Flowmeter communication: Rate indicator/totalizer extends sensor capabilities
New device works with frequency/pulse counting flowmeter sensors.
Installed flowmeter sensors can have their capabilities improved with the addition of more sophisticated transmitters. Hoffer has released a new indicator/totalizer designed to operate with turbine and other frequency producing sensors.
The new HRT1 is offered as an upgrade to the company’s HIT-2A rate indicator/totalizer which incorporates HART communications. The HRT1 reportedly enables customers to communicate to a processor via software or HART handheld communicator to adjust settings in the unit and check diagnostics.
HRT1 capabilities include rate, total, and grand total display. Output options include two alarm outputs configurable for rate and total, 20-point linearization, scaled pulse output, 4-20mA loop powered analog output, and the latest HART Version 7.

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.
