of a tank.
|
In drainage mode, the float level switch activates the pump start in the high position (overflow protection). An electric current passes through the float to the connected device (control relay, pumps, valves, alarms).
Once the tank is empty, the float level switch cuts the electrical circuit to protect the equipment (pumps) in the absence of water in the tank.
In filling mode, the electrical circuit inside the switch closes (NC) when the switch is in the low position. Thus, the pump starts to fill the tank.
Ballast positioningThe triggering of the float level switch (switching angle) may vary depending on liquid agitation, filling/drainage flow rate, but especially on the ballast positioning or fixing point. Indeed, the cable length between the ballast and the float switch determines the amount of liquid that rises or lowers to bring the float switch to change state. You have the possibility to adjust the ballast on the device cable to optimize its operation. |
You have the possibility to adjust the ballast on the device cable, so the greater the distance between the ballast and the float, the greater the level difference will be, consequently the greater the switching angle will be.
This allows the float to adapt to possible turbulence in the liquid but also allows the float to work in a wide range of densities.
Below are indicative values for the BIP STOP with minimum and maximum cable length to ensure proper operation:
Min. value Y = 10cm > X ≈ 30-35 CM
Max. value Y = 30cm > X ≈ 60-65 CM
To adjust the ballast on the cable, simply pull on the plastic or resin ballast to unclip it from the clamping ring or O-ring. Then, slide the clamping ring/O-ring to the desired location and replace the ballast on top, so that the weight is locked on the cable.

Float fixingThe float level switch can be suspended via the cable sheath, using the FIXCAB cable fixing accessory, which allows proper fixing of the electrical cable at the desired height and allows precise adjustment at any time. Beware of using clamps or other elements during fixing that may damage the cable and deteriorate the device by allowing water to enter inside the float level switch by capillarity.
|
Electrical connectionIn outdoor or humid spaces, the electrical connection of the float level switch must be watertight and properly insulated in a hermetic box, thus preventing water or other contaminants from penetrating the cable. This helps prevent water infiltration that could compromise the safety of electrical connections as well as the lifespan of the float. The electrical connection box must never be placed inside the tank. The cable and its capillary can be extended using a standard signal cable. We equip our floats with the cable length you desire to avoid connections that would harm their operation.

Unlike flat sensors, the BIP STOP offers omnidirectional detection. Its shape allows it to react to water movements regardless of its position in the liquid.
This ensures more reliable detection, especially in agitated environments or subject to turbulence.
Fixing accessory strongly recommended for all suspended floats.
Ideal multifunction socket for pump control.
Adjustable ballast is essential for proper float operation.
Level control relay with alarm.
To better define the float level switch suitable for your needs, ATMI offers a wide range of level switches for liquids and solids in various applications.
