Level Switches: Reliable Automation for Industrial Safety

​Flowtel Engineering provides high performance level switches designed for the critical detection of liquids and solids in industrial processing. Unlike continuous measurement tools, these switches function as automated triggers that manage pump operations and alarm systems once a specific material height is detected. This functionality is the primary defense against tank overflows and equipment damage caused by dry running conditions.

​Our engineering team focuses on building level switches that maintain accuracy in the most challenging environments. Whether your facility manages high pressure steam, corrosive acids, or turbulent liquids, our switches are built to endure. We offer various technologies including magnetic and float operated designs that integrate easily into existing control systems. At Flowtel Engineering, we prioritize long term reliability and precision, ensuring that your automation remains consistent and your facility stays safe from operational errors.

Displacer Type Level Switches

Displacer Type Level Switches

Level Switches

Flowtel Engineering manufactures high quality Displacer Type Level Switches based on the buoyancy principle for precise liquid level control. These switches are specifically designed for underground and overhead tanks, providing a reliable solution for monitoring water, furnace oil, chemicals, and effluents. The magnetic coupler design ensures a leak proof seal between the process and the switch. With a pressure capacity of 20kg per cm² and temperature resistance up to 150°C, these switches perform consistently in tough industrial environments. They offer flexible actuation points like HI and LO, which can be adjusted over the entire stem length to suit your specific tank requirements.

RF Level Switches

RF Level Switches

Level Switches

Flowtel Engineering provides the FLRF 20 Series RF Level Switches, designed for high reliability across diverse material types. Operating on the Radio Frequency (RF) principle, these sensors are effective for conductive or nonconductive media, including granular solids, slurries, and pure liquids. The system uses a sophisticated electronic controller that generates identical low power RF signals for both the active and shield sections of the sensing probe. This design ensures that the switch remains unaffected by suspended dust or material in transit. When the media reaches the probe, the variation in the active signal actuates a potential free relay for precise alarm and control functions.

Top Mounted Magnetic Level Switch

Top Mounted Magnetic Level Switch

Level Switches

Flowtel Engineering provides high precision Top Mounted Magnetic Level Switches featuring hermetically sealed sensors for maximum durability. As the magnetic float passes the sensor points on the immersed probe, it triggers a switch change from NO to NC to automate your liquid level management. This versatile system allows you to adjust contact points based on your specific process needs, making it ideal for interlinking levels in parallel tanks. The design focuses on minimal wear and tear, ensuring that maintenance stays easy and cost effective even in high temperature environments reaching 200°C.

Side Mounted Magnetic Level Switch

Side Mounted Magnetic Level Switch

Level Switches

Flowtel Engineering manufactures high performance Side Mounted Magnetic Level Switches designed to handle diverse industrial operating conditions. These switches utilize a horizontal magnetic float that moves about a fulcrum as the liquid level changes. This movement activates the micro switch contacts (NO/NC), providing a reliable output for further industry processing. Our side mounted switches are ideal for space constrained installations where top mounting is not feasible. They are engineered for durability with minimal wear and tear, ensuring easy maintenance and a long operational life. For high turbulence applications, we also offer an external cage arrangement to ensure consistent and accurate switching.
