The MicroPulse System makes use of a single solid-state sensor per tank. The MicroPulse sensor measures
the static (head) pressure at the bottom of the tank and transmits this information to the MicroPulse System
Monitor. Knowing this pressure value, after a one-time calibration has been performed, the MicroPulse
System will calculate and accurately display the tank level in 1/8 increment.
A single sensor is installed on the sidewall of each tank, near the bottom, via a 3/4" female NPT spin-in
thread. The sensor is solid state, there are no moving parts to wear or maintain. Because the principle of
operation does not involve any electrical current flow through the tanks contents (conducted or induced),
the nature of the fluid in the tank is unimportant.
The monitor system has been calibrated at the factory and should never need another calibration. If you feel
the system is not operating correctly, please contact CATCON Products or a local Airstream dealer. The
following instructions are provided for qualified service technicians.
