, digesters, clarifiers, and manhole lining applications.
Pulsar Process Measurement says it is is a world leader in non-contacting level measurement with tens of thousands of installations worldwide and the success of the business has been built on reliable, repeatable measurement systems that have made difficult or seemingly impossible measurements such as deep, cluttered sewage wet wells
or dusty grain silos a reality.
Suitable applications include submersible level measurements within irrigation systems, water and wastewater treatment, groundwater monitoring, wet wells
, points, rivers, and tank level measurement applications.
Tatweer has also been hard at work in installing new electrical submersible pumps in a number of its water wet wells
