The OPTEK brand can identify if liquid is present in clear tubes that come in a variety of sizes. Its opaque plastic housing enhances ambient light rejection. It is also available as a self-calibration module. When output reference circuitry is added, multiple output states such as “fluid present,” “no fluid present,” and “no tube present” can be recognized. Common applications include non-contact fluid sensing of IV fluid, oils and other petroleum products, and colored fluids.
