Liquid ammonia storage tanks require 2 sets of level gauges – how should one make a choice?
Thread Content
Due to the significant changes in temperature and pressure of liquid ammonia, which in turn causes changes in its density, differential pressure level transmitters do not provide accurate readings.
Only measure the liquid level, not the density!
Magnetic flap level gauge with remote transmission, offering high measurement accuracy and being unaffected by pressure or temperature fluctuations.
Storage equipment for hazardous chemicals requires two separate level gauges for sampling: one with magnetic flip switches for on-site display, and the other with a radar level gauge mounted at the top, which can mitigate the impact of aerosols through waveform suppression; brands such as Coriolis, E+H, and Vaga are recommended due to their good cost-performance ratio
Even with an E+H guided-wave radar, it is still affected by mist
