Endress+Hauser introduces Promag L 400 with built-in Ethernet port and web server technology.Endress+Hauser has introduced the Proline Promag L 400 electromagnetic flowmeter for water and wastewater applications. It has an Ethernet port and built-in web server for easy data access and configuration via a web browser. The sensor has drinking water approvals and corrosion protection that allows it to be installed underwater, underground, and in saline environments. Sensors are available in nominal diameters from 2 to 90 in.

With the integrated web server, the transmitter can be accessed via a standard web browser. This allows engineers and maintenance technicians to configure all device functions without any special software, to upload and download configuration date for backup or copying to identical meters, and to access device, diagnostic, and process information.

The Promag L 400 has KTW/W270, ACS, NSF 61, and WRAS BS 6920 drinking water approvals, as well as custody transfer approvals to MI-001 and OIML R49 water meter standards. Accuracy is 0.2% of range, with factory testing on accredited and traceable calibration rigs.

An on-board HistoROM system provides data storage of all sensor, transmitter, and totalizer data, with no data loss if power is removed. The HistoROM system provides a built-in data logger, has an event logbook and parameter backup, and can be restored using .xml files through the web server. Data can also be accessed via the local graphic display. This capability also includes guided menus, setup wizards, 16 language options, help displays, and built-in simulation software.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
