Integral Shutoff for inline installation, Slurry and Sludge measurement
Designed for harsh abrasive slurry, the 555 has a unique feature which allows for wet installation in less than an hour through the use of a pipe saddle with integral shutoff. External adjustments and corrosive resistant wetted materials make this an excellent choice for pulp and paper, wastewater processing, slurry and sludge measurements.
