These instruments automatically perform proof tests
The Liquiphant FTL51B and FTL41 vibrating fork (vibronic) level instruments (photo) were introduced in January. 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 build-up. The economical, general-purpose FTL41 is similar to the FTL51B, but 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. — Endress+Hauser, Greenwood, Ind.
