About MEASUREMENT OF LEVEL BY CAPACITANCE METHOD APPARATUS

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.

Versatile Level Measurement

This apparatus offers versatility by supporting a wide range of conductive, non-corrosive liquids and is compatible with tanks made from plastic, glass, or stainless steel. The units robust rod-type electrode and customizable probe ensure accurate measurement across various scenarios in laboratory and industrial environments.


Advanced Safety and Compliance

Safety is prioritized through overvoltage and short-circuit protection, while the IP54 enclosure ensures durability under harsh conditions. Audio/visual alerts keep operators informed, making it suitable for rigorous engineering testing situations where operator awareness and equipment longevity are vital.


Precision Readings and Easy Calibration

Precise liquid level readings are made possible with 1% FS accuracy and a 1 mm resolution. Multi-point manual calibration allows fine-tuning for different setups, ensuring reliable operation. The clear digital LCD display and rapid response time enhance usability for both manual and automatic control modes.
