(1) Direct methods:- This is the simplest method of measuring liquid level. In this method, the level of liquid is measured directly by means of the following level indicators: (i) Hook-type Level Indicator. (ii) Sight Glass. (iii) Float-type. (iv) Float and shaft liquid level gauge. (i) Hook-type Level Indicator: When the level of liquid in
Liquid level measurement - Basics 101. Part 1. White Paper. John Schnake. Executive Summary. The perfect level technology that works for every liquid level and point level application does not exist. Hydrostatic pressure has been around, it seems forever, and is proven in many applications. Non-contact radar and guided

either a liquid, the top of a solid, or the interface of two liquids. Precise control of the level of liquid in a tank, reactor, or other vessel is important in many process applications. Level measurement is often used for inventory management. To provide good control, accurate measurement is essential and several devices.
Compute tank inventories of hydrocarbon liquid products and utility liquids. 2. Protect equipment such as columns, compressors. turbines and pumps from damage. 3. Protect operating and maintenance personnel against injury resulting from hydrocarbon, corrosive or toxic liquid spillage. 4. Protect the environment from the
What is the material to measure: liquid or solid? ? Can the sensor be placed in the chamber or it should be external? ? Will you need contact or non-contact level measurement? What's the acceptable degree of accuracy? ? What are the application's temperature and pressure ranges? Is the specific gravity of the liquid
Vapor velocity and liquid velocity may be different. – Flow regime is not known. • Measurement of void fraction (A v. /A) is more straightforward. – Capacitive meter based on different dielectric constant. – Optical techniques. • Total mass flow rate can be determined in some part of the circuit where the fluid is single phase
Liquid Level Measurement. A pressure transmitter can be used to determine the liquid level in a tank, well, river or other body of liquid. The pressure at the bottom of a liquid filled container is directly related to the height of the liquid. The transmitter measures this hydrostatic head pressure and gives the resulting liquid level.
