MEASUREMENT OF LEVEL BY CAPACITANCE METHOD APPARATUS

Product Description

Specification:

MEASUREMENT OF LEVEL BY CAPACITANCE METHOD APPARATUS

The present set-up is designed to study the working principle and calibration procedure of capacitance type level transmitter.

The set-up consists of a probe which is mounted in a level tank with graduated scale.

Water is poured in the level tank manually and response of the level transmitter is indicated on the Level Indicator.

Output of the transmitter can be measured using Digital Current meter.

A drain valve is provided at the bottom of the level tank which enables the student to observe and measure the response of capacitance type level transmitter at different liquid heights.

The set-up is complete with Level tank, level transmitter, current indicator and necessary piping.

All component and accessories are properly mounted on the rigid MS structure and fitted on a base plate to form at able top set-up.

Experimentation/learning objectives:

To study of working principle and calibration procedure of capacitance type level transmitter.

To study of linearity, accuracy and repeatability of capacitance type level transmitter.
