The Ideal Solution for Level Limit Detection in Storage Tanks

Apr 21 2008

Liquiphant M from Endress+Hauser (UK) is the ideal solution for both
high and low liquid level detection in storage tanks. In addition to being cost effective and easy to install, it’s also maintenance-free and
can be remotely tested without removal from the process. What’s more, its 40mm long forks and ¾ inch process connection makes Liquiphant M suitable for use in applications where space is at a premium.
Vibronic technology can be used as an excellent problem solver for overfill protection. Fully complying with the latest regulations issued
by the Health & Safety Executive, Endress+Hauser’s Liquiphant M is a
reliable solution for pollution prevention and safety operation in tanks storing hazardous substances. Liquiphant M also complies with IEC 61508 offering a SIL2/3 rating and the range includes ATEX certified
(EEx ia and EEx d) versions for hazardous area use.
Tried and tested technology: With over 2.5 million units already in the field, LiquiphantMismore than just a level switch. When uncovered, the Liquiphant’s forks vibrate at their resonant frequency. As it immersed in the liquid, the frequency reduces until it reaches the switch point, then an output is triggered. But how would you know if the system has ceased to function reliably due to corrosion?
Unique corrosion alarm: Unlike float switches, Endress+Hauser’s unique fork corrosion monitoring system means you can be you can be certain that when the resonant frequency rises above a critical point, LiquiphantM will raise the alarm. With vibration technology, build-up or sensor damage will also change the resonant frequency and raise the alarm, so you’ll know when there’s a problem before it is critical.
