Product News: Liquiphant FTL51B and FTL41 point-level instruments
Endress+Hauser releases Liquiphant FTL51B and FTL41 vibrating-fork (vibronic) level instruments. The FTL51B features Industry 4.0 and IIoT capabilities, including access via wireless Bluetooth technology, automatic proof tests and verification, and commissioning via a mobile device, according to its maker. In addition, operational clarity is provided by a high-visibility LED.

The Liquiphant FTL51B can be used in storage tanks, containers and pipes for point-level detection of all types of liquids. The instrument’s vibronic sensor is not affected by changing media properties, flow, turbulence, gas bubbles, foam, vibration or build-up, according to Endress+Hauser. The instrument works in process temperatures of -58 to 302°F (-50 to 150°C) and pressures up to 1450 psi (100 bar). It can be used in SIL2 and SIL3 hazardous locations, and has built-in automatic maintenance and verification functions. The economical, general-purpose FTL41 is similar to the FTL51B, but works at lower pressures, up to 580 psi (40 bar), and with a narrower temperature range of -40 to 302 °F (-40 to 150 °C).
Both perform proof tests, with the FTL51B meeting SIL and WHG (Water Resources Act) requirements. The proof test can be activated remotely at a control system, or locally via a magnet or push button test. The proof test diagnoses the sensor for corrosion and build-up, and ensures the entire instrument is operating properly. Verification can be activated either manually or automatically via Endress+Hauser’s Heartbeat Technology, providing a verification report sufficient as documentation for various regulatory agencies.
Access via Bluetooth technology and a mobile device—such as smartphone—allows a user to identify each device, commission it, check the status, start a proof test, and download verification documentation, according to Endress+Hauser. Bluetooth has a range of 33 ft, allowing a technician to access Liquiphant instruments installed in hard-to-reach locations, such as at the top of tanks.
