The pressure loss of the TBQM turbine meter is minimized through a dynamically optimized inlet diffusor, very low manufacturing tolerances and high precision, low friction ball bearings. The optimized flow conditions allow a minimal straight inlet pipe of 2 DN for low level flow disturbances and only 2 DN additional straight inlet pipe length under severe;y disturbed flow profile according to OIML standards. TBQM turbine meter housings are manufactured on a standard basis with raised face (RF) flanges according to DIN/EN 1092-1 or ANSI B 16.5 for class 150/300/600 with a maximum operating pressure of 100 bar/ 10 MPa.
