Product Description

Product Description

A threaded-in type float level sensor is a popular solution for measuring fluid levels in tanks and reservoirs. This design features a float that moves with the liquid level, and it is mounted through a threaded connection, providing a secure and reliable installation. Here's an overview of its key aspects:

Key Features:

1. Threaded Design: The sensor screws directly into the tank, providing a robust and leak-proof connection.

2. Float Mechanism: The float rises and falls with the fluid level, activating a switch (typically a reed switch) to signal when certain levels are reached.

3. Material Options: Available in various materials (such as stainless steel or PVC) to suit different liquids and environmental conditions.

4. Customization: Can be tailored for different float sizes, lengths, and switch configurations to meet specific application requirements.

5. Easy Installation: The threaded connection simplifies installation and maintenance.

Applications:

• Water Tanks: Used for monitoring water levels in municipal, agricultural, or industrial applications.

• Fuel Tanks: Commonly employed in automotive and marine industries for accurate fuel level monitoring.

• Chemical Storage: Suitable for various chemicals, depending on the material used for the sensor.

liquid level sensors and switches provide high
reliability monitoring and detection of a wide range of fluid media and applications anywhere from medical reagent level monitoring, to sensing of liquids in food and beverage applications, to hydraulic fluids, to diesel fuel tanks (gas level indicator), to water and wastewater, deionized or potable water, and hundreds more.

What can we do?

We offers a wide variety of standard, vertical, and horizontal liquid level float switches. Standard float switches are available in stainless steel, and plastics, including PVC, polypropylene, or PVDF. Liquid level float switches are used to maintain a safe level of fluid within a tank or container. They can assist even more efficiently by automating the dispensing of liquids, whether into or out of the tank to maintain the optimal level, and can be connected to an alarm to sound when the optimal level is not met. With the ability to customize the length, they can even be used to control the filling of all types and sizes of vessels from small to large tanks.
These versatile liquid level float switches are typically hard mounted into the tank wall or extend further into the tank using extension tubes and liquid tight tube fittings.

How does it works?

Most of our vertical liquid level indicators can be changed from normally open to normally closed by simply removing the retainer and flipping the float. When the level switch is in the normally open mode, it is OFF until the float is lifted by the liquid and makes contact with the elastic ring, turning the switch to the ON position. When the switch is on, which allows for the tank to be automatically start emptying the tank until the switch turns back off, which then would tell the system to start filling the tank. This ensures that the tank level never gets too low. The applications for this simple switch are endless.

Vertical

Vertical float level sensors can be mounted in the top or the bottom of the tank. This gives the ability to have two points of contact, creating a system of emptying and filling the tank as efficiently as possible with minimal down time. The vertical float level switches have various mounting threads and can be made from stainless steel, and plastics for your budget and needs.

Horizontal

Horizontal float type level switches mount on the side of the tank. This lets you have the ability to set the exact level you would like regardless of the size or shape of the tank. With various mounting threads and materials available, we can design the perfect solution for your problem.
