The standpipe filter tip provides a filtered intake for standpipe piezo meters

The tip, available in polyethylene or porous stone, is supplied with adapters to fit 1/, 3/, and 1-inch standpipes.


Filter material Polyethylene tip is made from hydrophilic polyethylene and has 60 micron pores. Porous stone filter is made from fused aluminum oxide (Norton Alundum) and has 68 micron pores.
Filter Size Filter is 12 or 24 inches long and formed into 1.5" diameter cylinder.
Note on Plastic Pipe Couplings Slip couplings, although somewhat cheaper, sometimes catch falling bentonite, causing improper placement of the seal due to bridging. To prevent this, construct the riser pipe from flush-coupled plastic pipe. The smooth profile of the flush-coupled pipe allows bentonite chips to fall to the intended depth of the seal.
