Product Description
Product Overview Product overview
This series of float level gauges offers continuous liquid level measurement unaffected by physical and chemical properties such as foam, conductivity, dielectric constant, pressure, vacuum, steam, condensation, air bubbles, boiling effects, and density variations. The HART® interface enables simultaneous measurement of both interface and overall liquid levels. The displayed level reading can be directly proportional to either height or volume. Process connections, guide tubes, and floats are available in a variety of materials, including stainless steel, titanium, and various types of plastic.
Product Principle THE PRODUCT PRINCIPLE
The system employs reed resistor chain technology and measures liquid levels based on the principle of magnetic conduction. The magnetic field lines from the magnet embedded within the float pass through the guide tube, inducing the reed switches and resistor chain inside. This interaction generates a voltage output—via a three-wire voltage divider—that is directly proportional to the liquid level. Thanks to the tightly packed arrangement of the reed switches and resistor chain, the voltage changes nearly continuously.
