Level Instruments

What are Level Instruments?

Level Instruments are essential devices used to detect, monitor, and control the level of liquids, slurries, or solids in tanks and process vessels.
They ensure stable process control, prevent overflow or dry running, and maintain accurate measurement in industrial automation systems.

Types of Level Instruments

1. Level Switch

A Level Switch is a control device that detects the presence or absence of liquid at a specific point.
Once the liquid level reaches the preset position, it sends an on/off signal to start or stop pumps, alarms, or valves.

2. Level Meter

A Level Meter (or Level Transmitter) provides continuous level measurement of liquids or solids in tanks or pipelines.
It converts the measured level into a standard output signal (4–20 mA or RS485) for process control.
