🔍 Key Concepts

• Location and function of sensor probes in an oily water separator • Difference between an oil level sensor inside the separator and an external oily‑water content monitor (OCD) in the discharge line • Why the probe is mounted at the top of the separation chamber where the oil layer collects

💭 Think About

• Look at where label A is installed relative to the oil layer and water outlet. What condition would a probe in that exact spot need to detect? • Compare the symbol and position of A with the separate box marked "OCD Monitor" on the right side. Which option describes something mounted in the tank vs. an external instrument in the discharge line? • Ask yourself: is this device checking the quality of the water being discharged, or the level/interface of fluids inside the separator tank?

✅ Before You Answer

• Confirm whether the OCD/oily‑water monitor in this diagram is drawn as a separate control box connected by piping and wiring, not as a probe in the tank roof. • Note that a relief valve would normally be drawn on a pressured line or top of a tank with a valve symbol and discharge line, not as an electrical probe or sensor. • Check if the probe at A is located where separated oil accumulates at the top of the vessel, which would influence whether it senses oil level, water level, or mixture quality.
