The high precision flowmeter tube (at the left) indicates the measuring
range from 0 to 2 l/min, the "rough" flowmeter tube (at the right)
indicates the flow quantities from 2 to 15 l/min.

Because the dimensions of the lateral parts of the GME 2/3 can be altered
optionally, the use of flowmeter tubes of other manufacturers (e.g. Rota,
KDG and others) is possible.
