Remote Actuator Controls Provide Safer, More Efficient Wastewater Treatment Application

Above ground wastewater valve controls
Above ground wastewater actuator controls.
A wastewater treatment plant installed six new AUMA SAR electric actuators for modulating duty to control the dosing of chemical additives. These actuators are used for modulating duty to handle the high-precision dosing of short-chain fatty acids, used to support the growth of microorganisms and help to remove phosphorus from the wastewater. 

The actuators are situated below ground, with their AC actuator control systems mounted above the ground. This is done for both for both safety and convenience. This arrangement is made easy thanks to the modular design of AUMA actuators. AUMA actuator controls can be mounted up to 325 feet from the actual actuator (motor and gearbox).

When workers have to access equipment underground, it requires special safety needs and procedures. These include the use of qualified personnel and gas detection tests to ensure sufficient oxygen as well as to rule out flammable of explosive potentials. Locating the actuator controls above ground level, in combination with non-intrusive actuator versions, reduces underground work to a minimum, thus helping to save time and cost.

Below ground wastewater valve controls
Below ground motors and gearboxes.
The split-level installation also provides diagnostic and local control from a more comfortable position. The graphical interface and all operational, data logging and diagnostic features provided by the intelligent AC actuator controls are easily accessible. These actuators also use Profibus DP-V1 to communicate with the plant’s main distributed control system. Local AUMA Service took care of installation and commissioning on site.

Seametrics iMAG Series Electromagnetic Flowmeter

The Seametrics iMAG-Series is the most economical flanged electromagnetic flowmeter on the market. With electrodes designed to discourage fouling, it is available in 3” to 12” pipe in municipal or industrial water, waste and reclaimed water, pump stations, and packaged plant applications. Minimal straight pipe requirements allow iMAG-Series meters to be used in piping configurations where there is little space between the meter and an elbow.

iMAG-Series meters are CE certified, certified to NSF/ANSI standard 61 and are rated IP68 for applications where the meter may be operated under water to a depth of at least 10 feet (3 meters) continuously.

The display can be meter mounted or remote, and both rate and total indication are standard. Rate and total units and pulse scaling can be set via the front panel touch key pad by the user.

Bidirectional flow reading is standard with totals available in forward, reverse, net flow, batch forward flow, and batch reverse flow. Batch totals can be reset.

A power/output cable allows outputs for use with a variety of Seametrics and other displays and controls for remote reading and telemetry applications. Pulse output is standard on all models and 4-20mA passive current loop is standard on the iMAG 4700p. In addition, 4-20mA loop, HART protocol, high speed digital, and Modbus® protocol outputs are optional on the externally powered units, depending on model.

The SOR 815 LT Submersible Level Transmitter


The SOR 815LT transmitter is a rugged, compact, loop-powered instrument that accurately and reliably measure levels for many types of liquids. The SOR 815LT indicates level by continuously monitoring the static pressures of the liquids, using high-performance pressure sensors. The 815LT has a corrosion-resistant 316 stainless steel, seal welded housing, and a high-density Polyethylene (HDPE) cable jacket for compatibility with most liquids. A PVC self-flushing nose cone can also be provided to prevent clogging, or standard configuration offers dual 1/4” NPT female / 1/2” NPT male connections for rigid mounting. The transmitters are vented at the surface through a tube in the cable to reference atmospheric pressure.

AUMA Electric Actuators Now Support Industrial Ethernet

 Industrial EthernetEthernet enables computers to communicate over one network - in today's environment, communication between machines would not be feasible without it. First created in the 1970s and subsequently standardized as IEEE 802.3, Ethernet is the leading standard in office settings for data networks today.

"Industrial Ethernet" defines the improvements that allow Ethernet to be used in industrial automation, even for critical applications. Industrial Ethernet is Ethernet applied to an industrial environment, often requiring more robust connectors, wires, and, most importantly, better determinism. 

Industrial Ethernet (IE) is the use of Ethernet with protocols that provide determinism and real-time control in an industrial setting. Factors such as high reliability, robust communication, and device exchange during running operation are crucial. Industrial Ethernet utilizes specific protocols in combination with Ethernet to accomplish improved determinism. These protocols are already widely available and for which integration into the DCS is straightforward. PROFINET®, EtherNet/IP®, EtherCAT®, and Modbus TCP/IP,  are some of the most common.

Industrial Ethernet Topology
Industrial Ethernet Topology with Electric Actuators

EtherNet/IP® is an industrial network protocol that adapts to the Ethernet standard to the Common Industrial Protocol. EtherNet/IP® is one of the USA's leading industrial protocols and is commonly used in a variety of sectors including factory, hybrid and process control.

Industrial Ethernet
Electric Actuators using Industrial Ethernet in a water
treatment plant (AUMA)
AUMA, a leading manufacturer of electric actuators, is continuing to invest in pioneering Industrial Ethernet communication and now offers an Ethernet/IP® interface.

Ethernet/IP® is the third Industrial Ethernet standard that AUMA supports, in addition to PROFINET® and Modbus TCP/IP.

Ethernet/IP® offers superior connectivity and enhanced network flexibility. With bandwidths up to 100 Mbit/s, AUMA actuators with Ethernet/IP provide reliable and rapid exchange of both cyclic process data and acyclic diagnostic data from the actuators.

Industrial Ethernet has many technical advantages:
  • Transmission of real-time and IT data via a common medium
  • Virtually unlimited number of participants and network expansion
  • Flexible topologies which can easily be scaled and expanded
  • Quick transmission even of extremely large data volumes
  • Integration of web servers and IoT interfaces such as OPC UA within the device
  • Simple access to field level device data without proprietary gateways
  • Reliable in operation, no complex termination, simple maintenance
  • Future proof
