Accurate turbine flowmeters.

Choosing the right device is an important decision and providing accurate flow measurement solutions is the specialty of Hoffer Flows Controls. Whether in applications in industrial plants, truck mounted or in the most severe environments, such as subsea or military.

Hoffer has the solution for your liquid and gas flow applications.

Hoffer Flows Controls Inc. was incorporated in 1969 in the state of New Jersey, US. Since then, Hoffer Flow Controls has been designing and manufacturing quality turbine flowmeters and related process instrumentation. The initial experience was in the field of cryogenic flow measurement. Nowadays, His reputation in this field is synonymous with quality.

Today, Hoffer Flow Controls manufactures high precision turbine flowmeters, not only for the cryogenic industry, but is world leader in turbine flowmeter technology for the measurement of clean liquids and gases throughout the processing industries. In addition, offers magnetic and ultrasonic flowmeters.

Custody transfer turbine flowmeters

The Hoffer CT Series turbine flowmeters provide extremely accurate custody transfer grade flow measurement. These flowmeters are typically used in liquid petroleum products, specially recommended for flow applications where high resolution (pulse count) is critical in order to achieve custody transfer grade accuracy.

Other Oil & Gas turbine flowmeters

  • High-pressure wing-nut flowmeters
  • Grooved oil-patch flowmeters
  • Wafer for gas service flowmeters
  • Subsea flowmeters
  • High-accuracy gas flowmeters
