What is Stability and Why is it Important?

Stability is defined as a change (or lack of change) in accuracy over a period of time.

Drift is commonly used as a specification to illustrate the stability, or change in accuracy over a period of time, commonly shown as X%/year where X = a number; i.e. 0.25%/year. In this scenario, a device with a ±1% accuracy, would be expected to have an accuracy of ±1.25% (1%+0.25%) after a period of one year. Depending on the design, brand, and range of the sensing instrument, the stability can vary widely. Continue reading “What is Stability and Why is it Important?”

Lift Station Level Sensing

Lift Station with Pump Controller and Level Transmitter

Are you having problems with your current lift station level controls?  Dwyer Instruments may just have the cost effective solution you need.  In this article we will review several level sensing strategies, the advantages and disadvantages of each, as well as an option you may want to consider for your next project.

Lift Station Basics

In an ideal gravity fed wastewater collection system, sewage would flow downhill from its point of origin in residential or commercial areas to its final treatment plant destination.  Due to a number of factors including total distance, topography, geology, economics, etc., the ideal piping design is not always feasible.  Therefore, in most cases, sewage flows downhill to a lift station where it collects and then is pumped to a higher elevation in order to begin its downhill journey again. Continue reading “Lift Station Level Sensing”

Happy Holidays | Year in Retrospect


As the year comes to a close and we celebrate this time with our families and friends, all of us at Dwyer want to give a big thank you to the customers and teammates that we’ve depended on throughout the year. We certainly couldn’t have done it without you.

This year has been unlike any other, to say the least. The COVID-19 pandemic shook the world as hospitals and emergency personnel struggled to keep up with demand for ventilators and isolation rooms. Worldwide manufacturing slowed, as non-essential businesses shut down and companies shifted to CDC guidelines and recommendations. Continue reading “Happy Holidays | Year in Retrospect”

Sump Level Make-Up Water Controls in Wet Chemical Scrubbers

Maintaining efficiency in wet chemical scrubbers has become one of the most important missions of current APC facilities due to urban growth and plant expansion/modernization projects as good stewards of the community. Systems often run above the 90% efficiency mark with the help of accurate make-up water control instruments. Continue reading “Sump Level Make-Up Water Controls in Wet Chemical Scrubbers”
