The Models 1903 and 1933 4-1/2" process gauges are
designed for process applications that require a panel
mounted gauge. The 1903 and 1933 gauges have a cast
aluminum front flange case with a lower-back mount
process connection. These models are available with
wetted surface material in brass/phosphor bronze and
316L, depending upon your needs.
