All Sensor Float models are rated 13 amps (120V A.C. or 230V A.C.). Both the heavy-duty, mercury activated tilt switch and the cord conductors are epoxy sealed in a watertight, impact resistant float housing. The mercury tilt switch activates when the float is a few degrees above or below the horizontal position.

Sensor floats may be used to activate pump control panels, solenoids, and relays. This liquid level control is frequently used in sewage systems, irrigation systems, and in other water systems.  Sensor floats are used most often in multi-pump applications and in Capsule Pump Stations.

PC (Pipe Clamp) Model: The PC is not weighted and is installed by strapping the pipe clamp at the desired activation level to a discharge pipe or other similar mounting.

Cable Weight Model: The float is used with an optional cable weight so that the switch can be suspended from above.

NORMALLY OPEN (Pump down) application: The mercury float switch closes (turns on) when the float tips a few degrees above the horizontal position and opens (turns off) when the float drops a few degrees below the horizontal position.

NORMALLY CLOSED (Pump up) application: The mercury float switch closes (turns on) when the float drops a few degrees below the horizontal position and opens (turns off) when the float tips a few degrees above the horizontal position.

Cable weights may be used with sensor floats to weigh down the float as opposed to using a pipe clamp to attach the float to a float pole. Note: use cable weights whenever turbulence maybe an issue. These weights help keep the floats from getting tangled together when not firmly attached to a float pole. These float weights are optional and are not required for normal operations.

Allows for accurate operation of float switches.

Gripper teeth on the clip and weight channel securely lock the float cable into place.

Location of the cable weight can be modified by removing the clip and repositioning the cable in the weight channel. No tools are needed.

A float pole is constructed of 1-1/2" PVC pipe mounted inside of a 2" steel pipe stub that is welded to the bottom of the capsule tank. The floats are attached to a length of 2" PVC pipe that is slipped over the 1-1/2" PVC pipe. The 2" pipe has a handle at the top that allows the operator to pull the floats up and out of the capsule pump station or pit without removing them from the pole itself.

When ordering a float pole for your application, please specify the length (height) for the float pole. Poles are available in lengths up to 20'. And can be ordered separately or in a capsule pump station.

Cable connectors provide strain relief and a liquid-tight seal. Simply insert the cable through the center hole and screw down the sealing nut. The cable is held in position, centered, strain relieved, and automatically adjusted to the size of the cable. Recommended for use with control panels, float switches and applications where a liquid-tight seal is required.

Cable connectors are also used on strainer screens to provide a tight seal around the motor lead and prevent debris from entering the screen through an access hole.

The control relays and electrodes can be used as an alternative to float switches. This liquid level control requires the use of a relay wired into the single or three phase control panel, an electrode holder and electrodes suspended in the wet well.

In the B & W system of float-less liquid level control, electrodes or probes are suspended in the wet well to make contact with the liquid and thus complete a circuit which actuates a B & W relay. The relay contacts in turn are used for a wide range of applications such as controlling pumps or sounding alarms for off normal level conditions.

Electrodes are normally used with a suitable holder and wherever possible, should be suspended vertically downward from the top of the tank containing the liquid. Also, electrodes are connected to the sensing circuit of a B & W relay. While this is a low energy circuit with inherently limited low current, the electrodes are terminals of a live electrical circuit and must be installed to prevent contact by unauthorized personnel. This system is not recommended for use in applications where there is the possibility of contact by humans or animals, as electrical shock may occur.

A B & W float less liquid level control system consists of a relay of the proper type, a holder designed to support one or more electrodes or probes in the wet well and the corrosion resistant electrodes themselves.

The B & W 1500 induction relay utilizes the liquid as an electrical conductor to complete the secondary circuit between the electrodes. Thus when the liquid contacts the upper electrode, the resulting flow of current in this circuit pulls the armature into contact with the legs, as shown in Figure 2. This armature movement closes the electrode and load contacts.

The lower contacts on 1500-C Relays (terminals 9 and 10) connect the secondary circuit to ground when liquid contacts the upper electrode and act as a holding circuit to maintain the relay in its closed position until the liquid falls below the lower electrode. This holding circuit provides control of the relay over any desired range in the liquid level, depending on the distance between the upper and lower electrodes.

B & W electrodes are available in four different styles. These electrodes are installed in the wet well using an electrode holder. Each application requires the use of one electrode each for pump on, pump off and ground. For example, a single pump application would require three electrodes; a two pump application would require a minimum of four electrodes - lead on, lag on, common off and ground; etc. These electrodes can also be used to indicate high or low water level conditions.

Type E-1P-Shielded: This electrode is approximately 4" long and assembled in a molded plastic insulating shield 1-7/16" in diameter. Designed for general purpose use, it is ideal for elevated tanks, pumping stations and deep well installations. This electrode is available in either brass or 303 stainless steel.

Type E-1S-Shielded: This is a 2" long electrode assembled in a molded plastic shield 9/16" in diameter. It is ideal for use in submersible pump installations and other applications where little clearance is provided for installation. This electrode is available in either brass or 303 stainless steel.

In general, B & W electrode holders have a mounting provision to mate with standard pipe fittings on the tank. These holders have watertight protection for the conduit or cable entrance. Where possible, all electrodes should be grouped into a single holder and mounted on top of the tank with the electrodes extending vertically downward. The holders are available for the mounting of up to 7 electrodes and accommodate between 1" and 3" pipe mounting threads. Each holder includes the electrode plugs necessary for attaching the Type SW suspension wire to the holder.
