Axial Turbine Flowmeters

Drag Racing – Hoffer Leads the Pack in Drag Racing
For the past several years, Hoffer Flow Controls has been supplying turbine flowmeters to the automobile drag race world. Typically a small HO Series flowmeter with a magnetic pick-up coil is supplied to meter a nitro-methane fuel mixture on the supply side of the engine.

This allows the driver to monitor consumption during the race accurately. The flowmeter monitors both flow rate and total. This allows the car crew team to evaluate how much fuel was used during the race.

This is critical information in drag racing. A typical race is a ¼ mile and is completed in under 5 seconds. Approximately 5 gallons of fuel are used during the race, and the dragster is moving at over 300 miles per hour at the end of the race. The fuel consumption information is used to evaluate future car design changes.

Hoffer has been selected as the supplier of flowmeters by many race teams and car design teams.

A critical issue in the selection of a flowmeter is accuracy, response time, and low-pressure drop. The Hoffer HO precision series flow meters are supplied with 100% of the meter components precision machined.

No “cast” components are used. The low-mass rotor responds in 5 to 7 milliseconds. An additional consideration was the pressure drop created by the meter.

The Hoffer design provides a shallower blade angle than other turbine designs. This minimizes the pressure drop. The typical pressure drop on these meters is about 4 to 5 PSI at full scale. This is about half of what other turbine designs exhibit.

The combination of “winning features” on the Hoffer HO series of axial turbine flowmeters provides the maximum benefits to the race car world. This application adds a new dimension to auto racing. The winner in today’s race world is a combination of a talented driver and a car with the best design and instrumentation available.

About Hoffer Flow Controls

Hoffer Flow Controls has been designing and manufacturing quality liquid turbine flowmeters and related process instrumentation for more than fifty years. Our initial experience was in the field of cryogenic flow measurement. Today our reputation in this field is synonymous with quality. Today Hoffer Flow Controls manufactures high-precision turbine flowmeters to measure clean liquids and gases throughout the processing industries.

Axial Turbine Flowmeters from Hoffer Flow Controls

Hoffer Turbine Flowmeters are available in a broad range of standard and special materials. The wide range of construction options allows for selecting the optimum combination of useful range, corrosion resistance, and operating life for a particular application. A low mass rotor design allows for a rapid dynamic response which permits the turbine flowmeter to be used in pulsating flow applications.
