JUMO MAERA S25

Hydrostatic level gauges, Pressure sensors

Fields of application

JUMO MAERA S25 is a compact hydrostatic level transmitter for continuous liquid level measurement in tanks and reservoirs. The piezoresistive measuring element with stainless steel diaphragm ensures stable measurement, and the integrated atmospheric pressure compensation allows for precise determination of the liquid column height. Suitable for rainwater, grey water, heating oil, diesel and similar systems.

Features:

  • Measuring height 2.5–10 mH₂O
  • Hydrostatic, continuous level measurement
  • Piezoresistive silicon sensor
  • Accuracy up to ±0.3 %
  • Stainless steel construction
  • Protection class IP68
  • Submersible up to 20 m
  • Reverse polarity protection
