New MR Flow Transmitter from Hedland combines state-of-the-art digital signal processing technology with the rugged proven technology of a piston-type variable area flow meter. The solid state design electronically senses movement of the magnetic piston assembly and provides accurate, repeatable flow measurements. The device has no mechanical linkages, which results in longer operating life.

All MR Flow Transmitters come pre-calibrated from the factory. However, the unit may also be user configured to meet specific application requirements. Calibration inputs are available for: specific gravity for all fluids, viscosity for petroleum-based fluids, as well as specific gravity, pressure, and temperature for pneumatic systems. Combined with user-selectable units of measure, these configuration functions allow for precise measurement without conversion calculations for unique applications. This helps overcome many of the drawbacks of mechanical direct-reading variable area flowmeters.

The company says the new line includes additional benefits and features:

  • Non-contact sensor electronics;

  • Digital flow rate and total flow indication;

  • Proportional analog output;

  • CE compliance, and unit also meets or exceeds U.S. and European standards from EMI/EMC; and

  • Low power consumption allows for 2-wire loop powered operation.

The MR Transmitters provide 0-5 Vdc, 0-10 Vdc, and 4-20 mA outputs, allowing for easy electronic integration. Optional remote display and signal processors are also available.

The F6700/F6750 Series Digital Display with integrated signal processor capabilities is offered to enhance the utility of the MR Flow Transmitters. In addition to remote flow monitoring, this unit can be configured to provide alarm processing and communication modes, including RS232, RS485, Modbus, Profibus and DeviceNet.

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
