Q

Remote water level indicators, operate on the principle of __________.

🔍 Key Concepts

• Remote water level indicators on boilers and tanks • How water level can be measured indirectly using physical properties • The role of a reference (constant) column when measuring level remotely

💭 Think About

• Ask yourself: which option describes a method that can send water level information to a remote location using a measurable physical change, like pressure or height? • Consider: do remote indicators normally depend on optical (light), chemical, or mechanical/pressure-based effects in engineering systems? • Think about how a constant head tank or column might be used to compare against the changing level in a boiler drum.

✅ Before You Answer

• Verify which choice actually involves a comparison between a changing level and a fixed reference. • Check whether refractive or chemical properties are normally used for robust, continuous level indication in steam plants. • Confirm that the method you pick could be easily converted into a pneumatic or electrical signal that can be read at a distance.
