Endress+Hauser FTW31: Conductive Liquid Level Sensing
The Endress+Hauser FTW31: Conductive Liquid Level Sensing probe provides a straightforward yet highly reliable method for point level detection in conductive liquids. Its advanced design offers remarkable flexibility, supporting multipoint detection with up to five distinct switch points on a single rod. This innovative feature significantly streamlines installations and reduces the overall cost of monitoring systems, making it an exceptionally practical solution for a wide spectrum of industrial applications where precise liquid level management is paramount.
Detecting Liquids With 10μS/cm Conductivity
This versatile instrument is specifically engineered for detecting liquids with 10μS/cm conductivity. It is perfectly suited for critical safety functions such as overfill prevention, ensuring that tanks do not exceed safe fill levels and preventing potentially hazardous spills. Additionally, the FTW31 provides robust dry running protection for pumps, safeguarding them from damage caused by operating without sufficient liquid. It’s also an excellent choice for sophisticated two-point pump control or detailed multi-point level monitoring within various process vessels.
Multipoint Capability Simplifies Installation
Leveraging multipoint capability simplifies installation procedures and reduces system complexity. The FTW31’s unique design allows a single probe rod to serve as up to five individual level sensors. This consolidation dramatically cuts down on the number of probes, associated wiring, and installation points needed within a tank or vessel. This efficiency is particularly beneficial in complex process setups requiring granular level monitoring for optimized operations, enhanced safety protocols, and accurate inventory tracking, all managed effectively by a single, robust device.
Reliable Operation, No Calibration Needed
Enjoy reliable operation, no calibration needed with the FTW31. This device is pre-configured with standard settings optimized for the most common conductive liquids, eliminating the need for time-consuming and intricate on-site calibration. The absence of moving parts within the process environment guarantees an extended service life, ensuring consistent, wear-free operation and minimizing the potential for blockages. This translates directly into reduced maintenance requirements and reliable, uninterrupted performance throughout its operational lifespan.

This high degree of adaptability ensures accurate installation and peak performance, whether monitoring shallow containers or deep industrial reservoirs. The added convenience of simple rod shortening further enhances its suitability for a broad array of industrial configurations and specific user needs.
Robust Threaded Process Connections
Featuring robust threaded process connections, the FTW31 guarantees secure and dependable integration into your existing plant infrastructure. It comes equipped with standard thread sizes, including G 1 1/2 and NPT 1 1/2″, which are widely recognized and utilized across numerous industries. This inherent compatibility simplifies the installation process, often negating the need for specialized adapters or custom fittings. The durable construction of these connections ensures a reliable seal and consistent performance, even when subjected to varying process pressures and temperatures, reinforcing the device’s overall operational integrity.
Certified for Explosion Protection
The Endress+Hauser FTW31 is certified for explosion protection, making it suitable for deployment in hazardous environments. It carries international explosion protection certificates, which are critical for ensuring safety and compliance in areas where flammable gases or dust may be present. Furthermore, its safety approvals include leakage detection capabilities, often linked with WHG (Water Resources Act) compliance for overfill prevention, adding an extra layer of security and regulatory adherence. These certifications highlight the FTW31’s readiness for demanding and safety-critical industrial applications.
