Product Details Supplier Info More products

Endress and Hauser’s Instrumentation for Aeration Control package is aimed at advanced aeration control strategies and can include instruments that measure dissolved oxygen, nitrate, ammonium, pH, suspended solids, temperature, air flow rates, air pressures and water levels in aeration basins.

The series of aeration control sensors can connect to a plant’s PLC or SCADA system using 4–20mA with HART, Profibus or other digital interfaces.

The combination of sensors and transmitters allows users to ensure that the correct amount of air is blown through a system at the right basin level, and that nutrients are removed from water efficiently.

Key product features

  • Liquiline CM442 transmitters and CAS40D sensors monitor the ammonium and nitrates of the incoming and/or treated water with a single sensor array.
  • They can also provide additional parameters such as pH, temperature, chloride and potassium.
  • The CM442’s dual-channel digital technology enables one transmitter to measure ammonium, nitrates, dissolved oxygen, temperature and pH.
  • Oxymax optical or amperometric dissolved oxygen sensors with the digital Memosens protocol monitor levels of dissolved oxygen.
  • A T-Mass 65I thermal mass insertion flowmeter can be placed in the blower air line in order to ensure the air-delivery system is working properly.
  • An Endress and Hauser Cerabar S pressure transmitter can be used to to measure air line pressure.
  • A Prosonic FMU90 ultrasonic or a Waterpilot FMX21 hydrostatic instrument are available for measuring and controlling levels.
