The Fathom tank level sensor measures the fluid level in all plastic holding tanks by transmitting a radar wave through the tank wall and receiving the returned signal.
Exterior Installation
The device is very simple to install by “welding” it to the top of the tank using industrial strength adhesive that is specified to withstand extreme temperatures, vibration, and the test of time.
Solid Enclosure
The Fathom radar electronics are encased in durable over-molded plastic that prevents penetration of liquids and dust.
RV-C Compatible
Each Fathom sensor communicates over RV-C natively. Thus, eliminating the need for additional hardware to communicate with RV-C based control panels.
Clear Precision
Utilizing cutting edge radar technology, the Fathom radar can measure small changes in fluid levels with a 0.25 cm accuracy.
Powerful Technology
The Fathom sensor’s radar-based design utilizes the same technology that is used for level monitoring in many industrial storage tanks because of its reliability and accuracy.
