Electronic Drum Level Indicator adopts multi-probe column design, rated up to 207 bar at saturated temperature. It supports 8–48 channels, dual power redundancy and self-diagnosis with no spurious trips. Equipped with isolated 4-20mA output and remote display, it is optional explosion-proof and suitable for super-critical working conditions.
➤ Electronic Drum Level Indicator Levelstate EDLI is an advanced electronic water level monitoring system. An EDLI system includes multiple Probes fitted to a Water Column and connected to an Electronic unit, which is widely accepted as a reliable & maintenance free equipment. Pressure parts available for applications upto 207 bar at 370°C as standard. Electronics available in various configurations and include Type 201, Type 202 and Type 202B.
At its core, EDLI uses a multi-probe water column system that distinguishes steam from water based on resistivity thresholds. Each probe operates independently, feeding data to a robust electronic unit that displays water levels via high-intensity LEDs and triggers alarms or trips at pre-set thresholds. With configurations ranging from 8 to 48 channels, EDLI adapts to diverse plant requirements—from feedwater heaters to turbine bypass sumps.
