Level Measurement Errors

 INTRODUCTION There are many methods to measure level of a system or a tank (Direct and indirect). Let us discuss about the differential pressure level measurement technique. The indication of fluid level is based on the pressure exerted on a differential pressure (DP) cell by the height of the liquid in the vessel. Level Measurement …

Nuclear Level Measurement

Introduction Continuous nuclear level measurement is typically used where most other technologies are unsuccessful. Different radioactive isotopes are used, based on the penetrating power needed to pass through the tank. Radiation from the source is detected on the other side of the tank. Its strength indicates the level of the fluid. Theory Nuclear continuous level measurement works …

Ultrasonic  level Measurement

INTRODUCTION Ultrasonic makes use of sound waves in the 20 – 200 kHz range (above the range for human hearing). A transducer mounted in the top of a tank transmits sound waves in bursts onto the surface of the material to be measured. Echoes are reflected back from the surface of the material to the …

LASER LEVEL MEASURMENT

Introduction There are different kinds of indirect level measuring methods.In this session we are gonna discuss about laser level measurements.The working principle of laser level measurement is detecting the time taken by laser source for transmission and reflection back from the material surface. The laser level transmitter either uses triangulation, time of flight or confocal …

Bubbler Level Measurement System

Introduction If the process liquid contains suspended solids or is chemically corrosive or radioactive, it is desirable to prevent it from coming into direct contact with the level transmitter. In these cases, a bubbler level measurement system, which utilizes a purge gas, can be used.   THEORY As shown in Figure, a bubbler tube is …
