Unbreakable Casagrande Piezometer
In old days + 50% Piezometer could not be used or abandoned as they were either damaged during transit or immediately after installations, as we often see muddy water in stand pipes. GAUGE developed special unbreakable filter element having 25-26 mm OD and 37-38mm OD and 2 feet single length (YES single length). This is connected by stainless steel tie rods, bottom plug and top socket for stand pipe.
