Product roundup: Level continuously improves media measures

May 28, 2020
From liquids to bulk solids, level sensing and measurement refinements keep on coming

Point levels and proof tests

Liquiphant FTL51B and FTL41 vibrating fork (vibronic) level instruments detect liquid point levels, and provide proof test, verification, and IIoT functions. FTL51B has a vibronic sensor that's unaffected by changing media properties, flow, turbulence, bubbles, foam, vibration or build-up. It works at -58 °F to 302 °F (-50 to 150°C) and pressures up to 1450 psi (100 bar). The economical FTL41 works at lower pressures, up to 580 psi (40 bar), and with a narrower temperature range of -40 °F to 302 °F (-40 to 150 °C).
