Endress+Hauser’s new Liquiphant range uses the vibronic principle to ensure safe and reliable point level detection. Both the Liquiphant FTL31, for utilities and industrial applications, and the FTL33, for use in the food and beverage industry, are easy to select and install and are available on short lead times through Endress+Hauser’s new E-direct website.

Liquiphant is designed for minimum or maximum level detection in pipes and vessels. It offers safety and durability even in difficult applications with changing media properties, build-up, external vibrations or fluctuating temperatures, for example during CIP or SIP cleaning. According to the company, the Liquiphant is a true ‘plug and play’ device, with no need for calibration or adjustment.

The FTL31 is a point level switch for liquids in tanks, vessels and pipes. It is designed for overfill prevention or pump protection in applications such as cleaning and filter systems and in cooling and lubrication vessels. Along with the FTL33, it is suitable for applications in which float switches or conductive, capacitance and optical sensors cannot be used due to conductivity, build-up, turbulence, flow conditions or air bubbles.
