The 4230 has built-in standard level-to-flow conversions
The device must be installed perpendicular to the slab it is inserted into
Why waste time with a small diameter bailer or bladder pump when the Supernova 120® will get the job done in a lot less time
and stable sensor technology provide minimal drift and increased accuracy with NIST-traceable factory calibration report
