: length from center of the calibration window to the bottom of the flange
(77 mm (3.03 in) + flange thickness).
For JIS 10K 150A RF, the flange thickness is 22 mm (0.87 in).
• When using an asymmetric stilling well, take into account the lateral shift of the displacer
and follow the NMS8x mounting direction as shown in the figure.
• To calculate the required stilling well diameters, the formula below should be used. The
following tables contain the necessary parameters in order to calculate the dimensions of the
stilling well. Be sure to have appropriate dimensions of the stilling well according to each
dimension in the table.
• The radial direction offset (r) is required for only the 47 m (154.20 ft) and 55 m (180.45 ft)
wire drum. For all other drums, the offset is 0 mm/in.
