Model 555 Pressure Transmitter
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, waste water processing, slurry and sludge measurements.
