Endress+Hauser's Instrumentation for Aeration Control package connects to a plant's PLC or SCADA system via 4-20mA
Endress+Hauser's Instrumentation for Aeration Control package is geared toward advanced aeration control strategies. Instruments available measure dissolved oxygen, nitrate, ammonium, pH, suspended solids, temperature, air flow rates, air pressures and water levels in aeration basins.
The Endress+Hauser family of aeration control sensors connects to a plant’s PLC or SCADA system via 4-20mA with HART, Profibus or other digital interfaces.
Endress+Hauser's Liquiline CM442 transmitters and CAS40D sensors, both with the digital Memosens protocol, monitor the ammonium and nitrates of the incoming and/or treated water with a single sensor array that can provide additional parameters such as pH, temperature, chloride and potassium.
Endress+Hauser Oxymax optical or amperometric dissolved oxygen sensors with the digital Memosens protocol monitor dissolved oxygen to make sure minimum levels are maintained. With the CM442’s dual-channel digital technology, one transmitter can measure ammonium, nitrates, dissolved oxygen, temperature and pH.
Because blowers must overcome the hydrostatic pressure of the basin to force air into the process, an Endress+Hauser Cerabar S pressure transmitter is available to measure air line pressure. A Prosonic FMU90 ultrasonic or a Waterpilot FMX21 hydrostatic instrument can be used to measure and control level.
