| Details:
BGK-4500 Series VW Piezometers are embedded into hydraulic structures, bedrocks or installed into piezometer riser pipes, boreholes, embankment pipelines and pressure vessels to measure pore pressure or liquid level. They are useable in various harsh environments with very excellent performances and special steel components. Taken measures of cable perfect protection, they can be embedded directly into roller compacted concretes of higher demand of instruments. The standard porous stones are made of sintered stainless steel with 55-micron holes for the sake of good water permeability.
BGK-4500AL is used in low pressure ranges. BGK-4500SV is designed for special ventilation cable connection to effectively overcome atmospheric pressure influences upon measurements.
