Frequently Asked Questions

The 99.9% aluminum oxide ceramic diaphragm is chemically inert and resists buildup from biological growth and mineral deposits. Unlike metal diaphragms that can corrode, the ceramic maintains dimensional accuracy across years of exposure to corrosive media including wastewater, landfill leachate, and aggressive chemical solutions.

LoRa provides 1-5km typical range depending on terrain and obstacles, extending to 15km in open line-of-sight conditions. NB-IoT and 4G offer nationwide carrier coverage. WiFi covers standard router range (50-100m). LoRa and NB-IoT are optimal for remote installations without local network infrastructure.

The 7.4V/5000mAh battery provides 2-5 years of operation depending on wireless protocol and reporting frequency. LoRa with 10-minute intervals achieves 4-5 year battery life. WiFi and 4G consume more power and typically provide 1-2 years. External 12V/24V DC power is available for permanent installations.

316L stainless steel is more affordable and suitable for most applications with moderate corrosion requirements. The 99.9% AL₂O₃ ceramic option is recommended for highly corrosive media, biological applications, and situations where diaphragm buildup would affect measurement accuracy. Ceramic provides a flush, non-porous surface that resists fouling.

The HM210 is designed specifically for hydrostatic level measurement. It measures the pressure exerted by the liquid column above the sensor and converts this to a level reading. For simultaneous pressure and temperature measurement, consider the HM200H which combines multiple measurement parameters in a single device.

Standard cable lengths range from 3m to 200m depending on measurement depth requirements. PE cable is suitable for general applications (-25 to 80 degrees C), PUR cable offers enhanced chemical resistance (-25 to 70 degrees C), and FEP cable provides the highest chemical compatibility for aggressive media. Custom cable lengths are available on request.
