How to use a radio frequency admittance level switch
Thread Content
The setup involves enamel tanks at a temperature of 130 degrees; the material handled is an organic substance containing a small amount of 68% sulfuric acid. Fluorinated fork-type sensors are currently being used, but the instruments malfunction from time to time. Tantalum tuning forks are too expensive. Someone at Haichuan recommended radio admittance level switches – how effective are they? What are some well-established foreign brands of radio admittance level switches?
A well-known foreign brand is AMETEK-DE
RF admittance is essentially an upgraded version of a capacitive level gauge; it can be used whenever the storage tank is a conductor. For 68% sulfuric acid, a fluoropolymer-lined material is required, special treatment is needed, but it can be used. The top brands are definitely Ametek, or E+H; British Ideal is also a good option.
