BM 70 M

If necessary, several holes can be drilled along the whole length of the pipe. All holes must be
deburred. The holes should be as small as possible and spaced wide apart (Recommendation:
see drawing below).
It is advisable to fit a reference point at the end of the stilling well in the form of a rod or screw of
approx. 6 mm (0.24") diameter. See drawing below.
6.1.5 Wave-Guide
The "Wave-Guide" is a pipe with an outside diameter of 30 mm (1.18") and an inside diameter of
25 mm (0.98"), that is bolted direct to the BM 70 flange system (in the same way as an antenna
extension). It functions like a stilling well and can be used for clean products. The Wave-Guide is
not practical in conjunction with the BM 70 M as it will not provide high measuring accuracy.
Maximum length:
Ex:
max. 3 m (9.84 ft) (except tantalum: max. 1 m (3.28 ft)).
Non-Ex:
up to 3 m (9.84 ft) without additional support
Pipes longer than 3 m (9.84 ft) need to be fixed at two points.
