The Liquiphant FTL51B and FTL41 vibrating-fork (vibronic) level instruments (photo) were recently launched. The FTL51B features Industry 4.0 and industrial internet of things (IIoT) capabilities, including access via wireless Bluetooth technology, automatic proof tests and verification, and easy commissioning via a mobile device. 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 buildup. The instrument works in process temperatures of –58 to 302°F and pressures up to 1,450 psi. It can be used in SIL2 and SIL3 hazardous locations, and has built-in automatic maintenance and verification functions. The general-purpose FTL41 works at lower pressures, up to 580 psi, and with a narrower temperature range of –40 to 302°F. 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 pushbutton test. The proof test diagnoses the sensor for corrosion and buildup, and ensures that the entire instrument is operating properly. — Endress+Hauser Group, Reinach, Switzerland
