The Expert 2100 is designed as a dependable “workhorse” level transmitter for municipal and industrial water applications. It features a stainless steel diaphragm and polypropylene (PP) body, supports 2-wire 4–20 mA loop power.
Key Benefits:
- Accurate and stable year after year - High accuracy (±0.25% FS) with low drift and long-term stability (±0.5% FS per year).
- A proven workhorse for tanks and pump stations - The 2100 supports many common municipal applications, simplifying product selection and standardizing installations.
- Rag-resistant design - No sharp edges to help prevent debris buildup in wastewater environments.
Applications
Wastewater wet wells & lift stations
Rag-resistant housing design helps reduce debris buildup, supporting reliable level measurement in harsh, solids-laden environments.
Pump stations & sewer wells
Provides stable level feedback for pump control, alarms, and trending, where continuous operation and consistent signals are essential.
Water storage tanks (potable and process water)
Delivers dependable tank level measurement for inventory visibility, pump sequencing, and high/low level alarm setpoints.
Industrial process sumps & basins
Supports robust hydrostatic level monitoring in industrial water systems where a durable submersible transmitter is preferred.
