Hydrostatic Level measurement Waterpilot FMX21
- SKU:
- Hydrostatic Level measurement Waterpilot FMX21 series
- Weight:
- 0.00 Grams
Description
Application
The Waterpilot FMX21 transmitter, featuring a capacitive, oil-free ceramic measuring cell, is widely utilized in hydrostatic level measurement for both process and environmental applications. It includes HART output for adjustable measuring ranges and the option for density-compensated level measurement. The transmitter is certified for use with drinking water and includes integrated temperature measurement. Additionally, versions are available for wastewater, sludge, and saltwater applications.
Available in three versions: for drinking water, wastewater and sewage, and saltwater.
Process connections include suspension clamp and cable gland.
Operating temperature range: –10 to +70°C (14 to 158°F).
Measuring range: 0 to 20 bar / 200 m H2O (0 to 300 psi / 600 ft H2O).
Accuracy: ±0.2%, with a "Platinum" version offering ±0.1%.
Certified for international explosion protection, marine approvals, and drinking water.
Benefits
- Durable, high-purity ceramic sensor (99.9% Al2O3) with strong resistance to overload.
- Flexible 4 to 20 mA scaling with integrated HART 6.0 output.
- Superior accuracy with temperature-compensated density correction.
- Simultaneous measurement of level and temperature, with an optional integrated Pt100 temperature sensor.
- A comprehensive range of accessories for complete measurement point solutions.
- Climate-resistant sensor with fully potted electronics and a dual-filter pressure compensation system.
- Compact 22 mm (0.87") outer diameter version, ideal for drinking water applications and for boreholes and wells with narrow diameters.
