Wastewater treatment plants are challenged daily to ensure plant effluent meets or exceeds the state’s compliance limits. Treatment plants require field-proven process instrumentation to provide accurate and repeatable data for processes. Endress+Hauser’s Promag W unrestricted mounting 0 x DN electromagnetic flowmeter provides a solution for challenging applications by providing users with maximum measuring performance without concerns of pressure loss and typical straight pipe run requirements.


Constant recalibration – a time and money drain

The City was using an older technology that was not easy to validate. Personnel was comparing data with other meters they had installed downstream, and ultimately made decisions based on those comparisons. The older meter needed constant recalibration and its non-repeatable data was costing the City time and money. A new technology was needed. However, the space restrictions meant a new meter would have to be mounted with zero straight pipe run both upstream and downstream of the sensor tube.

After The City of Warren worked with an Endress+Hauser sales representative who shared the latest electromagnetic flow technology, they saw how this innovation fit their goals. They made the decision to upgrade the plant’s old flowmeter.


“We wanted a reliable product that provides accurate data at a competitive price,”

“A reliable product that provides accurate data enables you to make good decisions in your plant.”

“Any other meter would’ve been three or four times more expensive due to installation costs alone. The new meter fit perfectly in the existing footprint and didn’t require modifications to the piping.”
