Builders wanting to provide their own indicators can purchase the UFS-AN and UFS-T sensors separately from the kits shown elsewhere in this website. These are infrared based sensors that can measure fuel, water, hydraulic fluid, brake fluid, and most other liquids that don't contain particulate materials. (Particulates can attach and accumulate on prism and cause false indications of air.) The UFS-AN is designed for in-tank applications; the UFS-T is designed for in-line applications.

FYI - For those who are replacing one of the older Pillar Point Avionics UFS-Ts:
We have increased the size of the ports on the UFS-T. They are 1/4" NPT instead of 1/8" NPT. We have also increased the overall size of the fitting to allow for two holes that can be used for mounting. In the next production run we will make some Ts that can be used as a direct replacement for the previous design but they will be special order.

Connectors, pins, and complete wiring instructions are included with each order.

Key Benefits:

• Immediate warning of the presence of air.
• Reliable indication of the presence of fuel or other liquids.
• Low-cost and high value devices.
