Applications
Recommended for Liquids containing suspended solids or bubbles minimum size of 100 microns,
minimum concentration 75 ppm. Sensor mounts on Vertical or Horizontal pipes
Sensor Mounting Location 6-10 pipe diameters from elbows, tees (turbulence increasing devices) and
>30 pipe diameters from pumps, controlling valves and pipe discharge
Pipe Materials Steel, stainless steel, cast iron, PVC, fiberglass, any contigu-
ous pipe material that conducts sound, including lined pipes with
liner bonded to pipe wall. Avoid pipes with loose insertion lin-
ers and pipe walls which contain air (concrete, wood etc.)
