Paper & Pulp

Process Instruments is present in all markets where water is processed. All of these markets present their own challenges to monitoring and control and none more so than paper and pulp. With the high level of solids often present, monitoring anything in the water in the paper industry is challenging. Pi has been working with some of the industry leaders for more than 15 years and has solutions to many of the issues that arise including; the autoflush that can deal with 2% or 3% solids, the autoclean features of the ORP and pH sensors for dip or insertion installations and, online solids monitoring in the waste treatment processes. Contact Pi today to ask if we have a solution for your online monitoring and control problems.
