DeltaSpan? LD37 External Anti-Corrosion Pressure Liquid Level Sensor Transmitter from Flowline

DeltaSpan? LD37 External Anti-Corrosion Pressure Liquid Level Sensor Transmitter from FlowlineThe LD37 general purpose anti-corrosion external mount pressure level transmitter provides continuous liquid level measurement up to 11.55’ (3.4m) of water column with a 4-20 mA signal output. Offered in two termination types, select the -S_01 model for cable termination or the -S_11 model for M12 connector termination. The LD37 pressure level sensor is well suited for clean liquids compatible with PTFE such as acidic and caustic chemicals.

External Mount

The externally mounted pressure sensor provides a simple, low-cost, level measurement solution for metal tanks, and is easily installed via a 1/4” tee or tap fitting located in the tank’s drain or inspection port.
