Float Switches

Float switches are used to detect liquid level in tanks, vessels, or containers. Float type level switches are used many different applications to indicate high or low level conditions, control pumps or valves, and provide indication. These simple devices are critical to hundreds of different applications. When the liquid level reaches the float, the float raises up and trips the internal reed switch to make a connection.

Liquid Level Indicators

Liquid level indicators are used in tanks, vessels, and containers to provide clear indication of the exact liquid level. These sensors utilize floats switches, sophisticated ultrasonics, and pressure to sense the liquid level. Easy to read displays with LED lights or digital readouts provide clear indication of the exact level. The displays indicate if the tank is full or empty and with optional relay outputs can also signal high or low level alarms.

Temperature Level Sensors

Many applications require the ability to maintain a certain temperature or alert users of a high or low temperature condition. This can be done by using a temperature sensing device. These sensors can protect heaters and other equipment as well as maintain safety. Three of the most common devices are Thermostats, Thermocouples, and Thermistors. These devices can be used on their own or in conjunction with a float switch to combine level and temperature sensing into one convenient product.

Alarms and Accessories

We have an extensive line of accessories and key components that are essential to providing a complete solution for any liquid level application. Our liquid level & temperature sensing product accessories include audible and visual alarms , junction boxes, relays, and digital panel meters. We also offer many components, fittings, adapters, switches, and tubing.

Float Switches

Standard Single Level

We offer a wide variety of vertical, and horizontal liquid level float switches. They are available in stainless steel, brass & buna or  plastics, including PVC, polypropylene or PTFE. These versatile switches are a great choice for high and low level alarms or control switching. There are many different threaded mounting options, SPST and SPDT reed switch choices, and longer length lead wires. These economical single point floats are a great choice for OEM’s and are often in stock and quick to ship.

Custom Multi Level

we specialize in made to order Multi level liquid level float switches. Tell us your application and we will make a sensor to your specifications. These sensors are ideal for monitoring multiple switch points, controlling pumps & valves, warning of high or low level alarms, and indicating tank levels. These versatile level switches are available in Stainless Steel, Brass & Buna, PVC, Polypropylene or PTFE. Our engineers will work closely with you to spec out the exact made-to-order liquid level float switch for your application needs

Field Assembled

Field assembled float switches are a great choice if you need to customize a sensor in the field or you need it fast and cannot wait for a custom made to order float. The complete kits come with everything needed for a two level sensor. If you require more than two levels additional fittings and switch points can be purchased separately. These versatile float switches are available in brass & buna or stainless steel  and are a good choice for many different sensor applications.

Speciality Sensors

We offer a variety of specialty liquid level sensors including low water conductive and sump pump style float switches. Our Specialty floats are made for difficult or demanding sensor applications such as high temperatures, thick or sticky liquids, high turbulence, or difficult mounting. These sensors can be customized and are available in a variety of materials. When a traditional float type level switch doesn’t meet your needs see if one of our specialty floats will.

Level Indicators

Mechanical – LLTM series

These liquid level sensors are fully mechanical and provide an exact measurement of how much liquid is in your tank. These units are ideal for portable storage tanks, hazardous locations, or remote areas where electricity is not available. They are offered in stainless steel, brass & buna, and polypropylene. To take a reading simply pull the tape measure out of the stem until you feel a magnetic lock up.

Continuous Level – CLM Series

These vertical float type continuous level sensors are used in tanks and vessels that require precise liquid level indication. They are offered in Stainless steel, Brass & Buna, or polypropylene. The sensor is a 3 wire potentiometer that provides a change in resistance every ¼” of level movement. Use a digital panel meter to display the exact liquid level reading or signal conditioner which provides a standard 4-20mA output signal.

Multi Point – LKI series

These multi point level sensors are a great choice for storage tanks and totes. They provide bright, easy to read, full to empty LED indication. These versatile float switches are available in stainless steel, brass & buna, and polypropylene. Additional output relays can be added for high and low alarms or pump control.

Ultrasonic – ULS series

These non contact ultrasonic distance sensors provide highly accurate level indication and can measure lengths up to 30 feet. They are great for tank farms and large outdoor storage tanks. They can be used to detect liquids or solids and come with various sensor output options.



We offer a wide variety of audible and visual alarms. These alarms are often used in tanks to provide clear warnings of high or low tank level conditions. They are wall mountable and come in various voltages. Custom configurations are available to suit your specific application.


We offer a variety of relays which can be used to control pumps, valves, and alarms. Our dual level control relay adds the ability to maintain and control tank levels for filling and draining applications. Use mechanical power transfer relays to take the load of high voltage or current devices such as pumps and heaters.

Junction Boxes

Junction boxes provide a convenient location for connecting wires. They provide protection from the environment, have standard process openings, and are available with terminals. Our aluminum junction box is rated for hazardous locations and is class1 Div1 approved.

Meters & Signal Conditioners

Digital panel meters and displays are used with our continuous level floats and ultrasonic distance sensors. They give a numeric indication of the exact level in your tank and are available with optional relay, voltage, and current outputs.


We offer raw materials, fittings, tube, floats, and many other individual components that we use to make our float switches and sensors. If you need a replacement part, something is lost or damaged, or you just want to make your own product, we have what you need.

Temperature Sensors

Temperature Level Switch

Temperature level float switches provide the ability to incorporate temperature sensing and liquid level detection into one convenient sensor. The temperature sensing device is a bi-metallic thermostat that is designed as general protection for heaters or to warn of high or low temperature conditions, they are not intended to act as precision temperature indicators. Both temperature and float level can be ordered either normally open or normally closed.

Thermowell Sensor

Thermal Well Switches are designed to indicate temperature only. These small probes can fit into almost any size tank. The most common temperature sensing devices are thermostats, thermistors, thermocouples, and RTD’s. Bi-Metallic thermostats provide a gross high or low temp cut off or warning. The thermistors, thermocouples, and RTD’s are high precision sensing elements that give very accurate readings of the exact temperature of the liquid.
