ATMI's liquids level measurement

Float level switches advantages

Liquid levels can be measured through different equipment, from float level switches to more sophisticated devices such as radars, capacitive level sensors, ultrasonic sensors, etc.

However, nowadays the float switch continues to be the simplest, most reliable, and  cheapest technology for liquid level measurement applications.

If your facilities are already equipped with a different level measurement system, we recommend you to use a float switch as a high level alarm (sound or light) in order to secure your installations and to prevent any overflows due to eventual failures of the electronic measurement devices.

ATMI offers a wide range of float level switches (simply designed for an easy installation) that ensure safe installations in a multitude of applications: drinking water meant for human consumption (ACS certified floats), aggressive liquids, hazardous environments (ATEX certified level regulators), as well as other liquids, such as clear, clean liquids, wastewater, mud, oil, diesel, etc.

It is highly recommended to visit ColeParmer’s website in order to verify the chemical compatibility of our devices specially with agressif liquid mixtures. ATMI can only provide approximate chemical resistance information and samples for testing purposes.
