Industrial Level Control with Flowline LD34-S111
The Flowline LD34-S111 is a DeltaSpan LD34 Small Bore Pressure Level Transmitter designed for industrial liquid-level measurement, monitoring or control applications. Use the exact model number when comparing replacement or new-installation requirements, because connection, output, range and enclosure options can vary across Flowline configurations.
Where This Model Fits
This Flowline configuration is intended for level-related process applications where reliable model matching and documented installation parameters are important. It may be used as part of monitoring, alarm, pump-control or measurement systems depending on the model configuration.
Documented Features
- Welded 316 SS body and 316 SS nose cap provide years of trouble free service
- Tapered body top prevents damage or snaring when removing from installation
- Incorporates lighting and surge protection
- Provides precise output readings with its 0.25% of full scale accuracy
- Ideal for applications with heavy foam and vapors
- Connects directly to PLC/SCADA or display
Before purchase, compare the complete model code with the application requirements. Check tank dimensions, process connection, wetted materials, power or signal needs, measurement range and environmental conditions where those values apply. This helps prevent selecting a similar-looking Flowline model with a different configuration.
Ordering Checklist
- Confirm part number LD34-S111
- Compare range and connection requirements
- Verify electrical/output requirements when applicable
- Check wetted-material compatibility with the process
For maintenance teams, integrators and OEM users searching for Flowline LD34-S111, the model-specific identification makes it easier to match the product to a documented Flowline level-control system without relying on appearance alone.
