244LD

🧪 What This Data Means — For Quick Client Selection

âś” Best choice for interface measurement

244LD accurately detects two-liquid interface (oil/water, chemical layers) where radar/ultrasonic are unreliable.

âś” Ideal for extreme conditions

Works reliably in very high temperature, high pressure, and corrosive environments—perfect for boilers, reactors, and refinery vessels.

âś” Not affected by foam, vapour, turbulence

Buoyancy measurement is stable even when radar/ultrasonic fail due to heavy vapours, foam, or agitation.

âś” Suitable for density measurement

Torque tube detects density variations—helpful for chemical concentration & SG monitoring.

âś” Requires vessel-mounted chamber

Installation is side/top on a cage or bypass chamber—needs mechanical envelope space.

âś” Maintenance-friendly

Robust mechanical design with minimal recalibration needs; long service life in continuous operations.

 

Description

Schneider 244LD is a high-performance displacer-type level transmitter for measuring liquid level, interface, and density in pressurized or atmospheric vessels. Using torque-tube technology, it delivers reliable output even in high-temperature, high-pressure, or corrosive conditions. Ideal for boilers, chemical tanks, hydrocarbons, separators, condensate vessels, and refinery applications.
