Liquid Level Switches

Endress+Hauser released Liquiphant FTL31 and FTL33 liquid level switches based on vibrating tuning fork technology.

Endress+Hauser released Liquiphant FTL31 and FTL33 liquid level switches based on vibrating tuning fork technology. The sensors are excellent replacements for float switches or conductive, capacitance and optical sensors. The FTL31 is designed for the chemical, oil and gas and other industries, while the FTL33 is more suited for use in the food and beverage industry. Both sensors also work in areas where those measuring principles are not suitable due to conductivity, build-up, foam, turbulence, flow conditions or air bubbles. The level switches can be installed in any vertical or horizontal position in a vessel, pipe or tank. Foam formation, changing conductivity or density does not affect their function. Both level switches have an external function test feature and an LED indicator for on-site testing. The Liquiphant FTL33 meets food industry requirements with 3-A and EHEDG certificates. It's designed to work in applications where CIP and SIP cleaning takes place, and has a stainless steel enclosure with optional IP69K protection. It can be used in storage tanks, mixing vessels and pipes where internal and external hygiene requirements are particularly stringent. CRN, EN10204-3.1 material certificate, and marine certifications are available.
