🔍 Key Concepts

• Trace the water transducer (WT) symbol in the illustration and note which pipeline it is installed on. • Think about how a transducer works in general: it converts one form of energy (pressure, sound, etc.) into an electrical signal. • Look at the MARST1 Alarm Indications Program Unit and see what the alarms related to the transducer are telling you about its function.

💭 Think About

• Is the transducer monitoring water going into the separator, or the effluent water coming out of the separator? Follow the color/line coding. • Does the function described by the alarms sound more like measuring how much water flows, or measuring the quality/contents of the water (oil in water)? • Which choice best matches a device that can send a signal to an electronic alarm unit based on what it detects in the water line?

✅ Before You Answer

• Verify on the diagram which line is labeled with WT and confirm whether it is in an oil line or a water line. • Check the MARST1 unit for any reference to transducer signal minimum value or transducer fault and ask what kind of device would generate such a signal. • Eliminate any choice that contradicts the physical location of the transducer as shown on the piping diagram.
