SPECIFICATIONS
FLOWTUBES
Flowtubes are fabricated from heavy walled, shock resistant, borosilicate glass with permanently
fused on ceramic scales. Bores are uniformly tapered with internal rib guides. Floats are retained
by Teflon
® plugs. Flow ranges are linear; low differential pressures are independent of flow rate
changes.
