Level controller series

LF-1 liquid level transmitter

 

 

The LF-1 submersible pressure transmitter is suitable for level measurement of oils and fuels, e.g.

■ Level measurement of oil and fuel storage containers and systems

■ Monitor overfilling and empty running

■ Battery-powered liquid level measurement system

The LF-1 submersible pressure transmitter is designed for oil and fuel related applications, it meets IECEx, ATEX certified explosion protection requirements, optional intrinsically safe electronic system for hazardous areas, and the LF-1 is also suitable for outdoor measurement.

Use:

Intrinsically safe level transmitters convert hydrostatic pressure into electrical signals to control liquid levels in explosion-hazardous environments.
