Float Switches | Transmitters
With decades of experience in level measurement and process control, iCenta Controls supplies reliable float level switches and transmitters for accurate monitoring of liquid levels in tanks, vessels, and process systems. Designed for dependable operation in industrial and commercial environments, these devices help automate control, prevent overfilling, and maintain safe system operation.
 What Are Float Level Switches and Transmitters?
Float level switches and transmitters are devices used to detect, monitor, or continuously measure liquid levels within a tank or vessel. Float switches typically provide point-level detection, activating a signal when liquid reaches a set level, while float transmitters deliver continuous level measurement for monitoring and control purposes.
These instruments are widely used because of their simplicity, reliability, and suitability for a broad range of liquids and operating conditions.
How Do They Work?Â
Float level devices operate using a buoyant float that rises and falls with the liquid level. In a float switch, the movement of the float activates an internal switch at a predetermined point, triggering an alarm, pump, or control action.
Float level transmitters work in a similar way but provide continuous level data, often converting float movement into an analogue output signal for display or integration with control systems. This straightforward operating principle makes them a dependable and cost-effective solution for liquid level monitoring.
