For over thirty years Hoffer Flow Controls has been designing and manufacturing quality turbine flowmeters and related process instrumentation. Their initial experience was in the field of cryogenic flow measurement. The key feature in the high precision turbine flowmeter that differentiates them from other turbine flowmeters is the hybrid ceramic ball bearings. |
